The Role

Our client is hiring a founding engineer to help build production-ready ML systems that power the next generation of music learning for a large and growing base of musicians. You'll work closely with the Head of AI, taking abstract ideas and turning them into rock-solid, shipped implementations. Prior music-AI experience is not expected — the team already has domain experts and is looking for exceptional general technical ability paired with a startup mindset.

What You'll Be Doing

• Building and shipping ML models for audio and symbolic music understanding into production systems used by real musicians
• Translating the research team's ideas into solid, working engineering implementations
• Partnering with data, design, and product to integrate models into user-facing features
• Curating, preprocessing, and building pipelines around large-scale music datasets
• Contributing to model evaluation, optimization, and deployment for real-world latency and reliability
  
  
  

Tech stack: Python, PyTorch / JAX, large-scale ML systems

Requirements

• Zero to four years of experience in ML engineering, infrastructure, or a comparably demanding technical role
• Time at a company known for a high technical bar — for example, big-tech infrastructure, quant, or a fast-scaling startup
• Strong software engineering and hands-on coding ability

• Working proficiency with modern ML frameworks such as PyTorch or JAX
• The ability to take research concepts and turn them into robust, shippable code
• A collaborative working style that meshes well with researchers and fellow engineers
• Based in San Francisco (or ready to relocate) and comfortable working in person for the majority of the week
  
  
  

Nice to Haves

• Prior experience at a startup or other early-stage company
• Exposure to audio, sequence modeling, or generative model domains
• Experience building data pipelines or working with large-scale datasets
