Principal Software Engineer

Principal Software Engineer – MAI Data, Privacy, and Security, Microsoft AI– Copilot – Microsoft Corporation. Mountain View, CA. As Microsoft continues to push the boundaries of AI, we are on the lookout for passionate individuals to work with us on the most interesting and challenging AI questions of our time. Our vision is bold and broad – to build systems that have true artificial intelligence across agents, applications, services, and infrastructure.

Security Engineering for Copilot is focused on building and securing systems that accelerate this process by making it easy and safe to incorporate more data and functionality that would otherwise be too scary/risky to do.

We are looking for a Principal Software Engineer to identify areas of risk and opportunity, then design and build solutions in Copilot, making the product and its platform more secure. This can include everything from secure coding standards, to API design, to infrastructure, sandboxing, automated testing/fuzzing, application security and intrusion detection. A key skill is the judgment to make the right risk vs velocity and value decisions.

You will possess a methodical approach to problem‑solving, proficiency in backend technologies, and the ability to architect solutions that stand the test of time.
