Senior Software Engineer, Code Scanning in London

In this role you can work from Remote, United Kingdom.

GitHub is the home for software development, where developers collaborate to build the world’s leading AI-powered developer platform. In the GitHub Code Scanning team, we are passionate about making the world’s software—both Open Source and Enterprise—secure and high quality. We believe that the best way to accomplish this is to detect security and quality issues early in the development process, and actively facilitate their remediation as part of the developer workflow.

Our team develops and operates the Code Scanning and Code Quality products that are part of GitHub’s Code Security offering. We use world‑class static analysis research and technology to deeply analyze code, enabling the early detection of security vulnerabilities and other bugs that testing and day‑to‑day use have missed. This role will be involved in the design, rollout and support of highly performant, highly scalable, and highly available services to make found‑means‑fixed a reality leveraging the power of agentic AI.

Come join our engineering team and help design, develop, and scale GitHub's Code Scanning feature. You will be working in a full-stack agile engineering team that’s part of the larger Code Scanning group working in Security Products. You will work with and learn from Senior and Staff engineers as well as influence team and product direction. In addition, we support and reward spending time on improving diversity, inclusion, and belonging, as well as other important improvement-work outside your core role as a software engineer.

We work as a distributed group within a distributed company. The majority of our team members live in Europe and on the east coast of the US and Canada, and while we do have some offices, all our meetings are location‑agnostic and happen online. We operate with a high degree of autonomy and trust, and we have a significant level of influence on the product and technical direction of Code Scanning, as well as the broader Security Products at GitHub. We value learning, introspection and reflection, and we’re always looking for ways to improve as a team and as individuals, so candor and a culture that values the safety to speak up are highly important to us.
