Systems Architect

System Architecture

Architect end-to-end heterogeneous compute systems spanning CPUs, GPUs, accelerators, and quantum-adjacent subsystems.

Analyze scale-up interconnects (e.g., NVLink, UALink, Infinity Fabric, or equivalent) and their impact on latency, bandwidth, and synchronization.

Design timing arcs, critical paths, and throughput models across complex multi-device systems.

Identify system-level bottlenecks in training, inference, and reinforcement learning workflows at hyperscaler scale.

Model and reason about GPU collective operations (e.g., NCCL, RCCL, or equivalents) across nodes, racks, and pods.

Evaluate how collective communication patterns interact with emerging accelerators and non-GPU compute elements. Work with software and firmware teams to ensure architectural assumptions map cleanly to real-world implementations.

Act as a bridge between hardware, systems, and software teams, translating requirements and constraints across domains.

Collaborate with quantum hardware engineers to define clean interfaces and timing contracts—without requiring quantum domain expertise.

Engage with external partners and ecosystems (e.g., interconnect standards bodies, silicon vendors, hyperscaler partners).

Have least five years of experience architecting similarly complex high performance systems deployed in production datacenters

Are familiar with GPU scale-up domains generally, such as NVLink, UALink or other scale-up architectures

Are familiar with the AI training and inference workflows in large (i.e. hyperscaler) data centers and the main bottlenecks in training, training and reinforcement learning

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.

We’re building the infrastructure for quantum superintelligence and pioneering new domains at the intersection of physics, engineering, and AI. 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.
