CoreAI 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 Artificial Intelligence (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 built by others, enabling code reuse, faster development cycles and increased quality. Moreover, Microsoft is a big contributor of open-source software, including .NET and Visual Studio Code. Ensuring the security of those components and a great developer experience is paramount to Microsoft’s core mission. 
 
The Open-Source Security and Tools team is seeking a software engineer who is passionate about open-source, developer productivity and security and will contribute to the ongoing growth and support of the engineering system powering Microsoft. The responsibilities will include: developing scalable distributed services scanning package managers like npm, NuGet and PyPi, collaborating with security teams, integrating new policies and scanners in our system, building a variety of tools that help Microsoft engineers consume and build open-source software that’s secure, supporting customers and the production services.

An understanding of how package managers work, how packages are built and installed in various languages and best practices for OSS development would be advantageous.
