Senior Embedded Software Engineer - High-Performance Computing Orchestration

Job Responsibilities

• Designing, developing, testing, and maintaining high-quality software for high-performance quantum-classical computing systems.
• Building software components and interfaces that coordinate computation across classical and quantum computing resources.
• Developing systems that operate under demanding latency, throughput, bandwidth, and reliability requirements.
• Integrating software with heterogeneous computing platforms including CPUs, GPUs, FPGAs, accelerators, and high-speed networking or interconnect technologies.
• Analyzing system performance, identifying bottlenecks, and improving scalability and reliability.
• Developing tools, benchmarks, test infrastructure, and observability capabilities for complex computing systems.
• Troubleshooting challenges spanning applications, operating systems, drivers, runtimes, networking, firmware, and hardware.
• Collaborating with software engineers, physicists, electrical engineers, systems engineers, external technology partners, and researchers to develop new computing capabilities.
• Writing maintainable, well-tested software and contributing to code reviews, design reviews, and technical documentation.
• Providing technical guidance and mentorship to other engineers.
• Rapidly evaluating and prototyping new technologies as the quantum and high-performance computing ecosystem evolves.

You do not need previous quantum-computing experience to be successful in this role.

We are looking for exceptional software and systems engineers who are excited to learn the quantum domain.

Experience in one or more of the following areas is beneficial, but we do not expect candidates to have experience in all of them:

• Ability to learn quickly, reason about complex computing systems and turn difficultrequirementsinto reliable software
• High-performance computing (HPC) systems, supercomputing environments, or HPC job schedulers such as Slurm or PBS.
• GPU or accelerator programming, including CUDA or similar programming models.
• Distributed systems, high-performance networking, or low-latency communication.
• RoCE,RDMA, high-speed Ethernet, Infini Band, or other high-bandwidth interconnect technologies.
• Heterogeneous computing involving CPUs, GPUs, FPGAs, or other accelerators.
• Embedded Linux, firmware, device drivers, or hardware/software integration.
• Performance profiling, benchmarking, modeling, and optimization.
• Scientific computing, numerical computing, or research software.
• Real-time or latency-sensitive systems.
• FPGA-accelerated computing.
• Quantum computing, quantum control, quantum error correction, or quantum software frameworks such as CUDA-Q.
• Developing software in R&D or rapid-prototyping environments.
• Collaborating with external scientific, academic, government, or technology partners.
• Open-source software development.

This position is a senior-level individual contributor role. You will independently own significant software and systems problems from design through implementation, validation, integration, and deployment. You will collaborate closely with technical leads and engineers across disciplines and will have opportunities to influence the evolution of Infleqtion’s quantum computing platform.
