Principal Software Engineer(Data)
Microsoft
Conversion and attribution are core business capabilities for measuring advertising effectiveness and optimizing ad delivery. They directly influence advertisers’ understanding of performance, budget allocation, and automated bidding decisions. As privacy requirements continue to tighten and cross-site tracking capabilities gradually diminish, the advertising measurement ecosystem is evolving away from approaches that rely on traditional identifiers toward conversion and attribution mechanisms that are more compliant, sustainable, and explainable.
Conversion team is responsible for building and operating these core conversion and attribution capabilities. By focusing on the generation, interpretation, and delivery of conversion signals, the team enables advertising performance measurement, delivery optimization, and scalable business growth. Its work spans the entire advertising lifecycle and places extremely high demands on business correctness, timeliness, and reliability, forming a critical foundation of a trusted measurement platform.
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.
