Skills: Python, Rust, CI/CD
Summary This role helps the scientists who build and operate QuEra's neutral-atom quantum computers program those machines effectively. You will maintain the domain-specific language and compiler stack, built on the open-source Kirin toolchain, that experimental physicists use every day to run their experiments. You will work closely with physicists and control stack engineers. You'll help machine teams turn new experiments into working programs, keep the toolchain reliable as our hardware evolves, and drive its integration with our control system. The role suits an engineer who enjoys building tools and also helping others succeed with them. Responsibilities Maintain the domain-specific language and its compilation stack: triage issues, fix bugs, review pull requests, manage releases and keep CI, tests and dependencies healthy. Act as the point of contact for machine and testbed teams programming their experiments. Help them build new experiments, port legacy programs and diagnose compilation or runtime problems. Work with control stack engineers on integrating compiled programs with our control system. This includes defining and evolving the program representation passed between the compiler and the control system, keeping the two in sync across releases, and debugging problems that span both. Turn user problems into minimal reproducible reports, regression tests and focused fixes, and work with the compiler team on larger language or IR changes. Find and fix performance problems in program compilation and execution, such as compile time, program size and timing correctness. Write and maintain user-facing documentation, tutorials, example programs and agent skills that make it easier for physicists to write correct programs. Work with the hardware control team to support new channel types, control hardware and machine configurations. Collect feedback from machine users and turn it into a prioritized roadmap for usability improvements. Qualifications Bachelor's or…
