Senior Software Engineer

Join Microsoft AI, a team at the forefront of developing cutting-edge technologies. We build and operate one of the largest distributed systems in existence, powering Microsoft Ads and delivering billions of ad requests globally under tight latency, cost, and reliability constraints. Delivering relevant ads efficiently at this scale requires innovation across the full stack: models, kernels, serving systems, and GPU/accelerator infrastructure. This is a self-motivated and results-driven environment that will unleash your potential. As a Senior Software Engineer, you will lead the design and development of low-latency, high-throughput services in C++, architect scalable microservices, and optimize system performance across CPU and GPU. You will collaborate with cross-functional teams, influence technical direction, and mentor engineers while driving engineering excellence.
