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

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

Proficiency in C++, Blueprints, and Unrealʼs component-based architecture

Understanding of replication, memory/performance profiling, and debugging workflows
Able to balance short-term priorities with long-term code maintainability
Comfortable using Perforce or similar source control, and task/bug tracking tools such as Jira
Ways of Working
Comfortable working independently, scoping and delivering complex features
Proactive in raising blockers, discussing trade-offs and offering solutions
Supportive of teammates through reviews, pairing and knowledge sharing
Communicates clearly with both technical and non-technical collaborators
Passionate about quality, clarity and making others more effective
Bonus Points
Familiarity with AI, animation systems, or physics frameworks in Unreal 5
