Senior Embedded Software Engineer - High-Performance Computing Orchestration

Overview In this role you design and implement high-performance software that blends classical and quantum resources to enable scalable quantum computing. You work with cross‑functional teams across software, hardware, and research to deliver latency‑ and throughput‑critical solutions. You will build interfaces across CPUs, GPUs, FPGAs, and quantum systems, and improve reliability and observability in demanding environments. This is an opportunity to shape the Infleqtion quantum platform while learning and contributing to a fast‑moving, collaborative field.
