Description

Infleqtion's Computing Product Group is seeking a Senior Embedded Software Engineer to develop high-performance embedded and systems software for real-time quantum error correction and classical control. The role involves integrating NVIDIA high-speed interconnects with quantum error-correction decoding pipelines, collaborating with various engineering teams, and serving as a point-of-contact for hardware integration.

Required Skills

C/C++
Debugging
Computer Architecture Fundamentals
Linux-based embedded or HPC environments
GPU Programming Models (CUDA)

Additional Information

Required Previous Experiences: 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 Qualifications: High-performance computing (HPC) systems design or deployment.
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.
