Machine Learning Engineer

Who you are

• Strong background in applied mathematics, statistics, machine learning, or a related quantitative field (PhD or equivalent experience)
• Experience designing models from first principles (e.g., probabilistic models, optimization-based systems, representation learning, graph-based methods)
• Proficiency in Python and modern ML frameworks (e.g., PyTorch) with the ability to implement and iterate on research ideas
• Familiarity with learning from user interaction data (implicit feedback, ranking losses, bandits, or reinforcement-learning-adjacent methods)
• Comfort reasoning about tradeoffs between model quality, scalability, and system constraints
• Curiosity, rigor, and a desire to understand systems deeply rather than treating models as black boxes
• A love of music (listening, exploring, or making) is a strong plus

What the job involves

• We’re looking for early members of our machine learning recommendations team. You’ll work closely with the founding team and have ownership of a wide variety of technical decisions on how we build and deploy our state of the art recommendation models
• Formulate and develop mathematical models of user preference, similarity, and engagement for music discovery
• Design learning systems that infer user taste from sparse, noisy, and evolving interaction data
• Build and deploy scalable recommendation and ranking models that operate under real-time latency and throughput constraints
• Translate abstract objectives (relevance, novelty, diversity, long-term satisfaction) into measurable metrics and optimized systems
• Run large-scale experiments and causal analyses to evaluate model behavior and product impact
• Work closely with product and research leadership to define the technical direction of Suno’s personalization systems
