We are in the early stages of development on an ambitious, unannounced Strategy / MMO title, creating a team of talented and passionate game makers to join us on this exciting journey!

We are modernizing our backend infrastructure to a gRPC-based services architecture and seeking a skilled and pragmatic Unity networking expert to own the client-side networking integration. This role will be pivotal in ensuring performant, reliable, and scalable communication between the Unity game client and our evolving backend systems.

You will work alongside a team of senior and principal backend engineers dedicated to performance, scalability, and platform improvements, and collaborate with cross-functional client-side teams building game features. Your focus will be implementing and optimizing client-side gRPC communication, designing robust network abstractions, and working with teams to ensure seamless integration with the backend.

What You Will Do

Lead the implementation of gRPC communication within the Unity game client

Design and maintain clean networking abstractions that support multiplayer game features

Collaborate closely with backend engineers to shape protocol design and performance goals

Profile and optimize client-side network performance, memory usage, and latency

Help set best practices and mentor client engineers on networking patterns and technologies

Act as the technical owner for Unity networking, bridge the client-backend boundary during service splits, refactors, and integration.

Contribute to internal tools, debug utilities, and build pipelines to improve developer velocity

What We’re Looking For

Highly experienced in game development with Unity and a focus on networked multiplayer games

Deep experience with client-side networking systems (e.g., gRPC, Protobuf, REST, WebSockets, or custom binary protocols)

Solid understanding of C# performance, async patterns, threading, and Unity architecture constraints

Experience profiling and optimizing network flows in production environments

Ability to work autonomously while coordinating across backend and feature teams

Familiarity with versioned APIs, schema evolution, and compatibility concerns in distributed systems

Bonus Points

Experience with gRPC specifically in Unity (e.g., IL2CPP compatibility, or custom wrappers).

Experience with gRPC in other engines (Unreal, Lumberyard, CryEngine, Custom)

Experience shipping a live service game or working with live operations teams.

Familiarity with microservice architectures and backend deployment pipelines.

Background in gameplay engineering, especially in multiplayer titles.
