About the role

  • This role focuses on integrating NVIDIA high‑speed interconnects with quantum error‑correction decoding pipelines, in close collaboration with quantum software, physics, and hardware teams.
  • The engineer will also serve as a point-of-contact (POC) for subsystem hardware integration with NVidia's NVQLink.
  • Serve as the technical point‑of‑contact for NVIDIA NVQLink integration, including topology, bandwidth modeling, latency characterization, and failure modes.

Responsibilities

  • POSITION SUMMARY Within Infleqtion's Computing Product Group (CPG), the Hardware Engineering Team is seeking a Senior Embedded Software Engineer to own and deliver high‑performance embedded and systems software enabling real‑time quantum error correction and classical control at scale.
  • Independently design, implement, validate, and maintain embedded and systems‑level software subsystems supporting real‑time quantum error correction and control.
  • Design systems that meet deterministic latency, bandwidth, and reliability requirements across CPU, GPU, FPGA, and high‑speed interconnect domains.
  • Collaborate closely with Quantum Software, Physics, Electrical, and Systems Engineering to co‑design hardware/software interfaces.

Requirements

  • Strong experience with C/C++ in performance‑critical systems.
  • Experience with hardware/software co‑design for quantum control systems Experience working in Linux‑based embedded or HPC environments.
  • Familiary with NVIDIA CUDA-Q Direct experience with NVIDIA Holoscan Sensor Bridge, RDMA over Converged Ethernet, or similar high‑speed coherent interconnects.
  • Familiarity with GPU programming models (CUDA or equivalent) at a systems level.

Nice to have

  • WE HOPE YOU HAVE: A degree (PhD preferred) in Computer Engineering, Electrical Engineering, Computer Science, or related field with experience in high-performance computing (HPC).
  • A degree (PhD preferred) in Computer Engineering, Electrical Engineering, Computer Science, or related field with experience in high-performance computing (HPC).

Compensation

  • $140k-$175k

Company info

  • At Infleqtion we solve the world's most challenging problems using cutting-edge quantum technology.
  • Our mission is to commercialize atom-based quantum products that provide orders of magnitude improvements in sensing and computing applications.
  • We are proud to work tirelessly to create and lead the quantum ecosystem towards meaningful advancements today and set the technology roadmap for tomorrow.
  • This position is scoped as a senior‑level individual contributor role: the engineer independently owns complex subsystems end‑to‑end within an established architecture, solves technically hard problems, interacts directly with external partners, and mentors developing engineers, without defining long‑term platform architecture.
