Applied AI Engineer

<div class="content-intro"><h2><strong>About AssemblyAI</strong></h2> <p>AssemblyAI builds the best-in-class Speech AI models powering the next generation of voice applications. Our models serve 600M+ inference calls monthly, process 1M+ hours of audio daily, and power 2 billion+ end-user experiences—from voice agents and meeting assistants to contact centers and medical scribes. Companies like Zoom, Granola, Fireflies, Cluely, and Calabrio rely on AssemblyAI to ship production-ready voice AI.</p> <p>We're at an inflection point in Speech AI. We released Universal-Streaming in mid-2025, and it has quickly earned its place as the model offering the best accuracy-latency-cost tradeoff on the market. Our research team drives these advances and ships with relentless velocity. Since releasing Universal-Streaming, we've already launched <a href="https://www.assemblyai.com/blog/streaming-keyterms-prompting">keyterms prompting feature</a> and <a href="https://www.assemblyai.com/blog/introducing-multilingual-universal-streaming">multilingual support</a>—with more significant improvements on the roadmap.</p> <p>We've raised $115M+ from Accel, Insight Partners, Y Combinator's AI Fund, Patrick and John Collison, Nat Friedman, and Daniel Gross. We're a remote team building one of the next great AI companies—and we're looking for researchers who will shape its future.</p></div><h3><strong>About the Role:</strong></h3> <p>We're looking for an Applied AI Engineer to join our team at the intersection of cutting-edge AI research and real-world customer applications.
