Senior Software Engineer

Core AI is at the forefront of Microsoft’s mission to redefine how software is built and experienced. We are responsible for building the foundational platforms, services, programming models, and developer experiences that power the next generation of applications using Generative AI. Our work enables developers and enterprises to harness the full potential of AI to create intelligent, adaptive, and transformative software.

The 1ES (One Engineering System) team is responsible for enabling the world's best engineering teams with world-class tools and systems that help them ship products their customers love.

Developers rely on many components to build software, including open-source packages, container images and infrastructure-as-code configuration files. Keeping those components up to date is paramount to every modern application’s security and imposes a big cost on development teams. Moreover, the evolving environment of cybersecurity is such that new threat vectors are discovered often and require developers to quickly update their code to keep it protected.

The Developer Experience team is responsible for building services that boost developer productivity at Microsoft, and we are looking for Software Engineers who are excited about delivering ready-to-code environments equipped with AI capabilities to support engineering workflows.
