About the Role
You own verification end to end for a first-of-its-kind chiplet. As a founding hire you define the methodology before there's RTL to verify — this role is on the critical path, and getting the coverage strategy and regression infrastructure right early is the single biggest schedule lever we have.
What You'll Own
The full DV strategy: verification plan, coverage model (functional + code), UVM architecture, and signoff criteria from block to full-chip.
Stand up regression/CI infrastructure and nightly runs before design hands over first RTL.
Verification of the in-house engines against an algorithmic golden model, with programmable error injection and error-pattern coverage.
Hardware-assisted verification: bring up and own the emulation / FPGA-prototyping methodology.
UCIe VIP and compliance, link-training, loopback, lane-repair scenarios, bit-exact transparency and more.
Performance and throughput verification.
UVM register verification, firmware co-simulation, and boot flows on the MCU subsystem.
Mixed-signal co-simulation — verifying the digital front end against behavioral models of analog/mixed-signal blocks.
Gate-level and low-power (UPF) verification as part of signoff.
Lead and grow the DV team (across FEC, UCIe, MCU, datapath, and full-chip).
Required
10+ years ASIC/SoC verification, with team leadership on at least one complex SoC from plan to tapeout.
Proven leadership verifying large, complex digital SoCs / subsystems, including interconnect fabric and full-chip closure.
Deep UVM/SystemVerilog; coverage-driven verification; constrained-random methodology.
Hands-on with hardware-assisted verification — emulation (e.g., Palladium/Veloce) and/or FPGA prototyping (e.g., HAPS/Protium).
Comfortable with mixed-signal verification (Verilog-AMS or SV real models).
Regression/CI at scale (grid, triage automation), and rigorous coverage closure.
Preferred
High-speed SerDes, PAM4, or FEC/coding (Reed-Solomon) verification experience.
UCIe, PCIe/CXL, Ethernet, UALink or comparable die-to-die / link-layer VIP and compliance experience.
NIC Cards, Ethernet/IB Switches, Cache-coherency verification (multi-core / coherent fabric).

About the Role
You own verification end to end for a first-of-its-kind chiplet. As a founding hire you define the methodology before there's RTL to verify — this role is on the critical path, and getting the coverage strategy and regression infrastructure right early is the single biggest schedule lever we have.
About the role. You define the digital front-end micro-architecture — the spec the design team implements — and personally own the high-speed datapath that moves data between UCIe and the optical front end. This is the architectural center of the chip: the datapath, the UCIe streaming interface, in-house IP, and the interface to the optical engine all converge in your blocks. As a founding hire you set the partitioning, interfaces, and coding/CDC standards the whole front end follows.
What you'll own
Front-end micro-architecture and block partitioning; the architecture spec the RTL team builds to.
Front-end design methodology and quality: RTL coding standards, lint, CDC/RDC signoff, and clean-RTL policy across the team.
The high-speed datapath: per-lane alignment/deskew/mux, the UCIe streaming /RDI adapter, elastic FIFOs, and custom logic.
Transport/link framing/mapping and the adaptation logic.
Timing- and floorplan-aware micro-architecture: pipelining, retiming, and partitioning for physical closure at multi-hundred-Gbps (with the backend team).
Clocking, reset, and low-power architecture — clock/reset domains, gating strategy, and UPF power intent.
Establish designer-level verification: block-level testbenches/sanity checks and assertion (SVA) coverage that designers own before handoff to DV.
Architectural DFT and debug provisioning — scan-friendly structure and on-die observability/controllability for a die you can't probe (with the DFT and DV leads).
IP integration and interface/register conventions; parameterization for configurability across lane counts/configurations.
Architectural trade-offs with the modelling lead (latency, buffering, datapath sampling/observability) and the DV lead (verifiability and debug).
Lead, grow, and mentor the front-end design team as the group scales (datapath, interfaces, integration).
Required
10+ years digital design / micro-architecture, with lead ownership of a high-throughput datapath or SerDes-adjacent SoC.
Experience designing the datapath of a network switch/NIC card or memory controller at a major XPU / fabric vendor (or a comparable high-throughput, high-reliability datapath).
Solid understanding of scale-up vs. scale-out interconnect architectures and their bandwidth/latency trade-offs.
Strong SystemVerilog RTL and timing-aware micro-architecture at multi-hundred-Gbps aggregate rates; CDC discipline.
Working command of UCIe/PCIe/CXL datapath concepts and high-speed lane alignment/deskew.
Proven ownership of front-end design methodology — lint/CDC/RDC signoff, clocking/reset architecture, and design-for-test and physical-closure collaboration.
Track record translating system requirements into an implementable, verifiable architecture spec.
Preferred
UCIe (or PCIe/CXL/CHI) interface architecture; die-to-die / chiplet experience.
