The Opportunity

Ironbelly Studios is a team of 20+ gaming veterans who've contributed to franchises including Call of Duty, Halo, Bioshock, PUBG, and Batman across 300+ projects. Now we're building our own competitive multiplayer FPS in Unreal Engine 5—new system architecture from the ground up, not maintenance work.

What You'll Build

Your primary focus: multiplayer systems architecture.

  • Matchmaking systems and dedicated server lifecycle management
  • Netcode optimization for competitive gameplay—hit registration, lag compensation, rewind
  • Replication architecture for complex state: projectiles, physics interactions, game logic

You'll collaborate with the broader team on:

  • Fleet orchestration and global deployment
  • Social systems (parties, friends, voice chat)
  • Backend platform integration (PlayFab/AccelByte/Pragma)
What You Bring

Must-Have:

  • 5+ years working on multiplayer games with C++ and Unreal Engine
  • Hands-on experience with server architecture and matchmaking
  • Strong understanding of replication and netcode for competitive gameplay

Nice-to-Have:

  • Unreal Online Subsystem architecture
  • Competitive or hardcore FPS development background
  • LiveOps and backend platform experience
  • GAS (Gameplay Ability System) in multiplayer contexts
Location

Hybrid in Montreal, Quebec — Collaborate with the team 1-3 days per week at our Basecamp in one of gaming's best cities.

We're building a centralized team here. If you're not local, relocation support available for the right candidate.
