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, 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.
The Role
As a Senior Unreal Programmer, you'll be a key contributor on our engineering team, trusted to scope, implement, and maintain complex game or engine-level features. You'll collaborate across disciplines, support less experienced developers, and help shape the technical direction of the project through your initiative and experience.
You’ll write clean, performant C++ code and Blueprints and be expected to deeply understand the systems you work on — from replication and architecture to profiling and debugging.
Responsibilities
* Own the development of large systems or features within Unreal 5
* Write clean, maintainable code using both C++ and Blueprints
* Collaborate closely with design, art, and production to ensure implementation aligns with projects goals
* Contribute to planning and task breakdowns with accurate estimates
* Proactively identify technical risks or design issues, and work with leads to resolve them
* Provide mentorship and code reviews for junior and mid-level engineers
* Optimise systems for performance, scalability, and platform constraints
* Write and improve internal documentation, tools, pipelines where needed

Ways of Working

* Proactive in raising blockers, discussing trade-offs and offering solutions
* Supportive of teammates through reviews, pairing and knowledge sharing

Bonus Points
