Senior Software Engineer

Commercial Engineering & AI (CEAI) partners closely with stakeholders to accelerate the transformation of Microsoft’s commercial business into a frontier organization. We bring together AI‑native engineering, modern platforms, and deep commercial insight to reimagine how work gets done - at scale and with impact. Our mission is to unlock new ways of operating through intelligent systems while creating the conditions for our teams to do the most meaningful work of their careers. If you’re excited to build, experiment, and shape the future of commercial execution with AI at the core, we invite you to apply. Within this context, the Scale and Partner AI Experiences (SPAI) organization is at the forefront of transforming Microsoft’s partners ecosystem through AI-first innovation. Our mission is to build intelligent, scalable platforms that power partner and customer success, accelerating Microsoft’s commercial growth through modern, AI-driven experiences. As a Senior Software Engineer, you will design and ship core components of the agentic platform that field sellers and partner teams rely on daily. You own features end to end, from prototype to production, working across orchestration, grounding, evals, observability, and the SDK surfaces other engineers build on. You take real ownership of what you ship, help raise the bar for how agents are built and evaluated on the team, and grow your influence as you go. This role is for an engineer with a bias for action who already builds with Claude Code, Codex, MCP, or open-source agent stacks, and who follows the frontier closely. If that's you, this role gives you the surface area to do it at a global scale.
