At Medra, our mission is to use AI, robotics, and biology to accelerate life science research, with the ultimate goal of eradicating disease. We have been quietly building the foundational layers of our Physical AI Scientist platform:
🤖 Physical AI that can operate scientific instruments with human-level dexterity.
🧪 Scientific AI that can analyze results, reason about next steps, and close the loop autonomously.
This is an incredibly ambitious mission, but we believe that a team of ambitious people with high ownership can accomplish incredible things.
The Team:
• We're a team of passionate, mission-driven engineers and scientists from companies like Tesla, Amazon, SpaceX, and Neuralink. We're collaborative and love moving fast, both with our product and on team trips skiing or go-karting!
• As a team, we love nerding out about engineering and robotics — plus other topics like race cars or cooking. We like learning new things and then sharing our new knowledge with each other.
• Our team is opinionated and straightforward. We don't mind intense discussions about design tradeoffs. If we have arguments or miscommunication, we resolve conflicts quickly and empathetically.
The Role:
As a scientist on our forward-deployed team, your objective is to embed yourself with your scientific counterparts at the customer, acting as a true partner on their team to ensure that the Medra platform is achieving scientific outcomes and driving value for the organization. You will become an expert in our customer’s science, deeply understanding their scientific requirements and applying the scientific method (hypothesis, design, experimentation, analysis) to test and validate the fidelity of our Physical AI Scientist platform for their workflows. You will be in close communication with our end users (scientists) and have your eyes and ears on the ground to help us get ahead of any issues, while taking any insights and learnings from the customer back to the company to guide improvements to our product.
Internally, you will partner closely with the engagement manager and forward-deployed engineers to drive a successful deployment. You will work alongside an elite team of robotics, software, and hardware engineers to provide scientific oversight during scoping, build, and deployment. You will be a platform super-user who understands the strengths and limitations of our platform, and can apply creativity (& scientific intuition) to solve challenging problems.
We’re looking for someone who acts with urgency and thrives under pressure. This is a unique opportunity to use your skillset to what will be a step-change in drug discovery through artificial intelligence and robotics, and will offer significantly more exposure than working in a traditional biotech or pharma role.
In This Role, You Will:
Be the scientific subject matter expert - understand customer requirements and provide biological context to guide scoping, product development, and capability prioritization.
Design & execute wet-lab experiments to validate Medra’s autonomous Physical AI against scientific KPIs/metrics
Deploy on-site to our customer’s labs - embed with their scientists to validate the science, conduct hands-on training on the robot & instruments, and provide ongoing support as they ramp up usage
Own the installation, QC, and troubleshooting/error-handing for all laboratory instruments on the Physical AI platform
Support internal R&D on new protocols and assays, and explore emerging technologies & techniques
Keep detailed experimental records and documentation (SOPs) for all workflows

Keep the lab shift-ready: restock consumables, manage sample chain of custody, follow BSL-2 and EHS practices, and leave clear handoff notes so the day team and the platform can pick up seamlessly
B.S., B.A., or M.S. in Biology, Biochemistry, Biotechnology, Bioengineering, Chemistry, or a related scientific field
Hands-on wet-lab experience (industry experience preferred); we value deep bench skills over advanced degrees
Hands-on experience with some of the following: protein expression and purification, biophysical characterization, mammalian cell culture, or cell-based assays
Availability to work night and/or weekend shifts on a regular basis
Exceptional attention to detail and reliable follow-through; you run the same step the same way every time and notice when something looks off
Strong documentation habits and the ability to work independently and troubleshoot calmly
A fast learner with a scrappy, can-do attitude who wants to master new, multi-step workflows
Genuine enthusiasm for automation and robotics; you're excited to work alongside machines
Protein expression in mammalian (e.g., Expi293, ExpiCHO), microbial, or cell-free systems
High-throughput protein QC and biophysical characterization (SPR, BLI, DSF/DSC)

The Role:
We are looking for a Scientist to join our team and to develop and execute antibody screening and characterization on the Medra Physical AI platform. You will support our tissue culture operations, design and run in vitro and cell-based assays to characterize antibody candidates, and contribute to building out the lab capabilities that make all of this possible — from new assay formats to the automated workflows that execute them at scale.
