SoundCloud empowers artists, tastemakers and fans to connect and share through music. Founded in 2007, SoundCloud is a creator-first platform helping artists build and grow their careers by providing them with the most advanced tools, services, and resources. With over 4x the music catalog of every other major streaming platform, spanning 40+ million artists across 190+ countries, SoundCloud is where emerging artists find their sound, hidden gems are discovered, and music culture is shaped in real time.

SoundCloud is seeking a Machine Learning leader to architect the next era of Musical Intelligence at SoundCloud. As a Senior Principal Engineer, you will combine deep technical expertise with strategic vision and people leadership to drive the development of large-scale recommendation, personalization, and search systems. The mission is clear: architect systems to extract high-fidelity insights from user interactions with the world’s largest audio dataset to connect artists and fans through music. You will define the technical North Star for ML across engineering, delivering impactful data-driven products while leading and growing a high-performing team of Engineers and Scientists. This role reports directly to the Chief Technology Officer and will work in lockstep with the Music Intelligence, Content, and Recommendations teams. You will also be part of a small group leading the charge in architecting the agentic workflows and LLM-assisted systems that will allow us to ship Musical Intelligence at 10x the speed of traditional teams.
