Senior Unreal UI Engineer | Multiplayer FPS
About the role
THE PROJECT
Build UI systems that maintain 144+ FPS while handling real-time combat data for thousands of concurrent players.
Join the creators of Call of Duty, Halo, and Bioshock along side the Ironbelly Studios team in Montreal. We're crafting an extraction shooter that pushes Unreal Engine 5 to its absolute limits - where every millisecond of UI rendering impacts competitive outcomes.
You Will Own
- Performance-Critical Architecture: Design UI systems in UE5's UMG that handle intense multiplayer combat without dropping a single frame
- Real-Time HUD Systems: Build server-authoritative HUD elements with client prediction for zero-latency competitive play
- Complex Interactive Systems: Craft real-time inventory, loadout customization, and spectator modes that feel instant
- Systems Integration: Connect UI seamlessly with weapon mechanics, AI state machines, and persistent player progression
- Innovation Layer: Pioneer interfaces for player-owned economies and comprehensive creator tools
- Rapid Iteration Tools: Build workflows that let our team iterate at the speed of player feedback
Requirements
- 5+ years UI programming in game development
- Expert knowledge of Unreal Engine 5's UMG system and UI architecture patterns
- Strong C++ programming with proven UI system implementation
- Extensive Blueprint visual scripting for UI logic and data binding
- 2+ shipped titles (commercial games or major live-service updates)
- Proven experience with UI performance optimization and memory management
You'll Stand Out With
- Competitive FPS/extraction shooter UI experience
- Multiplayer UI synchronization expertise
- Platform certification experience (PC/Console)
- UI automation frameworks and analytics integration
- Localization system implementation
Web3 experience interesting but not required - we'll teach you the blockchain side
Why This Role Is Different
The Technical Challenge: This isn't another battle royale UI. You'll architect systems handling player-owned economies, real-time market data, and creator tools - all while maintaining the frame-perfect responsiveness hardcore FPS players demand.
The Impact: Shape how millions experience true digital ownership in gaming. Your interfaces will define the standard for the next generation of player-empowered experiences.
What We Offer
- Hybrid flexibility: Collaborate in our Montreal studio 1-2 days/week, deep work from home
- 15+ years of battle-tested expertise in AAA development
- Direct impact: Your work ships to players, not committees
- Growth trajectory: Define UI standards for an entirely new game economy model
Location
Montreal, Quebec - Hybrid model with in-office collaboration 1-2 days per week.
Priority given to Montreal-based candidates. Relocation support available for exceptional fits.
