Who We Are
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 delivering AAA games. Our experienced team has contributed to some of the industry's biggest AAA and independent titles, and we're building a supportive, balanced environment where great work happens without crunch.
We’re now looking for a Lead Programmer, to focus on performance, optimisation, and platform delivery, someone who can guide technical problem- solving, support team growth, and help us ship confidently across multiple platforms.
The Role
As Lead Programmer, you'll guide a small team working within our clients' proprietary engines. You’ll work across codebases to identify performance issues, resolve low-level technical challenges, and lead the team in shipping games that meet platform standards and run smoothly on real hardware.
You'll collaborate with production, QA, art, and other engineers to profile builds, tackle bottlenecks, and ensure we meet platform compliance requirements. You’ll also provide technical leadership, mentoring others, setting quality standards, and ensuring robust code makes it into builds across all platforms.
While the codebases you work with may vary between projects, your role remains constant: lead with clarity, unblock your team, and ensure our contributions are technically excellent and are best of class.
Responsibilities
- Lead feature and systems implementation within bespoke or third-party engine codebases
- Collaborate with production and client teams to plan, scope, and track work
- Break down complex tasks into actionable plans for you and your team
- Review team code, offer constructive feedback, and uphold high quality standards
- Mentor junior and mid-level programmers, supporting their growth and autonomy
- Navigate and improve unfamiliar or undocumented code with confidence
- Investigate and resolve engine-level issues, including performance, memory and stability
- Contribute to internal tools, workflows and in-house tech where needed
- Advocate for sustainable, maintainable solutions and clear documentation
