Vertex Break is a Serbian company specializing in game porting & co-development and network development (netcode, server infrastructure, multiplayer protocols) for Steam, PS4/PS5, Nintendo Switch, Xbox and GOG.

We're hiring a Project Manager for the team working on the multiplayer of a popular survival game with a large, active player base, in cooperation with its developer.

The company is based in Belgrade and is opening an office in Novi Sad — we're hiring locally: starting remote, moving to office work as it opens.

Coordinate the engineering team (network code in Java, native C/C++ modules, game logic in Lua) and QA
Be the main point of communication with the external developer partner: scope, status, release schedule and technical alignment
Keep the issue tracker healthy (Jira-style): breakdown, estimation, status tracking
Coordinate the build/release pipeline, multiplayer regression testing, and reproduction/prioritization of network bugs
Manage risks, dependencies and team workload; report progress transparently

Nice to have
