Job description

About the Role

We are an incubation team inside Lightspeed Studios chasing original IP with high replayability value. We move fast from idea to playable prototype, playtest, and the next idea. This is not a production role – we focus on validating fun, not shipping. The role requires balancing design and code to turn gameplay hypotheses into playable concepts within days, not weeks.

What you’ll do

• Design and prototype gameplay mechanics across genres, focusing on replayability and IP potential.
• Spin up playable web prototypes in Phaser.js / HTML5 / JS – fast, dirty, and instructive.
• Run informal playtests, distill what is fun and what is not, and feed findings back into the next iteration.
• Produce light design documents that communicate intent without overloading detail.
• Collaborate with the design lead on weekly experiments aligned to incubation themes.

Who We Look For

• Hands‑on prototyping skills in Phaser.js, JavaScript, and HTML5 (or a comparable web/lightweight stack).
• A portfolio of personal projects, game jam entries, or school work that shows you can take an idea from concept to playable.
• Strong design instincts – you can articulate why a mechanic feels fun, not just what it does.
• Comfort with ambiguity and rapid iteration; you’re energized by short loops and don’t need a fully written spec to start.
• Curiosity about what makes games replayable – roguelikes, party games, autobattlers, deckbuilders, or any genre.

Bonus Points

• Use of AI‑assisted dev tools (Claude Code, Cursor, Copilot) in your workflow.
• Game jam wins or notable releases on itch.io, Steam, or the App Store.
• Familiarity with replay‑driven systems such as procedural generation, meta‑progression, asymmetric matchmaking, or live‑ops loops.
• Some art, audio, or UX skills to make prototypes feel a notch above a pure programmer build.

Logistics

• Location: Singapore, on‑site at Lightspeed Studios.
• Duration: open – let us know your availability.
• Reports to: Senior Game Designer, Incubation.
