Flutter Developer (Gaming)

bout Jackpot Technologies Jackpot Technologies is a fast-growing company in the online gaming sector. We operate jackpot.studio, our B2B games division that builds in-house games and licenses them to casino operators globally. Our portfolio includes classics like Dice, Blackjack, and Plinko, and originals like Top Dollar, Dr Pump, and Cases.

We are a small, agile team that moves quickly and takes real pride in our work. Every game that ships carries our name, which means craft and follow-through are paramount.

The role Casino games live or die on feel, and on mobile, feel is everything. You will build real games in Flutter, from the core loop and the reels to the win sequences, the particle FX, and the exact moment a payout lands.

These are native games we license to operators worldwide, so they have to run buttery smooth on every device, hold a rock-solid 60fps, and feel as good as anything in the store. You will care as much about timing, easing, and frame budgets as you do about clean code. A win should feel like a win.

What You Will Do

• Build casino games end to end in Flutter: game loop, rendering, state, math integration, and UI.
• Bring mechanics to life with precise timing and feel, from slot reels and multiplier curves to card, dice, and wheel games.
• Build the juice: win animations, particle FX, screen transitions, and big-win celebrations.
• Integrate game math, RNG, and real-time outcomes from our backend, with deterministic, verifiable results.
• Hit 60fps on a wide range of devices. Profile and optimize render time, memory, battery, and load times.
• Implement responsive layouts across portrait and landscape, phone and tablet, with multi-language and multi-currency support.
• Drop into custom rendering (Flame, CustomPainter, canvas, or shaders) when the widget tree is not enough.
• Partner with artists, animators, designers, and backend so each game ships as one polished piece.
• Build reusable systems and a shared game framework so the next title ships faster.

What You Will Bring

• 3+ years building production mobile apps or games, with real Flutter and Dart depth and titles you have shipped to both stores.
• A strong grasp of game loops, frame timing, and rendering performance.
• Hands-on experience with a rendering or game layer: Flame, CustomPainter, canvas, or shaders.
• Animation chops: implicit and explicit animation, Rive or Lottie, and skeletal animation (Spine) a plus.
• Solid architecture and state management (Riverpod, Bloc, or similar) that scales across many titles.
• Fluency with async Dart, isolates, and performance profiling using DevTools and frame analysis.
• Real-time integration: websockets, deterministic outcomes, and graceful reconnection.
• A real respect for timing. You can explain why your 18-frame easing feels better than the 12-frame version.
• Fluent with modern AI coding tools (Copilot, Claude, Cursor) in your daily workflow. You use them to move faster without sacrificing quality or control.
• A fast, reliable production cadence. You plan your work, hit your dates, and do not leave messes for the next person.

Bonus points

• Built slot or casino games before, and understand RTP, volatility, and certification constraints.
• Game math, RNG, or remote game server (RGS) integration experience.
• Spine, DragonBones, or Rive skeletal animation exported into a live product.
• Native iOS (Swift) or Android (Kotlin), and shader or GLSL work.
• Unity or another game engine in your background.
• Sound-led animation instincts. You animate to audio and it shows.
• Built a shared game framework or design system that sped up a whole team.

Tools you will work with Daily: Flutter, Dart, Flame, Figma, Git

Often: Rive, Lottie, Spine, REST and websockets, Xcode, Android Studio

Bonus: Swift, Kotlin, shaders / GLSL, Unity, DragonBones