This is a role for someone who blends scientific judgment with hands-on craft — someone who has designed and run antibody characterization and functional assays in high stakes settings and is energized by the idea of translating bench expertise into an autonomous lab. You will work closely with scientists and roboticists to develop and validate assays and bring them into routine execution on our platform.
In This Role, You Will:
Design, execute, and interpret antibody screening and characterization campaigns across the full funnel — from high-throughput primary hit triage through orthogonal confirmation
Develop and run cell-based binding and functional assays using flow cytometry to characterize antibodies, VHHs, and other binder formats
Run biophysical characterization on antibody candidates — including SPR and BLI for affinity and kinetics, and epitope binning — and interpret results to inform go/no-go
Execute developability assays to assess manufacturability and liability risks early — including thermal stability (DSF/DSC), aggregation and monomericity (HPLC-SEC), hydrophobicity (HPLC-HIC), polyspecificity/non-specific binding, and expression titer — and help triage candidates based on integrated characterization data
Maintain and engineer mammalian cell lines (e.g., Expi293, ExpiCHO, HEK293, CHO) and establish cell-based characterization and functional assays
Build out new lab capabilities end-to-end: scope the need, evaluate technologies, qualify instruments, write SOPs, and prepare validated workflows for autonomous execution
Partner with roboticists and software engineers to translate manual assay workflows into reliable, high-throughput autonomous protocols on the Medra platform
Maintain rigorous experimental records in electronic lab notebooks (ELN) and communicate results clearly to internal and external stakeholders
Let’s Talk If You Have:
Ph.D. in cell biology, immunology, biochemistry, or a related discipline with 2+ years of industry experience, or a B.S./M.S. with 6+ years of deep, hands-on industry experience.
Strong background in mammalian cell culture and sterile technique, with a track record of maintaining healthy, reproducible cell lines for assay work
Deep hands-on expertise in flow cytometry, including high-throughput formats and panel design
Demonstrated experience designing and executing cell-based functional assays for antibody characterization (binding, potency, mechanism-of-action, or similar)
Working understanding of antibody structure, function, and the therapeutic antibody discovery process
Comfort establishing target-overexpressing cell lines and evaluating/implementing new assay technologies
Strong documentation habits, attention to detail, and the ability to drive multiple workstreams in parallel
A scrappy, can-do attitude — you figure things out and get things done
(OPTIONAL) Bonus Points If You Have:
Experience screening antibodies against challenging target classes (e.g., GPCRs, ion channels, multi-pass membrane proteins)
Experience with alternative binder formats — VHHs, bispecifics, Fc-fusions, ADCs, or non-Ig scaffolds
Hands-on experience with lab automation and liquid handling platforms
Experience expressing and purifying antibodies in HEK293/CHO systems
Track record of developing and qualifying new assays or platforms from scratch

At Medra, our mission is to use AI, robotics, and biology to accelerate life science research, with the ultimate goal of eradicating disease. We have been quietly building the foundational layers of our Physical AI Scientist platform:
🤖 Physical AI that can operate scientific instruments with human-level dexterity.
🧪 Scientific AI that can analyze results, reason about next steps, and close the loop autonomously.
This is an incredibly ambitious mission, but we believe that a team of ambitious people with high ownership can accomplish incredible things.
The Team
We're a team of passionate, mission-driven engineers and scientists from companies like Tesla, Amazon, SpaceX, and Neuralink. We're collaborative and love moving fast, both with our product and on team trips skiing or go-karting!
As a team, we love nerding out about engineering and robotics — plus other topics like race cars or cooking. We like learning new things and then sharing our new knowledge with each other.
Our team is opinionated and straightforward. We don't mind intense discussions about design tradeoffs. If we have arguments or miscommunication, we resolve conflicts quickly and empathetically.
The Role
We are looking for a Scientist to own biophysical characterization on the Medra Physical AI platform. You will develop, validate, and scale label-free binding assays — primarily SPR and BLI — and turn them into robust, high-throughput workflows that run autonomously for our customers. Antibody affinity and kinetics, epitope binning, self-interaction, and quantitation are the daily bread of this role, and you’ll be responsible for making these assays reproducible, automation-ready, and reliable at a throughput and consistency that manual benchwork can’t match.
