Overview: Our team is at the forefront of transforming digital advertising through intelligent automation and large-scale optimization. We design and build the auto-bidding platform that powers real-time ad auctions across Microsoft’s marketplaces, leveraging AI, machine learning, and large-scale distributed systems to bid on behalf of millions of advertisers. Our systems process billions of auction events daily, optimizing bids in milliseconds to maximize advertiser ROI and return on ad spend. Engineers and scientists collaborate to blend algorithmic innovation, reinforcement learning, and robust data pipelines to drive Microsoft Advertising’s success. We’re seeking a Principal Software Engineer who thrives at the intersection of AI systems, real-time decision-making, and scalable cloud infrastructure. You will help shape the next generation of our agentic auto-bidding platform—one that learns, adapts, and optimizes autonomously. Your work will directly influence advertiser ROI and drive billions of dollars in revenue across Bing, MSN, and the Microsoft ecosystem.
