About this role

Overview
SPARTANs take on strategic projects and hard problems across M365 Core that remove agility and modernization barriers. This team enters unfamiliar problem spaces quickly, builds a defensible technical model, frames the work, and owns outcomes through deployment and measured impact. The role spans repositories, services, and organizational boundaries and must leave durable solutions, reusable patterns, documentation, and playbooks behind.
Engineers on this team operate with high autonomy and a strong product mindset. You will own large surface areas end-to-end, partner closely with product and design, and push to continuously raise the quality bar for both the CLI and the underlying agent platform used across GitHub and Microsoft.
Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.

Responsibilities
Technical depth: writes and reviews clean, testable, observable code and gains confidence quickly in unfamiliar codebases.
Distributed-systems judgment: designs high-scale, low-latency, always-on services with explicit reliability, performance, cost, and compliance tradeoffs.
Mission execution: converts open-ended asks into scoped projects with success criteria, milestones, risk management, deployment, and measurable impact.
Influence without authority: aligns partners, negotiates dependencies, resolves disagreement, and lands changes across boundaries.
Develop AI-first. Use AI tools with discipline across the whole development lifecycle, from requirements and design to code, tests, and operations. Own the quality of everything AI produces, and help the team raise its bar on AI-assisted engineering.
Solid judgment: makes timely calls under incomplete information, states tradeoffs, and changes direction when evidence changes.
Community leadership: help early-in-career engineers and other engineers, communicates crisply, and builds an inclusive environment.
