We are looking for a Senior Software Engineer to help build a world-class coding agent CLI.
Overview
Within GitHub and Microsoft CoreAI, the Copilot CLI team builds GitHub’s coding agent in the terminal, and the core agent loop that powers agentic experiences across GitHub and Microsoft. Our work spans the full software development lifecycle, with a focus on turning modern AI systems into reliable, production-grade developer tools.
We are looking for a Senior Software Engineer to help build a world-class coding agent CLI. This role is for engineers who care deeply about product quality, end-to-end ownership, and the details that separate promising tools from ones developers trust and adopt daily.
Our work sits at the intersection of agentic AI systems and high-performance developer tooling. We are particularly interested in candidates with strength in one or more of the following areas:
Building, evaluating, and iterating on agentic systems, including tool design, agent loops, benchmarking, and quality optimization
Building delightful, high-performance terminal experiences, including terminal UIs, low-level primitives, and systems that feel fast, predictable, and polished
Engineers on this team operate with high autonomy and a strong product mindset. You will own large surface areas end-to-end, partner closely with product and design, and push to continuously raise the quality bar for both the CLI and the underlying agent platform used across GitHub and Microsoft.
Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As part of GitHub and CoreAI, we build developer tools that materially improve how software is written, reviewed, and shipped, while maintaining a culture of ownership, rigor, and technical excellence.
Microsoft’s mission is to empower every person and every organization on the planet to achieve more.
