With over 270 million monthly active users, Microsoft Teams is the fastest‑growing business application in Microsoft’s history. It brings together the full power of Office 365 to help organizations collaborate and communicate effectively. The Core Services organization owns the foundational services that power Teams, handling billions of requests daily across public, sovereign, and government clouds. You will be joining the Mystics team (part of Core Services) which drives Safe Deployment Practices (SDP) and safe change management across all environments. In addition, we help bring Teams to newly created sovereign clouds. This role offers the chance to deepen your system design skills and work with a modern tech stack (.NET Core, containers, caching, Azure Cloud) while owning high‑impact, cross‑team initiatives. We’re looking for a proactive Senior Software Engineer with strong design, implementation, and automation experience. You’ll tackle core engineering challenges, build backend solutions, and collaborate across teams in a culture that values quality, innovation, automation, and business impact — directly influencing the experience of millions of users. 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.
