Help reinvent how advertising outcomes are measured in the AI era. You’ll join Microsoft Advertising in building the always-on measurement foundations that power performance, trust, and optimization at global scale. You’ll work on systems that transform raw conversion events into actionable attribution signals—so advertisers can understand what worked, what didn’t, and how to improve as customer journeys evolve.

As a Senior Software Engineer on the Conversion & Attribution engineering team, you will strengthen the near real-time conversion pipeline—collecting and processing conversion events with low latency, and producing attribution signals used for reporting and campaign optimization. You’ll raise the bar on reliability, observability, and operational excellence for business-critical services, and help evolve our attribution platform toward a more unified, configurable architecture that supports cross-scenario needs.

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.
