Join us as Senior Renderer Developer:
on Supremacy: WW3:
At Twin Harbour Interactive we strive to develop high-quality strategy games and make them accessible for all players around the world. In our eyes game development is a promise for fun and entertainment - that’s what we live and aim for Whether you're an expert tactician or an imaginative world-builder, there's a place here for you to grow, thrive, and leave your mark.

We are looking for an experienced Senior Renderer Developer to join our rendering team in Malta and help shape how hundreds of thousands of players see our world. Supremacy: WW3 is a grand strategy game running in the browser and on mobile on our proprietary WebGL-based renderer, and you will be part of owning that renderer end to end - from the world map and unit rendering down to the shaders themselves.

This is a role with a genuinely open playing field. Our renderer is a mature, battle-tested codebase with a lot of clever engineering in it, and it is now ready for a significant modernisation step:



migrating a legacy WebGL 1 shader library to WebGL 2 and WebGPU, moving to a linear workflow, introducing level of detail and spatial partitioning, and cutting the memory footprint and power consumption on mobile devices. If you like measurable wins - frame times, battery life, memory ceilings, devices supported - you will find plenty of them here.

The renderer is written in JavaScript/TypeScript on top of Three.js and WebGL (GLSL), and connects to a Java game server and a PHP-based API responsible for user management and meta progression. We are API-agnostic by preference: we care much more about your understanding of what the GPU is actually doing than about which APIs or frameworks you have used.

Please submit your resume outlining your relevant experience and why you are interested in joining Twin Harbour Interactive. We look forward to hearing from you
