We are looking for a Software Engineer II to join the Special Projects and Resources Team (SPARTANs) in M365 Core - Substrate. SPARTANs take on strategic projects and difficult engineering problems across M365 Core, removing agility, modernization, AI Acceleration barriers for engineers throughout Substrate.

Substrate is the data and intelligence platform that underpins Microsoft 365. It enables partner teams to build, operate, and modernize compliant and reliable services at global scale. SPARTANs help the organization move faster and deliver greater impact by establishing outcome-oriented missions that unblock critical programs in areas such as modernization, resilience, cost optimization, compliance, and developer productivity.

As a Software Engineer II on SPARTANs, you will work across different services and codebases to solve clearly scoped portions of complex engineering problems. You will collaborate with experienced engineers and partner teams to understand unfamiliar systems, develop and validate solutions, and deliver measurable improvements. This role offers an opportunity to strengthen your distributed-systems expertise while contributing to high-impact projects across Microsoft 365.

Our team is dedicated to serving others and leaving every system and engineering organization stronger than we found it. We value technical curiosity, sound engineering judgment, collaboration, continuous learning, and measurable customer impact.

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. We work with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. We build on the values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive.
