⚡ 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

đź”§ 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

âś… 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

  • 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."

⚡ LA MISSION

Construisez le backend qui alimentera des milliers de batailles simultanées dans notre FPS compétitif de nouvelle génération.

🏆 POURQUOI CE POSTE EST IMPORTANT

  • Vous ne dĂ©velopperez pas d'API CRUD. Vous serez responsable de l'intĂ©gritĂ© concurrentielle de notre jeu dans son ensemble :

  • Confiance des joueurs : votre couche de persistance contient des millions d'objets virtuels

  • ÉquitĂ© des matchs : votre système de matchmaking dĂ©termine l'expĂ©rience de chaque joueur

  • OpĂ©rations en direct : vos systèmes gèrent 10 000 matchs simultanĂ©s sans aucun problème

đź”§ VOTRE CHAMP DE BATAILLE TECHNIQUE

  • Systèmes critiques dont vous serez responsable :

  • Services de jeu avec Ă©tat : concevoir des systèmes distribuĂ©s gĂ©rant l'Ă©tat du jeu en temps rĂ©el sur des milliers de matchs simultanĂ©s

  • Matchmaking haute performance : crĂ©er un matchmaking basĂ© sur l'ELO prenant en charge plus de 50 000 joueurs simultanĂ©s avec un temps d'attente infĂ©rieur Ă  5 secondes

  • Backend d'inventaire et d'Ă©conomie : concevez des systèmes transactionnels gĂ©rant les inventaires des joueurs ayant une valeur monĂ©taire rĂ©elle

  • IntĂ©gration anti-triche : implĂ©mentez une validation autoritaire du serveur et intĂ©grez-la Ă  BattlEye/EAC

  • Infrastructure LiveOps : crĂ©er des systèmes de correctifs Ă  chaud pour des mises Ă  jour sans interruption pendant les heures de pointe

  • Votre arsenal :

  • SpĂ©cifique au jeu : PlayFab/Pragma/AccelByte ou Ă©quivalents personnalisĂ©s

  • Infrastructure : Kubernetes orchestrant plus de 1 000 pods, AWS GameLift/Agones

  • Performances : Redis pour l'Ă©tat de session, PostgreSQL pour la persistance, plus de 100 000 opĂ©rations/seconde

  • Protocoles : WebSockets, gRPC pour le maillage de services, UDP pour le trafic de jeu

  • Surveillance : observabilitĂ© en temps rĂ©el gĂ©rant plus d'un million d'Ă©vĂ©nements/minute

✅ COMPÉTENCES REQUISES

Compétences techniques indispensables :

  • Plus de 5 ans d'expĂ©rience dans le dĂ©veloppement de backends pour jeux multijoueurs (et non d'applications web qui se trouvent ĂŞtre des jeux)

  • ExpĂ©rience avĂ©rĂ©e en matière de mise Ă  l'Ă©chelle : vous avez gĂ©rĂ© plus de 50 000 CCU en production

  • ExpĂ©rience Ă©prouvĂ©e avec : PlayFab, Pragma, AccelByte, ou dĂ©veloppement similaire Ă  partir de zĂ©ro

  • Connaissances approfondies : Kubernetes Ă  grande Ă©chelle, services de jeux AWS, optimisation des performances NodeJS

  • Expertise spĂ©cifique aux jeux : taux de tick, prĂ©diction client, compensation de latence, synchronisation d'Ă©tat

Preuves requises :

  • Titres commercialisĂ©s que vous pouvez citer sur Steam/Epic/Console

  • RĂ©cits d'Ă©checs en matière de mise Ă  l'Ă©chelle et de la manière dont vous les avez rĂ©solus

  • Indicateurs spĂ©cifiques : CCU gĂ©rĂ©s, latence atteinte, disponibilitĂ© maintenue

  • Votre approche des problèmes courants : duplication d'inventaire, corruption de l'Ă©tat des matchs, attĂ©nuation des attaques DDOS

🚀 MULTIPLICATEURS DE BONUS

  • ExpĂ©rience directe du système de rĂ©plication Unreal Engine 5

  • ExpĂ©rience des systèmes de classement compĂ©titifs (ELO, TrueSkill)

  • ExpĂ©rience dans la lutte contre la triche ou la sĂ©curitĂ© 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 ».
