Spotify - Staff Machine Learning Engineer Staff Machine Learning Engineer London / Stockholm Engineering Personalization / Permanent / Remote

The role requires a strong background in machine learning with expertise in statistics and optimization, particularly in sequential models, transformers, generative AI, and large language models, including relevant fine-tuning processes. Candidates must have hands-on experience with large, cross-collaborative machine learning projects and stakeholder management. Experience implementing production machine learning systems at scale using languages like Java, Scala, or Python is necessary, with specific requirements for PyTorch, Ray, and Hugging Face. Familiarity with large-scale distributed data processing frameworks such as Apache Beam, Apache Spark, or Scio, and cloud platforms like GCP or AWS is also needed. A commitment to agile software processes, data-driven development, reliability, and disciplined experimentation is valued.
