Commercial jobs in United Kingdom

At Cast Iron Games, we build technically ambitious games in a calm, focused environment, where every team member has a voice. Based in Tileyard North, we collaborate with high quality partners on high-quality projects, guided by clarity, consistency, and mutual respect.

We’re a young and growing studio, but our team is made up of experienced developers who’ve worked across AAA and independent titles. Together, we’re building a supportive, balanced environment where great work happens without crunch.

As an Experienced Programmer, you'll contribute across multiple areas of a game's development – from game components and runtime tech to tools and performance work. You'll work in complex codebases and be expected to take responsibility for your features, collaborate with other disciplines, and write clear, robust C++ code.

This role is ideal for someone who has already contributed to a shipped title and is ready to deepen their autonomy, technical scope, and cross-discipline awareness.

• Proactive in spotting issues and suggesting solutions
• Communicates clearly and respectfully with peers across disciplines
• Takes feedback well and offers it constructively in return
• Understands that reliable, maintainable code is as important as speed or cleverness

• Experience with graphics programming concepts (materials, shaders, rendering pipelines)
• Familiarity with graphics APIs (e.g. DirectX12, Vulkan)
• Built tools or systems that supported cross-discipline workflows
• Exposure to networking, save systems, or engine-level work
