We are hiring an experienced Principal Software Engineer on the Ads Engineering team to help expand the core capabilities of the Ads serving stack that powers ads on several online services ranging from Bing Search, MSN, Start.com, Edge Browser shopping, etc. The stack is a low-latency, high-scale geo-distributed system with multiple moving parts that include but not limited to large-scale ML inferencing infrastructure that rank ad-listings to real-time bidding infrastructure and other components to power a wide variety of Ad serving scenarios and use cases.  

This is an exciting opportunity to participate in the innovation and evolution of the stack, at a scale and pace very few other places can match. The challenges are plenty and the problems are varied from building new features to optimizing components of the entire stack as every millisecond matters to us, to building support infrastructure to run services in containers at scale. You will be part of a passionate and growing team that takes pride in their work. You will own and drive large feature areas and collaborate with some of the best engineers across the world. If you are someone that loves to tackle deep technical challenges and thrive in a fast-paced environment, then this is the place to be!
