You will work on Link Legends (https://play.google.com/store/apps/details?id=com.ObscureGames.LinkMasters&hl=en), a PvP Match3 game currently in soft-launch. Take ownership of architecting and delivering high-performance, scalable multiplayer gameplay systems and backend infrastructure for competitive and cooperative online experiences.

If you live and breathe deterministic rollback, predictive movement, and low-latency responsiveness — and you’re ready to push Photon Fusion 2 to its limits — we want you on board.

• Collaborate closely with gameplay engineers and designers to define and build real-time networked mechanics.
• Work with DevOps to deploy and maintain scalable, secure server infrastructure.
• Profile and optimize networking performance to ensure ultra-responsive player experiences.
• Document systems and mentor other developers in best practices for multiplayer and backend architecture.
• Support live multiplayer features post-launch with diagnostics, analytics, and troubleshooting tools.

Requirements

• 5+ years of professional experience in Unity game development.
• Proven experience with Photon Fusion 2 in a production environment.
• Deep understanding of authoritative server models, client prediction, lag compensation, and rollback.
• Solid backend experience using Node.js, .NET, or equivalent.
• Familiarity with cloud platforms like AWS or Azure.
• Experience shipping and maintaining live multiplayer games.
• Excellent debugging skills and a performance-oriented mindset.
• Strong communication and teamwork abilities.

Nice to Have

• Experience with matchmaking systems (ELO, MMR, skill-based).
• Knowledge of PlayFab, or similar backend-as-a-service platforms.
• Familiarity with CI/CD pipelines and live deployment workflows.
• Experience in Unity ECS or DOTS for performance-heavy projects.
• Enthusiasm for competitive or real-time multiplayer games.
