Senior Software Engineer, Copilot Agents

About GitHub 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. Locations In this role you can work from Remote, United Kingdom. Overview GitHub is the home for software development, where we collaborate to build the world's leading AI-powered developer platform. In the Copilot Agents organization at GitHub, we are passionate about ensuring the security and quality of the world's software—from open source to the enterprise. We believe that the best way to secure and improve the quality of software is to detect actionable issues early in the development process, and actively facilitate their remediation as part of the developer workflow. Copilot Code Review – an LLM-powered code review engine that provides feedback for immense volumes of code changes daily, helping developers fix bugs and improve the quality of their code, leading to faster time to merge. Copilot Autofix – an LLM-powered remediation engine that produces high-quality fix suggestions for security or quality findings, empowering developers to fix them as soon as they are found or reduce existing debt in their codebase. It is used as the remediation engine within the GitHub Code Security, GitHub Advanced Security, and Copilot code review products. CodeQL – a semantic code analysis engine that uses world-class static analysis research and technology to deeply analyze code, enabling the early detection of security vulnerabilities and correctness errors in software. CodeQL supports a wide range of programming languages, including C/C++, C#, Go, Java, JavaScript/TypeScript, Kotlin, Python, Ruby, and Swift, and is used as the primary detection engine within the GitHub Code Security and GitHub Advanced Security products. We work as a distributed group within a distributed company. The majority of our team members live across Europe, 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 security and code review 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 candidness and a culture that values safety to speak up are highly important to us. Responsibilities We are looking for a Senior Software Engineer to join one of the distributed software engineering teams responsible for building and expanding code analysis engines and agents at GitHub. You will work closely with various engineering teams, product managers, designers, and technical writers that build different aspects of the products, to influence product direction and deliver features to users, with clear focus on quality, reliability, and user experience. You will engage with internal users and external users (both from enterprise customers and the open-source community) to help them succeed with the product. You'll influence and provide feedback on the organizational culture and processes, always looking for opportunities to improve in a continuous pursuit of excellence.
