Infleqtion is hiring a senior backend engineer to write the software that runs its neutral-atom quantum computers. About 90% of the job is hands-on coding: production services and control frameworks that operate and calibrate the machines, debugging the stack from embedded kernels to distributed services, and tooling that lets physicists run experiments themselves. The posting asks for six or more years of backend work, production Python plus C++ or Rust, and scientific data experience with NumPy, SciPy or PyTorch. On-site in Boulder, Colorado; $160,000–$185,000.
