Senior Software Engineer

Microsoft Teams remains the backbone of enterprise collaboration at Microsoft and for millions of users globally. Today, we stand at the forefront of a new era in the future of work, where AI-powered agents and intelligent experiences are transforming how people collaborate. These new capabilities have already proven transformative in enhancing productivity and teamwork for Microsoft and our customers. At Microsoft, we’ve embraced this evolution—human intelligence is now augmented by AI tools to vastly improve our productivity and collaborative possibilities. And Teams is at the center of it all, acting as the hub that brings people, content, and workflows together in the age of AI, redefining how we plan, meet, decide, and drive impact in organizations.

At Microsoft Teams AI Platform, we are building the core platform that enables these innovations. We own the client framework that underpins all of Microsoft Teams’ extensibility – powering first-party Microsoft apps as well as third-party partner apps within Teams. This framework is what allows developers (inside and outside Microsoft) to seamlessly integrate their apps and services into Teams, turning it into a rich, extensible hub for daily work. Now, with the rise of AI, our platform also hosts cutting-edge AI features and agents in Teams, enabling intelligent assistance and automation directly in the flow of work. By embedding AI agents into daily workflows through Teams, we are amplifying human capabilities, reducing friction, and unlocking new levels of productivity across organizations. These AI experiences – from smart meeting assistants to workflow automation bots – boost collaboration and innovation by allowing people to focus on higher-value tasks while routine or complex tasks are handled by AI. It’s an exciting time where AI and agents are shaping the future of work, and Microsoft Teams plays a pivotal role in bringing that future to every employee’s desk.

Joining our team as a Senior Software Engineer means having a direct hand in shaping the future of intelligent collaboration at massive scale. You will work on one of Microsoft’s most strategic products, building a platform that impacts hundreds of millions of users and helps define how AI and apps come together to empower people to achieve more. Our team culture is passionate about innovation, quality, and customer success. We collaborate closely, we move fast, and we take pride in building solutions that are robust and scalable.

If you are excited by the idea of working on AI-powered platforms and want to redefine how the world works together, this role is for you.

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
