Responsibilities
Independently design, implement, validate, and maintain embedded and systems‑level software subsystems supporting real‑time quantum error correction and control
Translate quantum error‑correction requirements (code distance, syndrome rates, latency budgets) into concrete classical compute, memory, and interconnect requirements
Design systems that meet deterministic latency, bandwidth, and reliability requirements across CPU, GPU, FPGA, and high‑speed interconnect domains
Serve as the technical point‑of‑contact for NVIDIA NVQLink integration, including topology, bandwidth modeling, latency characterization, and failure modes. Involves direct interaction with NVIDIA personnel as well as HPC experts in academia and US national labs
Collaborate closely with Quantum Software, Physics, Electrical, and Systems Engineering to co‑design hardware/software interfaces
Troubleshoot and resolve complex performance, scaling, and integration issues spanning firmware, drivers, OS (Embedded Linux / bare-metal environments), GPU runtimes, and hardware
Develop and maintain validation infrastructure, performance benchmarks, and test harnesses for deterministic behavior and scaling
Provide informal mentorship through design reviews, code reviews, and technical guidance
Qualification
Required
A degree (PhD preferred) in Computer Engineering, Electrical Engineering, Computer Science, or related field with experience in high-performance computing (HPC)
Demonstrated experience owning complex embedded or systems‑level software subsystems end‑to‑end
Strong experience with C/C++ in performance‑critical systems
Experience debugging across software and hardware boundaries (drivers, firmware, interconnects, timing)
Solid understanding of computer architecture fundamentals (memory hierarchies, interconnects, latency vs throughput tradeoffs)
Experience with hardware/software co‑design for quantum control systems
Experience working in Linux‑based embedded or HPC environments
Familiarity with GPU programming models (CUDA or equivalent) at a systems level
Preferred
High‑performance computing (HPC) systems design or deployment
Familiarity with NVIDIA CUDA-Q
Direct experience with NVIDIA Holoscan Sensor Bridge, RDMA over Converged Ethernet, or similar high‑speed coherent interconnects
Experience supporting or developing error‑correction decoding pipelines (quantum or classical)
Background similar to advanced academic research groups in quantum architectures or decoding (e.g., large‑scale syndrome decoding research)
Experience performance‑modeling compute systems as a function of problem size and algorithmic complexity
Exposure to FPGA‑accelerated or heterogeneous compute systems
Detail-oriented mindset with a strong sense of ownership and technical accountability
Positive, collaborative working style and enthusiasm for mentoring and developing engineers
