With Codespaces, we’re building and operating instant-on, remote cloud development environments. In this model, engineers work in cloud development environments — tailored for a specific project — where the overhead of launching a task-specific workbench is effectively zero. Work on a bug, review a change, or just try something out, all booted from a clean baseline ready for your commits. Not only does this accelerate engineers day to day coding, but it is also used across GitHub.com to iterate on and validate Copilot-generated code.

We are seeking a Staff Software Engineer to join this team and drive the continued evolution of Codespaces, shaping the future of cloud-based development for GitHub and its users. In this role you will play a critical role in shaping and implementing the future of the Codespaces product. You will work directly with developers and customers to help define the future of cloud development environments across GitHub.com. You will work with a strong team of developers to design and build a platform that is secure, reliable and most of all fun to develop on. Note, this Staff position is not only one where you get to design solutions, but one where you will have the opportunity to ship large features as part of the job.

As a software engineer at GitHub, you will enhance the collaboration experience at GitHub by working closely with a community of engineers and designers with a distributed, diverse and passionate team delivering the services that millions of developers depend on. In this role you will design, prototype, implement, ship and support highly performant and inspiring user experiences with your team. We are looking for creative problem solvers and diverse thinkers, people who care about culture as well as customers and features. We believe that how we do things is as important as what we do. Big vision, a common purpose, passion for quality, curiosity, dedication, and investment in fun and collaboration are what lead to great results. Great products reflect the teams that build them.

Job Responsibilities
