Description

  • Design and build networking systems to stream Unity simulation state to external hosts while balancing bandwidth, latency, convergence, and visual consistency.
  • Invent engine-agnostic synchronization models, including interpolation, prediction, rollback, and distributed authority approaches.
  • Architect a networking stack to synchronize game state between distinct engines and runtime environments.
  • Optimize bandwidth through bit-level serialization, delta compression, and efficient message dispatch.
  • Diagnose and fix end-to-end desynchronization, race conditions, and jitter under real-world network conditions.
  • Work at the intersection of core engine technology, high-performance networking, distributed systems, and graphics.
  • Develop infrastructure for interoperability between real-time 3D runtimes across in-process, cross-process, and networked setups.

Requirements

  • Strong experience with transport layers, reliability, topology design, serialization, and real-time synchronization for high-performance games.
  • Track record shipping scalable multiplayer systems for latency-sensitive games such as FPS, action, MMO, or similar.
  • Experience writing or heavily extending a networking library or netcode system.
  • Experience with large-scale distributed systems such as MMORPGs, cloud gaming, or simulations where synchronization and determinism matter.
  • Strong C++ and C# skills.
  • Comfort capturing raw packets to diagnose timing issues or optimize at the bit level.
  • Fluency with networking models such as authoritative server, deterministic lockstep, and peer-to-peer (preferred).
  • Background with cloud game servers, containerization, and orchestration on GCP, AWS, or Azure (preferred).
  • Experience in network security, encryption, or cheat prevention (preferred).
  • Exposure to Unity DOTS or similar high-performance, data-oriented frameworks (preferred).
  • Sufficient English proficiency for frequent professional verbal and written communication with global colleagues and partners.

Benefits

  • Base salary range of $153,400 to $230,200 USD.
  • Comprehensive health, life, and disability insurance.
  • Employee stock ownership.
  • Competitive retirement and pension plans.
  • Generous vacation and personal days.
  • Support for new parents through leave and family-care programs.
  • Mental health and wellbeing programs and support.
  • Training and development programs.
