About the Role
We are developing a third-person competitive shooter in Unreal Engine 5, currently in beta testing, with a strong focus on online multiplayer systems and long-term live operations.
This role focuses on integrating gameplay-facing online systems and platform services into the game client. You will work on systems such as matchmaking, player parties, clans, social features, platform integrations, account flows, and other online meta-features that connect the game client with backend infrastructure.
You will collaborate closely with gameplay programmers, backend engineers, UI/UX designers, and platform teams while working within an existing large-scale UE5 production environment.

Hands-on experience integrating live-service meta systems such as:

Additionally:
- Experience debugging and maintaining online systems in production
- Familiarity with Steam and console platform services
- Understanding of asynchronous/networked architecture in games
- Experience working within existing multi-team codebases
