Jobs in Bedford, United Kingdom

GitHub is the world’s leading platform for agentic software development — powered by Copilot to build, scale, and deliver secure software. Over 180 million developers, including more than 90% of the Fortune 100 companies, use GitHub to collaborate, and more than 77,000 organisations have adopted GitHub Copilot.

In this role you can work from Remote, United Kingdom

As a Software Engineer III 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 the Git teams of GitHub! Git Systems enables all Git Operations for GitHub dotcom. If you’ve ever run git push on your local machine to share changes on GitHub then you’ve interacted with our services and infrastructure. We serve billions of git requests daily; if you want to work at scale, Git Systems is an incredible opportunity!

Git Systems is a distributed team across Europe and North America composed of 3 teams: Git Protocols, Git Platform, and Git Storage. Git Protocols provides external access by terminating all http and ssh requests. Git Platform serves and routes requests for access to git data. And finally, Git Storage stores, replicates, and hosts our git data. The 3 teams work in tandem, but this position is on the Git Storage team. Each team manages their own infrastructure to support their services, though we partner closely with our Infrastructure teams.

To maintain high availability of our critical services we run a 24/7/365 on-call rotation. This is a shared rotation across our 3 teams, broken into two 12-hour shifts each day – one in North America and Europe respectively. Engineers are expected to join the rotation within their first 6 months in the role.

Want to know a little more about Git Storage? Storage is responsible for the persistent storage and replication of all repository data for Github dotcom. It is the infrastructure-heavy team in Git Systems, maintaining our fleet of file servers and MySQL databases that host 40+PiB of the world’s most valuable data. Git Storage also maintains GitHub’s backup and restore service. Our team is directly responsible for the services that store and serve 450M+ Git repositories, both directly to users and to other layers in the GitHub software stack. Infrastructure experience is helpful for engineers on our team, but not a requirement.

Examples of previous work within this group include:

• improving large monorepo performance
• championing efficient ways of working with Git repositories
• working on Git itself

• Design, develop, test, and ship high-quality technical solutions that scale across multiple GitHub services.

• Own and advocate for the health and quality of the systems that the team builds, including participating in on-call and first responder rotations.
• Write architecture briefs and proposals, carry out code experiments, and build prototypes to learn how we can achieve planetary scale with our systems.
• Contribute to the development of design documents for designs with oversight from senior colleagues, determine the technology that will be leveraged, and how that technology will interact.
• Design and implement APIs to facilitate seamless integration between software components.
• Utilize CI/CD tools to set up automated pipelines for continuous integration and delivery.
• Become intimately familiar with the systems you build and take pride in writing maintainable code.
