Overview

Microsoft Digital (MSD) builds and manages the critical products and services that Microsoft runs on. We boldly pursue big ideas that power transformational advances at Microsoft and for our customers, while helping Microsoft teams work smarter, faster, and more securely every day. Microsoft Digital employees have deep technical and business expertise, customer insights, and a clear point of view that comes from first-hand, large-scale experience with Microsoft and industry solutions. We are engineers, technology leaders and experts, digital transformation change agents, and customer advocates.

We have exciting opportunities for you to innovate, influence, transform, inspire, and grow within our organization and we encourage you to apply to learn more!

We're a growing team looking for a passionate Senior Software Engineer. In this role, you'll help define and build the next generation of our agentic platform, orchestrating the latest AI models and harnesses in service of company-wide developer productivity.

Our work spans the full lifecycle of agentic systems in production. We design and improve the core capabilities that shape agent behavior, including tool design, planning and execution loops, orchestration, evaluation, and safety guardrails. We build the AI fundamentals that make those systems dependable in practice, including observability, progressive delivery, and reliability engineering. And we build the best user experience for our customers to use these agents from any device seamlessly.  

We are looking for a full stack AI Software Engineer teammate to help build this next generation of agentic systems. Engineers on our team operate with high autonomy in a highly agile environment: short cycles, thin slices, feature flags, progressive delivery, and constant learning. We are looking for teammates with strong owner’s mindset and a strong bias for action - engineers who take ownership of ambiguous problems, adopt modern science research, engineering patterns & practices, move quickly, learn from production, and continuously raise the quality bar as they ship.

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.
