Machine Learning Engineer - Content Discovery
AI in this role
Design and deploy scalable recommendation and ranking machine learning models for music discovery at Suno.
We're building the world's first creative entertainment platform, where the entire world can feel the joy and fulfillment of making music. Music is for everyone: Our users include everyone from grandmothers creating songs for their loved ones, to Grammy winners using Suno Studio, our power tool, to make the most popular hits in the world.
Building the future of entertainment requires ambition. The pace is fast, the problems are hard, and the work demands ownership and intensity. For the right people, it’s incredibly rewarding: a chance to shape a new medium, work with a small team that cares deeply about quality, make music, drink too much coffee, and build something that millions of people use to express themselves in ways that were never before possible.
Suno is the fastest growing consumer entertainment company and the leader in AI music. We are backed by leading investors including Bond Capital, Menlo Ventures, Lightspeed Venture Partners, IVP, Forerunner, Union Square Ventures, Alkeon, Quiet, Matrix Partners, Schroders Capital and, NVentures (venture arm of NVIDIA).
About the Role
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.
Machine Learning Recommendations Engineer Song Description
What You’ll Do
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
What You’ll Need
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
Additional Notes: Applicants must be eligible to work in the US.

Skills and AI tools this role asks for
Questions you could be asked
- Tell me about a project where machine learning was part of your work. What did you do?
- Tell me about a project where recommendation systems was part of your work. What did you do?
- Tell me about a project where mathematical modeling was part of your work. What did you do?
- Tell me about a project where personalization was part of your work. What did you do?
- Walk me through how you've used PyTorch in your day-to-day work.
Adapt your resume
- List these exact terms on your resume: Machine Learning, Recommendation Systems, Mathematical Modeling, Personalization, and PyTorch. An applicant tracking system matches the wording, not the idea.
- Attach one line of real, concrete experience to at least one of them — a tool named with nothing behind it rarely survives a human read.
- Lead with what you built, trained or shipped — this role is judged on the AI system itself, not the tools around it.
