Interested in being part of a team that powers a multi-billion-dollar business and helps shape the future of online advertising? Do you enjoy owning systems end to end, from distributed services and data to APIs and the applications customers use every day? Want to use AI to change how software is built and delivered? If so, we'd love to hear from you.
At Microsoft AI Experiences, Online advertising is one of the fastest-growing businesses on the Internet, and Microsoft Advertising is a leading global platform serving advertisers at massive scale. The Microsoft Advertising Campaign Management team builds and runs the platform that lets advertisers create, manage, analyze and optimize millions of campaigns across Microsoft's advertising ecosystem. That platform includes the services, APIs, data pipelines and web applications behind the advertiser experience.
We are starting a multi-year effort to modernize this platform. The work includes moving to cloud-native services, re-architecting core campaign workflows, adding AI-powered capabilities and improving engineering productivity. As a Principal Software Engineer, you will design and build solutions across every layer of the stack: backend services, APIs, data storage and processing, and the applications built on them. You will partner with engineering, product and design teams to deliver lasting improvements to how advertisers run their business.
The Principal Software Engineer will lead the design and implementation of high-impact features and platform investments, and own them from data model and service design through deployment and live-site operations. You will improve the scalability, reliability, latency and cost efficiency of systems that handle large volumes of advertiser data and transactions. You will also help advance AI-enabled engineering practices that speed up delivery and customer value.
This role suits a hands-on engineer who is comfortable anywhere in the stack, from distributed systems and data to the application layer. It also suits someone who enjoys solving hard technical problems, driving impact through technical leadership and building durable systems used by customers around the world.
