Senior Software Engineer

Microsoft•Redmond, WA

About The Position

Microsoft Security is establishing a new Engineering Excellence organization to define and build world-class security engineering systems for the agentic AI era. The organization will create and scale core product-making systems that improve developer and builder productivity and enable AI-assisted workflows across Microsoft Security. The Senior Software Engineer will help design and scale AI-first engineering systems, shared platforms, and secure, compliant workflows that are broadly adopted across Microsoft Security. The role focuses on modernizing fragmented tooling into a cohesive foundation and establishing reusable standards for build, validation, observability, experimentation, and cost-aware design. The engineer will influence teams through systems that improve everyday engineering practice, not policy alone. The ideal candidate has hands-on experience with engineering infrastructure and developer toolchains, and can integrate AI into development workflows spanning coding, testing, deployment, and operations. They should be comfortable improving large codebases and tooling ecosystems, contributing to measurement systems, and building solutions within security, compliance, and policy constraints. Success requires strong execution, sound technical judgment, a focus on quality and reliability, and the ability to measure impact through engineering velocity, system health, and adoption of shared platforms.

Requirements

Bachelor's degree in Computer Science or a related technical field and 4+ years of technical engineering experience coding in languages such as C, C++, C#, Java, JavaScript, or Python, or equivalent experience.
Ability to meet Microsoft, customer, and/or government security screening requirements, including passing the Microsoft background and Microsoft Cloud background check upon hire or transfer and every two years thereafter.
Hands-on experience in engineering infrastructure and developer toolchains.
Ability to integrate AI into development workflows across coding, testing, deployment, and operations.
Comfort improving large codebases and tooling ecosystems, contributing to measurement systems, and building within security, compliance, and policy constraints.
Strong execution, sound technical judgment, and a focus on engineering quality and reliability.