FEC/coding datapath familiarity (e.g., Reed-Solomon) and gray-code mapping.
Optical transceiver, CPO, or linear-drive optics background; advanced-node (N5/N3/N2) design experience.
What We Offer
Competitive salary commensurate with experience

About Lumilens
At Lumilens we are building the critical photonics infrastructure that powers tomorrow’s AI supercomputing. From chip-to-chip optical interconnects to scalable photonic engines, Lumilens is unlocking a new era of computing faster, cooler, and massively more efficient.
We’re a well-funded startup backed by Mayfield and led by veterans who’ve built and scaled some of the most transformative technologies in the industry.
This isn’t incremental innovation, it’s a ground-floor opportunity to rethink the optical layer from the silicon up. The market is moving fast, and we’re moving faster. You’ll work alongside a team of world-class engineers solving some of the hardest challenges in optics, systems, and scale. Every line of code, every design decision, every breakthrough you help deliver will shape the infrastructure of tomorrow.
If you're looking for mission, momentum, and the chance to make an outsized impact, jump on the rocket ship. We’re just getting started.
About the role. You will build the executable model of the chip before silicon exists. Your architecture models will settle the decisions that are expensive to change late, including datapath latency, throughput, buffer sizing, and control-loop tuning. Your reference models will become the golden checkers the verification team scores against, and the platform will run real firmware months ahead of RTL. This is a founding, critical-path role: the virtual platform is what unblocks the firmware and architecture work in parallel with design.
What You'll Own
A SystemC/TLM-2.0 virtual platform — MCU (ISS-backed) + peripherals + memory map + a UCIe transactor + host stub — that firmware runs on pre-RTL.
Architecture/performance models: architectural trade studies, end-to-end datapath throughput and latency, FIFO/buffer sizing, design-space/configuration exploration.
Golden reference models handed to DV as scoreboards.
Behavioral models of the analog and control circuits.
Partner with the FE architect and firmware lead to keep model, RTL, and firmware views coherent.
Required
8+ years in architecture/performance modelling or virtual-platform development for complex SoCs.
Strong SystemC and TLM-2.0; solid modern C++.
Built or led a virtual platform / ESL model that real firmware ran on for pre-silicon bring-up.
Integrating a third-party ISS (e.g., Arm or RISC-V) into a SystemC/TLM platform; modelling buses, memory maps, and peripherals.
Architecture/performance modelling judgment — knowing what to abstract versus model faithfully.
Comfortable spanning hardware micro-architecture and embedded software.
Preferred
Familiarity with High-speed serial links and die-to-die / chiplet interconnects, and link-layer concepts such as FEC and equalization (e.g. PCIe, UALink, Ethernet or memory-semantic interconnects like CXL).
Experience feeding golden models into a UVM/DV verification flow.
Modelling for mixed-signal or optical/SerDes systems, including control-loop / plant modelling.
High-throughput datapath modelling.
What We Offer
Competitive salary commensurate with experience
Comprehensive benefits package including health, dental, and vision
Professional development opportunities and certification support
Access to cutting-edge technology and cloud platforms
Collaborative work environment with cross-functional teams
Lumilens is an equal opportunity employer. All qualified applicants will receive consideration without regard to race, color, religion, gender identity, sexual orientation, veteran status, disability, or any other legally protected status.

Assess supplier financial health, manufacturing capacity, and technology roadmap alignment.
Support commercial negotiations for pricing, capacity commitments, and supply agreements with optics/photonics suppliers
Partner with engineering and product teams to translate technology roadmaps into sourcing plans, well ahead of production needs.
Own cost-reduction roadmaps for key commodities, tracking savings against targets.
Supply Risk Management
Maintain visibility of long-lead and critical-path optical components across the supply base.
Proactively identify and mitigate supply risks: allocation constraints, single-source exposure, geopolitical/export-control exposure, and capacity shortfalls.
Build contingency and dual-source plans for critical components identified as at-risk.
Cross-Functional Collaboration
Partner cross-functionally with engineering, operations, and program management to translate product requirements into scalable supply chain strategies
Work closely with engineering on component specifications, alternate part qualification, and second-source enablement.
Support contract manufacturing (CM) partners with supplier introductions and component allocation, where components are consigned or CM-managed.
Analytics & Reporting
Track supplier performance: on-time delivery, quality (PPM/yield), cost trends, and capacity utilization.
Maintain a sourcing and supply roadmap and risk dashboard for optics/photonics commodities, reporting regularly to supply chain and engineering leadership.
Qualifications
Bachelor’s degree in engineering, Materials Science, Supply Chain, or related field
5+ years of sourcing/procurement and supply chain experience
Proven track record negotiating supply agreements and managing supplier relationships across Asia and other global regions.
Excellent analytical and cross-functional stakeholder management skills.
