Game Client Developer
Push Gaming is a dynamic and innovative game development studio specialising in creating top-quality, mobile-optimised online casino games. With a passion for gaming and a commitment to pushing boundaries, we are dedicated to delivering exceptional experiences to players worldwide.
Role purpose:
We are looking for a mid-level Game Client Developer who will implement and maintain the front-end of the team's slot titles - gameplay, interfaces, and visual functionality - on the studio's shared framework and game template, across both new titles and family clones/reskins, with technical stability and performance. As a mid-level dev, you will be self-sufficient on a whole feature or component end-to-end within the team, handling edge cases without step-by-step guidance. The step up from Junior is autonomy on scoped work.
Location: hybrid in London.
Key Responsibilities (including but not limited to):
- Develop, maintain, and optimise front-end game features, UI elements, and visual effects on the shared framework and game template.
- Implement game logic within the engine/framework. The client renders an outcome that is determined by the server.
- Build clones and reskins as thin overlays over their family base - never changing the base contract; flag anything that seems to require a base change instead of working around it.
- Debug, test, and resolve client-side issues across devices and platforms; work with QA on defects and inconsistencies, and with artists/animators and game designers on per-title integration.
- Participate in peer review; contribute to reusable components and tooling; raise cross-cutting needs through the team's framework intake route rather than patching the shared layer locally.
- Maintain rendering literacy: draw calls, sprite batching, texture atlases.
- Follow coding standards, version control practices, and the team's development workflow, delivering against the games roadmap and its priorities.
- Any other task/responsibility which may be related and/or connected to the role of Game Client Developer.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Success in the first 3 months: Own a feature from start to release without step-by-step guidance; deliver a clone or reskin as a thin overlay without breaking its family base; hold the performance budget on real devices.
What you'll bring to the role:
- 2+ years of professional experience in client-side game development or a related role.
- Strong proficiency in JavaScript/TypeScript; experience with a game engine or framework (PixiJS, Phaser, Unity).
- Object-oriented programming and design patterns; debugging, performance optimisation, and Git.
- A good grasp of game architecture, UI implementation, and asset integration; comfortable building on a shared codebase they consume rather than own.
- Strong problem-solving skills and attention to detail; effective collaboration on cross-functional teams.
- Experience with slot or iGaming development is highly desirable; familiarity with atlas/spritesheet pipelines is a plus.
