Senior Machine Learning Engineer - Content Intelligence

Spotify Spotify · Consumer · London, United Kingdom +1 · Experience

Senior Machine Learning Engineer at Spotify focused on Content Intelligence, responsible for leading end-to-end ML initiatives, designing and deploying large-scale ML systems for audio, text, and visual content. The role involves advancing capabilities in NLU, multimodal AI, and LLM-powered solutions, including RAG and agent orchestration, with a strong emphasis on rigorous evaluation methodologies and productionization.

What you'd actually do

  1. Lead end-to-end machine learning initiatives from ideation and prototyping through experimentation, deployment, and large-scale productionization.
  2. Design, develop, and deploy machine learning systems that operate across hundreds of millions of content signals using both real-time and batch processing architectures.
  3. Advance Spotify’s capabilities in natural language understanding, multimodal AI, and content intelligence.
  4. Build and evaluate LLM-powered solutions using modern prompting techniques, retrieval systems, and advanced model orchestration approaches.
  5. Define rigorous evaluation methodologies including golden datasets, precision and recall frameworks, offline benchmarking, and online experimentation.
