Job Details

We’re looking for a Principal Core Tech Engineer to set the technical bar for our engineering team. This isn’t about managing people, it’s about solving the hardest problems, pushing Unreal Engine 5 to its limits, and making sure our tech is rock solid, scalable, and ready for war.

You’ll be deep in the engine, working on bleeding-edge UE5 systems — replication, streaming, threading, ECS, and more. This is not a role for someone who wants to stay in the safe lane. We need someone who thrives in uncharted territory and isn’t afraid to break things, figure it out, and build something better.

What you'll be doing

  • Own and refine the foundation of our game systems in Unreal Engine 5
  • Drive optimisation and debugging across all core tech areas
  • Define best practices for system architecture, memory management, threading, networking, and scalability
  • Guide the engineering team through technical challenges and architectural decisions
  • Proactively identify performance bottlenecks and solve them at the engine level
  • Collaborate closely with Production, Design, and Art to keep systems clean, usable, and future proof

What we’re looking for

  • 5+ years of professional experience in games
  • Deep knowledge of C++ and Unreal Engine 5 (especially the gameplay framework, ECS, replication, and threading)
  • A track record of solving high-risk technical problems on shipped multiplayer games
  • Strong understanding of multiplayer networking and netcode optimisation
  • Clear communication, pragmatic thinking, and a mindset of ownership
  • Passion for games and the tech behind them
  • Confidence working with cutting edge UE5 systems — even when the documentation’s thin and no one’s done it before

The Game

You'll be working on Wardogs, an all-out-warfare multiplayer first person shooter. That means infantry combat, tank warfare, jet dog fighting, and artillery barrages. We play test the game twice a week, so you'll have lots of time to get stuck in and really be a part of the game you're creating.
