Overview
At the core of Microsoft Ads is a mission-critical, high-throughput real-time bidding (RTB) platform. It processes millions of auction requests per second and runs complex auction decisioning under strict latency constraints, directly influencing revenue, win rate, partner satisfaction, and overall reliability.
This role leads the platform's architectural and technical evolution with a focus on modernization, performance, scalability, experimentation infrastructure, and operational excellence. It requires deep expertise in low-latency distributed systems, proven leadership in large-scale refactoring and modernization programs, and strong cross-functional collaboration with engineering, data science, experimentation, and business stakeholders.
The engineer in this role drives initiatives with company-level impact, ensuring the platform can scale and evolve to support future Microsoft Ads growth.
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. Starting January 26, 2026, Microsoft AI (MAI) employees who live within a 50- mile commute of a designated Microsoft office in the U.S. or 25-mile commute of a non-U.S., country-specific location are expected to work from the office at least four days per week. This expectation is subject to local law and may vary by jurisdiction.
