Principal Software Engineering Manager- GPU Inference Optimization

The R&D of Search Ads aims to build an online advertising ecosystem of users, advertisers, and the search engine.
Bing Search Ads Understanding team is chartered to deliver world class algorithm using web scale data. Our mission is to drive user satisfaction, advertiser ROI and Bing revenue. A core challenge is to match advertisers' "Ad display" and users' "query" by build an intelligent system to really understand the users need. This is a very hard problem that demands the most advanced AI models and sophisticated engineering systems. Join us to work on projects highly strategic to Bing search in a fun and fast-paced environment!
We are hiring a Principal Software Engineering Manager (GPU Inference Optimization) to lead the team effort on GPU inference optimization of large and small language models to support the GPU serving of the models for Ads tasks including retrieval, relevance and creative generation, etc. As a manager of this team, you will have the opportunity to lead the innovations of the fundamental abstractions, programming models, runtimes, libraries and APIs to enable large scale inferencing and online serving of models on novel AI hardware.
This is a lead role focused on GPU inference optimization of large and small language models: it requires hands-on software development skills and expiernce to lead the team efforts by applying the model-coach-care practices. We’re looking for someone who has a demonstrated history of solving hard technical problems and is motivated to tackle the hardest problems in building a full end-to-end AI stack. An entrepreneurial approach and ability to take initiative and move fast are essential.
