Senior Software Engineer

Microsoft Microsoft · Big Tech · Redmond, WA +1 · Software Engineering

Senior Software Engineer role focused on building foundational security capabilities for Microsoft's security cloud, emphasizing identity, data security, and platform engineering. The role involves designing, implementing, and shipping reusable security primitives that ensure secure-by-default behavior, reduce systemic risk, and simplify least-privilege and data protection practices across Microsoft's services and developer ecosystem.

What you'd actually do

  1. Design, implement, and ship core security capabilities that are reused across services, focusing on correctness, scalability, and long‑term maintainability.
  2. Own well‑scoped problem areas end‑to‑end, translating security requirements into concrete designs, high‑quality code, and production‑ready solutions.
  3. Work across identity, authorization, and data boundaries to deliver least‑privilege and data‑protection improvements that meaningfully reduce real‑world risk.
  4. Collaborate closely with partner engineering teams, integrating with shared platforms and ensuring solutions are usable, adoptable, and reliable in practice.
  5. Operate effectively in high‑throughput, multi‑tenant environments, making sound engineering trade‑offs around performance, safety, and operational readiness.
  6. Raise the engineering bar through design reviews, code reviews, and mentorship, helping improve quality and clarity within the team
