OverviewWithin the Developer Division, the Languages, Runtimes, and Compilers Group at Microsoft is responsible for best-in-class support for C++, Java, .NET (C#, Visual Basic, and F#), Python, Rust, and Go. Developer Division in Core AI believes that software development is rapidly evolving in the age of AI. We are building the future of platforms and tools for this new era-and we are looking for developers who are not only early adopters of AI-powered development tools, but who are also actively exploring how large language models (LLMs) can enhance their effectiveness and impact. Be a part of a team that values collaboration and the idea of working better together. Come and help us define the language, optimize the compiler and runtime, and build tools that empower developers worldwide to build great software. If you are ready to take on your next big challenge, join us to help redefine the future of developer tools. We are building the next generation of Python development experiences, combining state-of-the-art language services with AI-powered assistance. Our team owns pylance, the leading Python language server, and debugpy, the Python debugger behind Visual Studio Code. We are now pushing further into the age of AI: integrating with GitHub Copilot, improving agent chat context with real-time diagnostic and linting insights, developing Model Context Protocol (MCP) tools, and reimagining debugging and software development in a world where AI and humans collaborate closely. We are looking for a Software Engineer II to contribute at the forefront of this transformation. You will work on cutting-edge problems in language tooling, debugging, static analysis, and AI-assisted development - and shape the experience of millions of Python developers worldwide. Microsoft's mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
