Sygaldry Technologies is building quantum-accelerated AI servers to exponentially speed up training and inference for AI. By integrating quantum and AI, we're accelerating the path to superintelligence, and addressing the problem of rising compute costs and energy bottlenecks. Sygaldry AI servers combine multiple qubit types within a single, fault-tolerant architecture to deliver the combination of cost, scale, and speed necessary for advanced AI applications. We pioneer new domains in physics, engineering, and AI, tackling the hardest challenges with a grounded, optimistic, and rigorous culture. We're always looking for individuals ready to define the intersection of quantum and AI and drive its profound global impact.
Don’t See the Right Role Currently Posted?
We know great people don’t always fit neatly into a job description. If you’re excited about what we’re building but don’t see a current opening that matches your background, we’d still love to hear from you.
Who We’re Looking For
In addition to technical experience, we’re interested in people who dream big and execute small, who celebrate curiosity and forge their own path. We believe kind people build strong teams!
What to Tell Us
When you apply, please include:
A brief introduction about yourself
What excites you about Sygaldry
The type of work or role you're interested in
Links to relevant work, if applicable
Whether you could be available to work in our Ann Arbor or San Francisco office
What Happens Next
We review open applications on a rolling basis. If there’s a potential fit—either now or in the future—we’ll reach out to start a conversation.
Why This Matters
Your work accelerates the path to quantum superintelligence. Each quantum component integrated, each AI model enhanced, each instruction set optimized brings us closer to a future where intelligence and quantum mechanics are inextricably intertwined. We're not building incremental improvements - we're creating exponential transformations that will make AI more affordable, sustainable, personalized, and fundamentally more capable.
How We’re Different
At Sygaldry, curiosity and intellectual courage drive our work. We approach ambitious challenges with a grounded, optimistic, and rigorous culture and know that kind people build the strongest teams. We prioritize mission over ego and collaborate openly with a strong sense of shared purpose. We dream big, yet we execute with a love of detail. We’re looking for scientists, engineers, and operators to forge new paths with us at the intersection of quantum and AI.

We're looking for individuals ready to define the intersection of quantum and AI and drive its profound global impact.
Our AI & algorithms team develops quantum approaches to training, inference, and reasoning, including quantum-native generative modeling. Much of this work runs today on classical hardware at small scale, built so that results transfer directly to quantum processors as they come online.
Increasingly, that research meets real problems. Partner organizations bring workloads from their own domains, and someone has to carry our methods into each one and find out how well they hold. That is this role. You are a computational scientist who takes scoped collaboration and does the technical work: understand the partner's problem well enough to know where our methods can genuinely help, prototype, benchmark against what they already trust, and be the technical voice in the room when results are discussed. Our partnerships managers own the relationships and run the programs; our research scientists develop the algorithms. You produce the evidence.
Applied Work in Partner Domains
Assess where our quantum-native generative methods apply to a specific domain: which algorithm, under what assumptions, in which regime it wins, and what would count as evidence
Build and run the proof-of-concept work, and adapt research-team implementations to relevant domains
Validate against the reference methods the partner already trusts, whether that's molecular dynamics, Monte Carlo, a classical solver, or their production model
Present and refine results in technical working sessions, and carry what you learn -- model scales, data characteristics, evaluation criteria -- back into decisions about what we develop next
Benchmarking & Evidence
Produce evidence by whichever route fits the question: approximate simulation where a structured representation scales, circuit emulation where exact small-scale results matter, and analytic resource models to reach past what either can run
Design benchmarks that hold up: quantum, classical, and hybrid compared under realistic assumptions, against the strongest classical method rather than a convenient one
Use our internal modeling and simulation environment to show a partner what their own workload would look like on our architecture
Extend those models to new algorithm workloads, and produce the charts, comparisons, and reproduction artifacts behind our published and partner-facing results
Are a scientist who ships: you write code daily, and your results are reproducible by someone else
Are quantitatively deep enough to judge whether a result is right, not only whether the pipeline ran
Can hold a technical conversation with a domain expert in a field you didn't train in, and come out knowing where the real bottleneck is
Value rigor: you are comfortable assessing where quantitative methods help, where they don't, and what evidence distinguishes the two
Move fast, and can carry several engagements in parallel without letting any of them go stale
Advanced training (MS, PhD) in a computational field -- physics, chemistry, applied mathematics, computational biology, engineering -- or equivalent depth built in industry
Strong Python and scientific computing: linear algebra, ODE/SDE solvers, sampling and Monte Carlo methods, uncertainty quantification
Generative modeling experience: diffusion, flow matching, normalizing flows, score-based or energy-based models
Exposure to tensor network methods or other structured representations for high-dimensional problems
Applied domain experience in molecular or materials modeling, time-series forecasting, physical simulation, or generative design
Technical writing ability, and a track record of reproducible research artifacts or collaborative publications
Curiosity about quantum computing; prior experience is welcome but not required