The role
Lumilens builds optical interconnect for AI data centers: silicon photonics, mixed-signal ICs, electrical-optical interposers, and the systems around them. Our silicon ships in production AI clusters today, and volume is climbing fast.
You will develop and own production test programs for our mixed-signal ICs — the SerDes, TIAs, modulator drivers, and control silicon at the heart of our co-packaged optics and pluggable transceivers. You will take test content from bring-up on the bench through to release at the OSAT, and stay with it through production.
Singapore puts you inside the assembly and test supply chain we depend on. You will be hands-on with our test partners in the region, working alongside a senior test engineer and partnering with design and validation teams across the US, India, and Singapore.
This is the role where you go from executing someone else's test plan to owning your own.
What you'll do
Own test program development for assigned devices or blocks: build the test list against the coverage plan, and take it through wafer sort and final test insertions.
Develop, debug, and optimize ATE test programs for mixed-signal and high-speed devices — analog and DC parameters, high-speed signal path, on-chip test points, digital scan, and firmware-driven test modes.
Support test hardware bring-up: review load board and probe card designs, debug hardware issues in the lab, and work with vendors through first article.
Participate in first-silicon bring-up alongside design and validation. Correlate ATE results to bench characterization, and investigate when they disagree.
Be the day-to-day technical contact for your programs at our OSATs: release, correlation across testers and sites, multi-site and test time optimization, and production support.
Analyze sort and final test data to find yield limiters, marginal tests, and guard-band problems. Drive the fixes on your devices and support failure analysis on returns and excursions.
Build the reusable test IP, scripts, and data tooling that make the whole team faster.
What we're looking for
BS/MS in Electrical Engineering, Computer Engineering, Physics, or a related field.
3–5 years developing production test for mixed-signal or high-speed ICs, including at least one test program you took to production release.
Hands-on ATE experience on at least one major platform (Advantest 93K or T2000, Teradyne UltraFLEX or J750, Eagle, Chroma, or comparable).
Strong programming: C/C++ and Python, on Linux. You write test code other engineers can read and extend.
Solid analog and mixed-signal fundamentals — you can read a schematic, reason about a datasheet spec, and design the measurement that proves it.
Practical test hardware skills: load board and probe card debug, bench instrumentation (scopes, BERTs, SMUs, network analyzers, VNAs), and lab troubleshooting.
Working knowledge of optical systems and networks: how an optical transceiver works, optical power and link budgets, and high-speed serial protocols such as Ethernet and PAM4 signaling.
Statistical fluency for yield and correlation work — JMP, MATLAB, Python/pandas, or equivalent.
Some exposure to OSAT or subcontract test operations, and comfort working with external partners.
Willingness to travel regionally to test sites, and to overlap with US and India hours when a bring-up or an excursion calls for it.
Preferred Qualifications
Silicon photonics, optical transceiver, or opto-electrical test background — coupled-fiber test, optical power and wavelength measurement, TIA and driver characterization.
High-speed SerDes test experience: BER, jitter decomposition, eye margining, loopback methods.
DFT familiarity: scan, MBIST, JTAG/IEEE 1149, on-chip instrumentation and monitors.
STDF and test data pipelines; building analytics that engineers actually use.
Experience supporting a product through its first production ramp.
Why this role
Optical I/O for AI is being defined right now, and test is one of the places where it is won or lost — a part that cannot be screened economically does not ship, however good the design. The team is small, so your programs are yours: you will see your test content go from a bench setup to millions of parts, and grow into owning test architecture as we scale.

Lumilens builds optical interconnect for AI data centers: silicon photonics, mixed-signal ICs, electrical-optical interposers, and the systems around them. Our silicon ships in production AI clusters today, and volume is climbing fast.
You will own layout for our electronic ICs (EICs) and photonic ICs (PICs). These are high-speed analog blocks where the layout is the design: a parasitic you did not anticipate, a return path you did not control, or a current density you did not check will cost the part its margin.
You will also support photonic IC (PIC) layout as our schedule demands, and own the integration of electronic and photonic dies as they come together.
Singapore puts you close to the assembly and test supply chain we depend on, working alongside a senior layout engineer and partnering with design teams across the US, India, and Singapore.
Responsibilities
Own layout for assigned analog and mixed-signal blocks: device placement, matching and symmetry, shielding, guard rings, and routing, from floorplan through to clean sign-off.
Execute parasitic-aware layout — build to the constraints given by designers, run extraction, and take the results back to them when the layout says something the schematic did not expect.
Route high-speed signal paths with attention to impedance, coupling, and return paths, and lay out passive and electromagnetic structures under senior direction.
Run and close DRC, LVS, antenna, and density checks on your blocks, and support electromigration and IR drop analysis.
Support top-level assembly and chip finishing activities through tape out.
Support PIC layout as the need arises, including waveguide and curvilinear structures.
