We are hiring a Software Engineer to join the Ads Engineering team, where you’ll be at the forefront of building infrastructure to bootstrap and host LLM agents and MCP servers at scale. This work is foundational to enabling intelligent, responsive systems that support next-generation ad delivery and optimization. Our team is also leading the development of Copilot solutions designed specifically for DRIs, integrating agents and MCP servers to provide real-time visibility into system health and performance. These tools empower the DRI team to maintain operational stability and proactively address issues across our systems. 

In parallel, you will contribute to the evolution of the Ads serving stack that powers advertising across Bing Search, MSN, Start.com, Edge Browser shopping, and other Microsoft services. This stack is a low-latency, geo-distributed system operating at massive scale, handling complex workloads such as large-scale ML inferencing for ad ranking, real-time bidding, and a variety of ad-serving scenarios. Every millisecond counts, and the engineering challenges span from feature innovation to deep optimization across the stack. 

You will own and drive significant feature areas, collaborate with top engineers across the globe, and contribute to a system that supports billions of ad impressions daily. The role demands strong technical depth, a proactive mindset, and the ability to work independently while influencing cross-team efforts. If you thrive on solving deep technical challenges and want to be part of a team that is shaping the future of large-scale intelligent infrastructure, this is the place to be.
