They are seeking a Senior Machine Learning Engineer to contribute to the design and development of recommendation models that power music surfaces at scale, focusing on improving recommendation quality and collaborating across teams to integrate new signals into the systems.
Responsibilities:
• Contribute to the design, development, evaluation, and iteration of recommendation models — including candidate generation, ranking, and embedding models — powering music surfaces at scale.
• Drive hands-on ML development to improve reward signals and recommendation quality across Home, Now Playing, and other core surfaces.
• Contribute to the team's adoption of generative recommendation models, partnering with ML and AI infrastructure teams.
• Promote best practices in ML systems development, testing, and experimentation within the team.
• Collaborate with Data Science, Product, and Design partners to define success metrics, run A/B experiments, and translate insights into product improvements.
• Partner with teams across Personalization to integrate and test new signals in recommendation systems.
Qualifications:
Required:
• You have a strong background in machine learning and enjoy applying theory to real-world applications, with expertise in statistics and optimization — particularly sequential models, transformers, generative AI, and LLMs.
• You have hands-on experience building and shipping production machine learning systems at scale, ideally in personalization or recommendation systems.
• You have experience implementing ML systems in Java, Scala, Python, or similar languages.
• You have some experience with large-scale distributed data processing frameworks such as Apache Beam, Apache Spark, or Scio, and cloud platforms like GCP or AWS.
• You have experience collaborating across teams on complex ML projects and navigating cross-functional stakeholders.
• You care about agile software processes, data-driven development, reliability, and disciplined experimentation.
