Overview

The Real-Time Communications (RTC) team is the foundation for real-time meetings, calling, and large-scale events in Microsoft Teams, supporting millions of sessions daily at the global scale. Our platform also serves as the backbone for multimodal capabilities, enabling agentic experiences across Microsoft 365 Copilot, W365, Microsoft Copilot Studio (MCS), Dynamics, and Azure OpenAI (AOAI). By integrating voice, video, screenshare, and artifacts in real time, IC3 provides reliable infrastructure and rich signals that power intelligent collaboration and AI-driven workflows throughout the Microsoft ecosystem. Our culture values collaboration, experimentation, and a growth mindset where team members are empowered to drive impact, challenge the status quo, and shape the future of AI-powered communications. Joining this team means working at the heart of Microsoft’s transformation, with opportunities to influence product direction and deliver solutions that touch millions of users worldwide.

Modern collaboration generates an immense stream of raw content—audio, video, and screen shares—that today remains locked in formats difficult to analyze or repurpose. This creates a gap between the richness of human interaction and our ability to extract actionable intelligence. Much of the semantic meaning in meetings is lost in basic transcription and recap, while the cost of transcription, screen analysis, and feature extraction makes it prohibitive to unlock insights at scale. To make meetings a first-class data source for Copilot and agents, we need an efficient, scalable infrastructure for multimodal feature extraction, starting with Teams, to transform real-time interactions into reusable knowledge. We are looking for Principal Software Engineer to join our team.

Location & Work Model: This role is based in Redmond, WA with an expectation of 3 days per week onsite. Candidates located outside of the Redmond area are considered for fully remote work.

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.
