    Description

    THE MISSION


    Build the backend that powers thousands of concurrent battles in our next-generation competitive FPS. This isn't web development with game features - this is architecting the real-time infrastructure that hardcore players demand: sub-50ms response times, bulletproof persistence, and flawless matchmaking for a title that will compete with CS2 and Valorant.

    WHY THIS ROLE MATTERS


    You won't be building CRUD APIs. You'll own the entire competitive integrity of our game:

    • Player Trust: Your persistence layer holds millions in virtual items
    • Match Fairness: Your matchmaking determines every player's experience
    • Live Operations: Your systems handle 10,000 concurrent matches without breaking a sweat

    YOUR TECHNICAL BATTLEFIELD


    Mission-Critical Systems You'll Own:

    • Stateful Game Services: Design distributed systems managing real-time game state across thousands of concurrent matches
    • High-Performance Matchmaking: Build ELO-based matchmaking supporting 50,000+ concurrent players with <5 second queue times
    • Inventory & Economy Backend: Architect transactional systems managing player inventories worth real money
    • Anti-Cheat Integration: Implement server-authoritative validation and integrate with BattlEye/EAC
    • LiveOps Infrastructure: Build hot-patching systems for zero-downtime updates during peak hours

    Your Arsenal:

    • Game-Specific: PlayFab/Pragma/AccelByte or custom equivalents
    • Infrastructure: Kubernetes orchestrating 1000+ pods, AWS GameLift/Agones
    • Performance: Redis for session state, PostgreSQL for persistence, 100K+ ops/second
    • Protocols: WebSockets, gRPC for service mesh, UDP for game traffic
    • Monitoring: Real-time observability handling 1M+ events/minute

    REQUIRED EXPERTISE


    Non-Negotiable Technical Skills:

    • 5+ years shipping multiplayer game backends (not web apps that happen to be games)
    • Proven scaling experience: You've handled 50K+ CCU in production
    • Battle-tested with: PlayFab, Pragma, AccelByte, or built similar from scratch
    • Deep knowledge: Kubernetes at scale, AWS game services, NodeJS performance optimization
    • Game-specific expertise: Tick rates, client prediction, lag compensation, state synchronization

    Evidence We Need:

    • Shipped titles you can point to on Steam/Epic/Console
    • War stories about scaling failures and how you fixed them
    • Specific metrics: CCU handled, latency achieved, uptime maintained
    • Your approach to common problems: inventory duplication, match state corruption, DDOS mitigation

    BONUS MULTIPLIERS

    • Direct Unreal Engine 5 replication system experience
    • Contributions to GDC talks or technical game blogs
    • Experience with competitive game ranking systems (ELO, TrueSkill)
    • Background in anti-cheat or game security

    THE GAME YOU'LL POWER


    We're building the competitive FPS that PC players have been waiting for. Think CS:GO's competitive integrity meets modern gameplay. Your backend will be the difference between "another shooter" and "the next decade's esport."

    LOCATION


    Hybrid role based in Montreal, Quebec. Exceptional candidates in Canada may be considered but local candidates will be prioritized.
