• Scale monetization rails backed by industry heavyweights like Yamaha Music Innovation Fund, impacting the creator economy across music, gaming, and sports.
  
  

What You Will Do

• Lead the end-to-end design and implementation of new features, ensuring the product's look and feel matches its high-stakes functional requirements.
• Architect and build full-stack systems using TypeScript, React, and Node.js, including real-time state management for high-concurrency livestreaming queues.
• Collaborate on technical and visual strategy, leveraging AI-assisted development tools to move from concept to shipped product with extreme velocity.
  
  

The ideal candidate

• Possesses at least 1 year of professional experience with a strong portfolio showcasing high-fidelity frontend work and solid full-stack logic.
• Expert-level proficiency in TypeScript, React, and Node.js, combined with a "design-first" mindset and experience with AI tools like Cursor or Windsurf.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
