Job Level

Tech Stack

About the role

  • 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.
  • 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.

Requirements

  • 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.
