Principal Software Engineer Software Engineering Boulder, CO Boulder, CO Austin, TX Full-time At Atom Computing, we build quantum computers using arrays of optically trapped neutral atoms that will empower customers to achieve unprecedented computational breakthroughs. Join a talented team of scientists, engineers, and business professionals to advance the state-of-the-art in quantum computing. We are seeking a Principal Software Engineer to provide technical leadership for the software platform that orchestrates our quantum computers. In this role, you'll set the technical direction for a core area of our stack: the systems that coordinate quantum computing workloads, interface with the hardware control and calibration systems, and manage the experimental data our systems produce, while driving the architecture of our next-generation systems. Reporting to the Software Engineering Manager, you will be responsible for leading the technical direction of a focused set of projects, partner with the team that owns our hardware control and compilation systems, and collaborate closely with our quantum engineers. This is a primarily backend role with occasional frontend work. Our backend services are written in Python and Rust, and our frontend components are written in TypeScript/React. Many of our services run directly on the quantum computers themselves, in a Linux environment, so you'll be writing and guiding software that operates close to the hardware. This role is based in our Boulder, CO or Austin, TX office.

Provide technical leadership for a core area of our software platform, guiding the design and execution of its projects and setting the technical direction that aligns your area with the broader team roadmap.

Drive architectural decisions across the software stack that orchestrates quantum computing on our systems, interfacing with (but not controlling) the hardware control and calibration systems owned by our partner team, and managing the experimental data our systems produce.

Invent novel technologies and solutions that advance our technology roadmap, contributing to inventions and patents where appropriate.

Rewrite and productionize prototype code written by our Quantum Engineers, turning research code into reliable, well-tested, maintainable services, and establishing the patterns the team builds on.

Mentor engineers across the team, raising the bar on code quality, design, documentation, and engineering practice.

Deploy, monitor, and support our production platform, sharing in a team on-call rotation to keep our quantum computers reliably available to customers.

Partner with our infrastructure team to strengthen our CI/CD pipelines, contributing improvements that speed up and stabilize how we ship.

Represent Atom Computing's engineering work externally where relevant, in customer and partner engagements and in the broader technical community.
