Full Job Description

📋 Description

• We are seeking a Principal Game Engineer to join our growing co-dev team.
• In this role, you will take ownership of the systems players feel most directly: gameplay, UI, 3Cs (character, camera, and controls), and AI.
• Working across a variety of partner projects, you will design, implement, and refine the systems that drive the moment-to-moment experience, bringing expert engineering judgement to everything from input handling and camera behaviour to UI architecture and core gameplay systems.
• As a principal engineer, you will set the technical direction in your area, act as a trusted, customer-facing point of contact for our partners, and raise the bar for quality across the wider team.
• An ideal candidate is passionate about games, has deep experience building player-facing systems in Unreal Engine (or similar), combines expert C++ and C# skills with strong 3D maths, and has a track record of delivering polished, responsive player systems and experiences.
• Player Experience Development: Design, implement, and polish gameplay features, UI systems, and 3Cs (character, camera, and controls) that feel responsive, intuitive, and satisfying in players' hands.
• Technical Leadership: Own the technical direction for player experience work across projects, making sound architectural decisions, anticipating risks, and guiding solutions from prototype through to ship quality.
• Customer-Facing Collaboration: Act as a senior technical representative to our partners, gathering requirements, presenting solutions, communicating trade-offs clearly, and building the trust that underpins great co-development relationships.
• Critical Problem Solving: Apply strong analytical and debugging skills, including profiling and diagnostic tools, to investigate and resolve complex technical issues across gameplay, UI, and engine-level systems.
• Mentorship: Support and mentor engineers across the team, sharing expertise in player experience engineering and helping to grow the studio's capabilities in gameplay, UI, and 3Cs.
• Code Review: Champion high standards of code quality, performance, and maintainability through code reviews, constructive feedback, and by setting the example in your own work.

🎯 Requirements

• Expert Software Engineering: Extensive professional experience developing and shipping games, with the depth of judgement expected at a principal level and a history of delivering high-quality, player-facing systems.
• Strong C++ and C# Skills: Expert proficiency in C++ and C#, with a commitment to writing clean, maintainable, and efficient code.
• Strong 3D Maths: A firm grasp of the linear algebra and geometry that underpin cameras, character movement, animation, and gameplay systems.
• Unreal Engine Skills: Deep experience developing player-facing systems in Unreal Engine, including the Gameplay Framework, UMG/Slate, and input and camera systems. Unreal experience is preferred, though we also value strong Unity backgrounds.

🏖️ Benefits

• Competitive Salary and Benefits Package: Your health and wellbeing is important to us, so we offer a variety of benefits including:
• Hybrid Working Arrangement: Our office in Brighton is located centrally. As a member of our team, you’ll have the flexibility to work at home and collaborate with your fellow team members in person.
