TL;DR · Senior Software Engineer

The Senior Software Engineer joins the COSMIC team within the M365 Substrate Core to build autonomous operational capabilities for Microsoft’s largest Kubernetes fleets. You will own significant features and services that enable AI agents to coordinate and safely execute operational workflows, including deployment, capacity, resiliency, recovery, and optimization. Your daily work involves designing distributed platform and orchestration components, establishing safety boundaries like sandbox isolation and policy checks, and driving production readiness through observability and health-gated releases. You will use languages such as C, C++, C#, Java, JavaScript, Python, or Rust to translate operational needs into testable software. This role solves the complex problem of modernizing compute platforms with turn-key geo-presence, fault isolation, and automated cloud buildout to improve service agility and reliability.