Lay out photonic components and waveguide routing — bends, tapers, couplers, grating and edge couplers, and modulator and photodetector electrodes — from designer-provided geometry, honoring minimum bend radius, waveguide spacing, and phase- and length-matching constraints.
Run photonics-specific verification: curvilinear DRC against the photonics PDK, waveguide connectivity and port checks, LVS on custom photonic cells, and clean GDS stream-out for tape out.
Build the scripts and reusable structures that make the layout team faster.
Qualifications
Diploma, BS, or MS in Electrical or Electronics Engineering, or equivalent hands-on layout experience.
1–3 years in custom analog, RF, or mixed-signal IC layout, including at least one tapeout you contributed to through to silicon.
Solid working experience with Cadence Virtuoso, including Layout XL and constraint-driven flows.
Parasitic awareness in practice — you understand why a matched pair is drawn the way it is, and which nets on your block deserve the extra care.
Fundamentals in electromigration and IR drop: current density limits, power routing, and the checks that catch problems.
Fundamentals in electromagnetics for on-chip structures — coupling, shielding, and why high-speed routing is constrained the way it is.
Physical verification experience: Calibre or PVS DRC/LVS, and parasitic extraction with QRC, StarRC, or equivalent.
Some scripting for layout automation — SKILL, Python, or both.
Willingness to overlap with US and India hours during tape out crunch.
Preferred Qualifications
SiGe BiCMOS layout experience, and the passive and isolation practices those processes demand.
Advanced FinFET CMOS layout at 7nm and below — multi-patterning and coloring, fin and poly grid constraints, and the DRC complexity that comes with them.
Photonic IC layout exposure: waveguide routing, curvilinear geometry, and photonics PDK design rules.
Experience with parametric photonic cells (PCells) in Virtuoso SKILL or Python-based photonic layout tools (gdsfactory, KLayout, IPKISS), and with curvilinear-to-grid snapping and fracture rules.
Familiarity with silicon photonics building blocks and their layout sensitivities: Mach-Zehnder and ring modulators, Ge photodetectors, thermal phase shifters, and fiber coupling structures.
Exposure to 2.5D and 3D integration, interposers, or micro-bump and copper pillar arrays.
Layout on optical front ends specifically — TIA, modulator driver, or high-speed serial link blocks.
Why this role
Optical I/O for AI is being defined right now, and in this silicon the layout is where the performance is actually won. The team is small, so the blocks are yours: you will take them from floorplan to tapeout, see them come back as working parts, and grow into top-level and methodology ownership as we scale. You will also get a working foot in photonics, which very few layout engineers have.

Responsibilities
Block and top-level layout
Own floorplan and layout for high-speed analog and mixed-signal blocks: TIAs, drivers, SerDes front ends, PLL and clocking, references and bias.
Execute device-level matching and symmetry — common-centroid, dummies, shielding, guard rings, substrate isolation — to the level these circuits actually require.
Route high-speed signal paths with control over impedance, coupling, and return paths. Lay out passive and electromagnetic structures (inductors, transformers, transmission lines) and work with designers through EM simulation.
Own chip finishing: pad ring, bump and pillar maps, seal ring, density fill, and top-level assembly through tape out.
Physical closure
Drive parasitic-aware layout: iterate with designers on extraction results and close the loop between what the schematic assumed and what the layout delivers.
Own electromigration and IR drop closure — current density, power grid construction, and the analysis that proves it holds at temperature and lifetime.
Take blocks through DRC, LVS, antenna, DFM, and ESD and latch-up checks to sign-off.
Photonics and integration
Support PIC layout as the need arises: waveguide and curvilinear structures, and the design rules that come with a photonics platform.
Own layout of photonic blocks: waveguide routing under bend-radius, spacing, and length-matching constraints; modulator (MZM, ring) and photodetector electrode layout co-optimized with the RF drive path; and grating and edge coupler placement against fiber-attach and packaging constraints.
Build and maintain the photonic PCell library and PDK integration in Virtuoso — curvilinear geometry generation, SKILL and Python automation, grid snapping and stream-out, and DRC/LVS methodology for custom photonic cells.
Own the EIC-PIC integration — micro-bump and pillar alignment, interposer interfaces, and the co-layout decisions that make the electrical path work across two dies.
Methodology and team
Set layout standards here: reusable structures, PDK and tech file evaluation, automation, documentation, and review practice.
Mentor junior layout engineers as the Singapore team grows, and represent layout in design reviews with real authority.
Qualifications
Diploma, BS, or MS in Electrical or Electronics Engineering, or equivalent hands-on layout experience.
8+ years in custom analog, RF, or high-speed mixed-signal IC layout, including multiple tape outs you saw through to silicon.
Expert-level Cadence Virtuoso, including Layout XL and constraint-driven flows.
