Responsibilities

Design and build networking systems to stream Unity simulation state to external hosts while balancing bandwidth, latency, convergence, and visual consistency

Invent new synchronization models from first principles designed to mitigate latency, including engine-agnostic interpolation/prediction/rollback, and distributed authority models

Optimize bandwidth through bit-level serialization, delta-compression, and message dispatch schemes

Diagnose and fix end-to-end desyncs, race conditions, and jitter when two engines disagree about reality under real-world network conditions

Required

Networking Mastery: Transport layers, reliability, topology design, serialization, and realtime synchronization (generalized prediction, rollback, and interpolation) for high-performance games

Engine-Level Netcode: Track record shipping scalable multiplayer systems for latency-sensitive games (FPS, action, MMO, or similar). You haven't just used a networking library—you've written or heavily extended one

Distributed systems experience: Large-scale systems (MMORPGs, cloud gaming, simulations) where synchronization and determinism matter

Low-Level Fluency: Strong C++ and C# skills. Comfortable capturing raw packets to diagnose timing issues or optimize at the bit level

Preferred

Fluency with diverse networking models (authoritative server, deterministic lockstep, peer-to-peer)

Background with cloud game servers, containerization, and orchestration (GCP, AWS, Azure)

Experience in network security, encryption, or cheat prevention

Exposure to Unity DOTS or similar high-performance, data-oriented frameworks
