GLADIATOR GAMES STUDIO

Lead AI Game Engineer
London / Hybrid

up to £140,000

We build real-money HTML5 slot games with a small, senior team. We use AI as a core part of how we develop not as an experiment, but as a genuine workflow.
THE ROLE
You'll lead development of our next generation of slot games. Hands-on technical leadership, you're still writing code. You'll help define how AI-assisted workflows get built into the studio's process, and mentor a small team of strong engineers.
Prior Slot Game Development Experience Is Non-negotiable.
WHAT YOU'LL WORK ON

Lead development of new slot game titles from concept to production
Build core game systems and reusable frameworks in JS/TS
Prototype and ship quickly using AI-assisted development loops
Collaborate directly with designers and product to turn ideas into playable games
Mentor and help grow the engineering team

Required

Slot game experience - real-money or social casino platforms (essential)
Strong JavaScript / TypeScript
HTML5 game development
Rendering frameworks - PIXI.js, Phaser, or similar
Comfortable using AI coding tools day-to-day (Claude Code strongly preferred)
Strong architectural and system design thinking
Able to ship production, quality software at pace

NICE TO HAVE

Familiarity with slot mechanics - reels, paylines, bonus systems, RNG
Experience with slot math models, RTP, or volatility design
Experience building reusable game engines or frameworks

SET UP
Team - Small, senior no bloat
