Lead; Platform Programmer

Cast Iron Games – Tileyard North, Wakefield, UK

Full Time – Onsite

At Cast Iron Games, we deliver technically ambitious, high-quality games with a team-first mindset. Based in the creative heart of Tileyard North, we work on exciting projects with top-tier partners, always with a focus on respect, clarity, and long-term maintainability.

Weʼre now looking for a Lead Programmer to take ownership of technical delivery across projects built in client-owned bespoke engines. This is a hands‑on leadership role for someone who thrives in unfamiliar codebases, enjoys mentoring others, and wants to help bring world‑class games to life across platforms.

As Lead Programmer, youʼll guide a small team working within our clientsʼ 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.

Youʼll collaborate with production, QA, design, 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.

This is an ideal role for someone who loves getting into the weeds of real‑time performance, threading, memory constraints, and platform quirks, but who also enjoys helping others learn, grow, and deliver their best work.

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.
