About Sygaldry 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 looking for individuals ready to define the intersection of quantum and AI and drive its profound global impact.
About the Role:
As a Senior Systems Architect, you are responsible for the overall architecture of the server that will connect to GPU/XPU scale-up networks and will enable the quantum computing sub-systems to exponentially speed up production training and inference workloads. You will design, analyze, and model how heterogeneous compute elements interconnect, synchronize, and scale—focusing on GPU scale-up fabrics, collective communication, and system-level performance bottlenecks. This is a hands-on architecture role for someone who enjoys moving between whiteboard-level system design, performance modeling, and lightweight simulation/emulation, with direct influence on hardware, firmware, and software co-design decisions.

What You’ll Work On:
System Architecture
Cross-Functional Collaboration
You May Be a Good Fit If You
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.
Culture & Benefits
We encourage applications from candidates with diverse backgrounds. We are an equal opportunity employer, and we do not discriminate on the basis of race, religion, color, national origin, sex, sexual orientation, age, veteran status, disability, genetic information, or other applicable legally protected characteristic.
We encourage you to apply even if you do not believe you meet every single qualification. If you don’t think this role is right for you, but you believe that you would have something meaningful to to contribute to our mission, please reach out at letsbuild@sygaldry.com
