Job description

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.

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.

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.
• 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.

It’s a really exciting time to join Push Gaming. We’re expanding our teams to deliver some stellar work.

We are passionate about creating premium quality games and will never compromise on this. The approach we take in building and strengthening our team is no different. We set out to attract and retain high performers and are committed to seeking like-minded individuals who share our vision for excellence and quality.

In turn, we offer all the tools and support to allow individuals to grow and thrive, while achieving both personal and company goals in an environment that’s built around trust, collaboration, transparency and accountability.