This is a role for someone who blends deep biophysical judgment with hands-on craft — someone who has designed and run SPR/BLI campaigns in high-stakes settings and is energized by the idea of translating that expertise into an autonomous lab. You will work closely with roboticists and software engineers to bring these assays into routine execution on our platform, and directly with customers to scope and deliver characterization campaigns.
Key Responsibilities:
Develop, validate, and run SPR and BLI assays across the full range of formats — affinity and kinetics, epitope binning, self-interaction (AC-SINS and BLI-based), and concentration/quantitation — on platforms including the Carterra LSA and Gator BLI
Design assay strategies for antibody and alternative binder characterization, selecting the right sensor chemistry, capture approach, regeneration conditions, and analysis models for each target and format
Build out new biophysical capabilities end-to-end: scope the need, evaluate technologies, qualify instruments, write SOPs, and prepare validated workflows for autonomous execution
Partner with roboticists and software engineers to translate manual SPR/BLI workflows into reliable, high-throughput autonomous protocols — including sample handling, plate setup, sensor/chip management, and data pipeline integration
Develop rigorous data analysis and QC frameworks for kinetics fitting, binning heatmaps, and developability flags, and interpret results to inform customer go/no-go decisions
Integrate biophysical data with orthogonal characterization — thermal stability (nanoDSF/DSC), aggregation and monomericity (HPLC-SEC/DLS), and polyspecificity — to give customers an integrated developability picture
Work directly with customers to scope characterization campaigns, communicate results clearly, and translate their scientific questions into executable assay plans
Maintain rigorous experimental records in electronic lab notebooks (ELN) and drive reproducibility across every assay you deploy
What You Bring to the Team
Ph.D. in biochemistry, biophysics, structural biology, or a related discipline with 2+ years of industry experience, or a B.S./M.S. with 6+ years of deep, hands-on industry experience.
Deep hands-on expertise with SPR and/or BLI — instrument operation, assay development, and data analysis — with a track record of generating high-quality kinetics data
Strong command of binding kinetics theory and its practical pitfalls: avidity, mass transport, regeneration, surface capacity, and fitting model selection
Demonstrated experience developing and qualifying biophysical assays from scratch, including method validation and troubleshooting
Working understanding of antibody structure, function, and the therapeutic antibody discovery and developability process
Strong documentation habits, attention to detail, and the ability to drive multiple workstreams in parallel
A scrappy, can-do attitude — you figure things out and get things done
Bonus Points For
Hands-on experience with high-throughput SPR platforms (e.g., Carterra LSA) and array-based epitope binning
Experience with alternative binder formats — VHHs, bispecifics, Fc-fusions, or non-Ig scaffolds
Hands-on experience with lab automation and liquid handling platforms (e.g., Lynx, Tempest, KingFisher)
Experience developing developability assay panels (nanoDSF/DLS, HPLC-SEC/HIC, AC-SINS) and integrating multi-instrument datasets
Experience building analysis pipelines or scripting for high-throughput kinetics data (Python/R)
Track record of developing and qualifying new assays or platforms from scratch
What We Offer
An opportunity to change the way that scientific research happens
Fast-paced, creative, and collaborative work environment
Significant equity ownership
401k
Medical insurance and dental insurance
Unlimited PTO
Weekday lunches and dinners

Build and own the post-training data pipelines integrating both internal data and public data
Create meaningful and trustworthy evaluations that tell us whether our models are improving scientific protocols and assay development
Develop agentic systems with context management and custom tool calls to surface new scientific insights about experimental design in real lab environments
Work closely with scientists, robotics engineers, and operation teams to bring reasoning capabilities into live experimental loops for leading biopharma partners
Shape the engineering culture and technical direction of a new machine learning team that's redefining how life science R&D gets done
Let's talk if you have:
Practical experience building AI-driven workflows into the real world
Strong problem solving skills for debugging complex systems
A clear grasp of probability, statistics, and ML fundamentals
Ability to own the post-training stack end-to-end: data pipelines, harnesses, RL environments, and agentic evaluations, even when things are loosely defined
Proficiency in Python and familiarity with at least one deep learning framework (e.g., PyTorch, JAX)
Experience with LLMs, post-training, reinforcement learning, or agentic systems
