Description

SoundCloud empowers artists and fans to connect and share through music. Founded in 2007, SoundCloud is an artist-first platform empowering artists to build and grow their careers by providing them with the most progressive tools, services, and resources. With over 400+ million tracks from 40 million artists, the future of music is SoundCloud. We are looking for a Senior Engineer to join our Recommendations team. While this is a Backend Engineer role, you’ll work across the full stack and end-to-end systems, from data pipelines to APIs to real-time serving, and everything in between. The Recommendations team ships ML-powered features that connect 200M+ users with music they'll love. We're product engineers who happen to use machine learning - not researchers optimizing metrics in isolation. You'll own features end-to-end: from understanding user needs with Product and Design, to architecting data pipelines processing billions of events, to shipping production systems that balance performance, cost, and user experience.

Python and Go are a Plus. Deep SQL skills for massive datasets (BigQuery, Spark) Cloud platform experience (AWS/GCP) and containerization (Docker, Kubernetes) Familiarity with TensorFlow, PyTorch, or similar frameworks Experience with distributed data processing and ETL pipelines (Airflow, Spark) Understanding of data consistency patterns, eventual consistency, and the trade-offs You can debug issues across multiple systems and data sources About us: We are a multinational company with offices in the US (New York and Los Angeles), Germany (Berlin), and the UK (London) We provide a flexible work culture that offers the opportunity to collaborate and connect in person at our offices as well as accommodating work from home We are deeply committed to ensuring diversity, equity and inclusion at all levels of our organization and fostering a community where everyone’s voice, perspective and experience is respected and heard.
