Cast Iron Games – Tileyard North, Wakefield, UK

Full Time – Onsite

At Cast Iron Games, weʼre building technically ambitious games with an experienced, no-nonsense team. Based in Tileyard North, weʼre committed to clarity, quality, and respect in how we work with each other, and in the games we make.

We’re now looking for a Senior Programmer to join our team and take ownership of key systems within client-owned, bespoke engines. This role is ideal for a developer who enjoys navigating unfamiliar codebases, solving tough engineering problems, and mentoring others.

As a Senior Programmer, youʼll work across a variety of systems inside proprietary engines, building new features, improving performance, and unblocking others.
Youʼll be expected to own the implementation of significant features, contribute to technical planning, and act as a source of knowledge and mentorship for less experienced developers.

The engines youʼll work with vary depending on the project, but what stays consistent is your role as a calm, trusted engineer who can dig deep, communicate clearly, and help deliver technically solid, production-ready code.

• Strong proficiency with C++ in large, real-time codebases
• Comfortable working in proprietary game engines
  Ability to quickly understand and work within complex or legacy systems
• Experienced working with performance-critical systems ( multithreading, memory, IO, memory,)
• Familiar with platform-specific considerations (consoles or PC)
• Comfortable using Perforce or similar source control, and task/bug tracking tools such as Jira

• Able to take full ownership of feature delivery, from planning to testing
• Supports others through documentation, pairing, and technical discussion
• Communicates clearly across disciplines — design, production, QA, etc.
• Comfortable raising risks and suggesting practical, team-focused solutions
• Passionate about writing clear, maintainable, production-ready code

• Experience shipping a title built in a bespoke or custom engine

  12, Vulkan)
• Knowledge of online services integration, input handling, or save systems
• Background in technical tooling, automation, or performance tracking
• Exposure to team-based development with external partners or clients

• A people-first studio with a clear focus on craft, clarity, and collaboration
• A high-trust team where experience is valued and voices are heard
• A respectful, experienced team with a strong engineering culture
• The opportunity to ship performance-optimised, cross-platform games youʼre proud of
• Projects that offer real variety. Different game engines, new challenges, constant growth
