Systems Architect
San Francisco, CA
Full-time
Onsite
Senior Level
5+ years expSygaldry Technologies is building quantum-accelerated AI servers to enhance AI training and inference. The Senior Systems Architect will be responsible for designing and analyzing the overall architecture of the server systems, ensuring efficient interconnection and performance of heterogeneous compute elements.
Artificial Intelligence (AI)HardwareQuantum Computing
Responsibilities
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)
Qualification
Required
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
