We are looking for a Senior Software Engineer who is passionate about developer agility and improving the speed, reliability, and efficiency of Copilot development. In this role, you will design and build backend, data, and ML systems that empower teams across E+D(M365 Core, OPG, GXP, etc) to develop and deploy Copilot capabilities with greater velocity and confidence. You’ll partner closely with other engineers, product managers, and applied scientists to identify bottlenecks, improve workflows, and deliver key initiatives such as the Copilot Data Platform. The qualified candidate is an AI-forward engineer, who can ramp up quickly on new projects, thrive in fast-paced, ambiguous environments, and make an immediate impact. You’ll contribute both to foundational engineering work and to AI adoption initiatives that drive agility across the Copilot ecosystem.

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.
