Unity Multiplayer Engineer

Multiplayer is where most solo and small-team Unity projects quietly stall, Netcode for GameObjects, server authority, and client-side prediction all have to work together correctly or players see rubber-banding, desync, or outright cheating within the first week of launch. We build the networking layer on Netcode for GameObjects with Unity Relay/Lobby for matchmaking, implement server-authoritative gameplay so clients can't cheat obvious things like position or health, and tune client prediction and reconciliation so the game feels responsive despite real-world latency. Teams come to us with a working single-player build and no idea how to safely add multiplayer, or with an existing multiplayer implementation that desyncs under real network conditions. We test against actual latency and packet loss, not just two machines on the same LAN.

This is a capability we deliver for you as a service, not a role we’re hiring for.

How We’d Approach This

A clear, staged plan, not a black box

These are the service-specific steps inside our six-step process.

1
Review the gameplay systems that need to go multiplayer and flag which ones need server authority versus which are safe to trust the client on.
2
Build a Relay/Lobby-connected multiplayer pilot for one core mechanic and stress-test it under simulated latency and packet loss.
3
Review desync and cheat-surface findings with your team before wiring up the remaining gameplay systems.
4
Roll networking out across the full game with monitoring for desync and abnormal client behavior post-launch.
