👋 About the role

We’re looking for a hands-on game developer. You’ll help us build a library of games that attract players, keep them coming back and shape the identity of the Jamango! Ecosystem.

Your work will also become a major part of how other people create, because everything you build will be remixable and reusable through Jamango’s creation tools and AI agent workflows. 

You’ll be responsible for creating fun, performant gameplay systems that power great games today and raise the floor and ceiling of hundreds of thousands of creations across Jamango in the years to come.

🧱 What you’ll do
  • Take games from concept through prototyping, launch and ongoing updates, balancing frequent releases with quality gameplay on mobile and desktop.

  • Iterate quickly and get playable ideas in front of players early, act on feedback and keep improving controls, game feel and progression.

  • Create mechanics and systems that become useful foundations for creators and AI agents across Jamango.

  • Understand what makes popular games work and bring your own creative take to emerging trends, both on other platforms and within Jamango.

  • Work with Product & Live Ops on content, events and updates that build engagement and community.

  • Work with our engineering and art team, use AI throughout your workflow and help shape Jamango’s creation tools through hands-on use and feedback.

✨ You are
  • A hands-on game maker with a strong understanding of game design and experience making games before.

  • Someone who loves making things feel great to play, from responsive controls and satisfying feedback to gameplay that keeps people coming back.

  • Fast, resourceful and comfortable taking ownership, keeping scope manageable and making things happen.

  • Curious about trends and creative enough to be able to turn inspiration into something with its own character.

  • Excited about using AI to build more, move faster and make better games.

  • Someone who playtests often and uses player feedback and data alongside their own instinct for what’s fun.

  • A clear communicator who takes feedback well and enjoys working closely with builders, artists and engineers.

  • Thoughtful about performance and reusability, creating gameplay that gives other creators something solid to build on.

  • Passionate about building a social gaming platform for young people and making game creation more accessible.

  • Bonus points for experience making browser or Roblox games, or building reusable multiplayer gameplay systems.

🚀 Why join us?
  • You’ll take real ownership of making Jamango games and help define what games across the ecosystem look and feel like.

  • You’ll move fast, ship games and see your work make an impact in the hands of a growing community of real players.

  • Your gameplay will become building blocks for other creators, giving your work an impact far beyond the games you ship.

  • You’ll work closely with a small, tight team of experienced founders, builders, artists and engineers who love what they do to build cool stuff and have fun doing it.

  • Competitive salary and stock options.

  • Twice-a-year team offsites.

  • WFH budget so your space feels like yours.
