Posting language: English · French
Posted: Sep 2, 2026

Original job description

English section of this bilingual listing.

⚡ 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 work on advances and highly orchestrated backend features of our games. You will be building CRUD APIs often!

Ecosystem Impact: Your code will power a new era of virtual economies
Live Operations: Your systems will handle thousands of concurrent user actions

🔧 YOUR TECHNICAL BATTLEFIELD

Mission-Critical Systems You'll Own:

Stateful Game Services: Design distributed systems managing real-time game state across thousands of concurrent users
Inventory & Economy Backend: Architect transactional systems managing player inventories worth real money
Advance Features: Orchestrate features related to player actions

Your Arsenal:

Infrastructure: Kubernetes for scalable service architecture
Performance: Redis for caching, PostgreSQL for persistence, 100K+ ops/second
Protocols: WRESTful services, Typescript, Distributed systems orchestration framework (virtual actor frameworks, queuing)
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

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
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."

🎮 THE GAME YOU'LL POWER

📍 Location

Hybrid role (1-3 days in office) based in Montreal, Quebec.

⚡ LA MISSION

Construisez le backend qui alimentera des milliers de batailles simultanées dans notre FPS compétitif de nouvelle génération. Il ne s'agit pas de développement web avec des fonctionnalités de jeu, mais bien de concevoir l'infrastructure en temps réel exigée par les joueurs hardcore : des temps de réponse inférieurs à 50 ms, une persistance à toute épreuve et un matchmaking sans faille pour un titre qui rivalisera avec CS2 et Valorant.

🏆 POURQUOI CE POSTE EST IMPORTANT

Vous ne développerez pas d'API CRUD. Vous serez responsable de l'intégrité concurrentielle de notre jeu dans son ensemble :
Confiance des joueurs : votre couche de persistance contient des millions d'objets virtuels
Équité des matchs : votre système de matchmaking détermine l'expérience de chaque joueur
Opérations en direct : vos systèmes gèrent 10 000 matchs simultanés sans aucun problème

🔧 VOTRE CHAMP DE BATAILLE TECHNIQUE

Systèmes critiques dont vous serez responsable :
Services de jeu avec état : concevoir des systèmes distribués gérant l'état du jeu en temps réel sur des milliers de matchs simultanés
Matchmaking haute performance : créer un matchmaking basé sur l'ELO prenant en charge plus de 50 000 joueurs simultanés avec un temps d'attente inférieur à 5 secondes
Backend d'inventaire et d'économie : concevez des systèmes transactionnels gérant les inventaires des joueurs ayant une valeur monétaire réelle
Intégration anti-triche : implémentez une validation autoritaire du serveur et intégrez-la à BattlEye/EAC
Infrastructure LiveOps : créer des systèmes de correctifs à chaud pour des mises à jour sans interruption pendant les heures de pointe
Votre arsenal :
Spécifique au jeu : PlayFab/Pragma/AccelByte ou équivalents personnalisés
Infrastructure : Kubernetes orchestrant plus de 1 000 pods, AWS GameLift/Agones
Performances : Redis pour l'état de session, PostgreSQL pour la persistance, plus de 100 000 opérations/seconde
Protocoles : WebSockets, gRPC pour le maillage de services, UDP pour le trafic de jeu
Surveillance : observabilité en temps réel gérant plus d'un million d'événements/minute

✅ COMPÉTENCES REQUISES

Compétences techniques indispensables :

Plus de 5 ans d'expérience dans le développement de backends pour jeux multijoueurs (et non d'applications web qui se trouvent être des jeux)
Expérience avérée en matière de mise à l'échelle : vous avez géré plus de 50 000 CCU en production
Expérience éprouvée avec : PlayFab, Pragma, AccelByte, ou développement similaire à partir de zéro
Connaissances approfondies : Kubernetes à grande échelle, services de jeux AWS, optimisation des performances NodeJS
Expertise spécifique aux jeux : taux de tick, prédiction client, compensation de latence, synchronisation d'état

Preuves requises :

Titres commercialisés que vous pouvez citer sur Steam/Epic/Console
Récits d'échecs en matière de mise à l'échelle et de la manière dont vous les avez résolus
Indicateurs spécifiques : CCU gérés, latence atteinte, disponibilité maintenue
Votre approche des problèmes courants : duplication d'inventaire, corruption de l'état des matchs, atténuation des attaques DDOS

🚀 MULTIPLICATEURS DE BONUS

Expérience directe du système de réplication Unreal Engine 5
Expérience des systèmes de classement compétitifs (ELO, TrueSkill)
Expérience dans la lutte contre la triche ou la sécurité des jeux

🎮 LE JEU QUE VOUS ALLEZ DÉVELOPPER

Nous développons le FPS compétitif que les joueurs PC attendent depuis longtemps. Imaginez l'intégrité compétitive de CS:GO associée à un gameplay moderne. Votre backend fera la différence entre « un autre jeu de tir » et « l'e-sport de la prochaine décennie ».

📍 Lieu

Poste hybride (1 à 3 jours au bureau) basé à Montréal, au Québec.
