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:
This role is focused on the architecting of high-performing AI hardware, and does not require prior knowledge of quantum computers. 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. We will share more detail about this role during in-person discussions.
You May Be a Good Fit If You Have:
Architected end-to-end heterogeneous compute systems spanning CPUs, GPUs and novel accelerators.
Analyzed scale-up interconnects (e.g., NVLink, UALink, Infinity Fabric, or equivalent) and their impact on latency, bandwidth, and synchronization of high performance AI hardware
Designed timing arcs, critical paths, and throughput models across complex multi-device systems.
Identified system-level bottlenecks in training, inference, and reinforcement learning workflows at hyperscaler scale.
Modeled and reasoned about GPU collective operations (e.g., NCCL, RCCL, or equivalents) across nodes, racks, and pods.
Evaluated how collective communication patterns interact with emerging accelerators and non-GPU compute elements.
Worked with software and firmware teams to ensure architectural assumptions map cleanly to real-world implementations.
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.
