The opportunity

The team that brought Unity to visionOS and enabled real-time interaction via Play-to-Device is growing in preparation for something even more ambitious: adapting PolySpatial to stream Unity content into other game engines and 3D environments—in-process, cross-process, and over the network.

We're looking for engineers eager to help us invent how different real-time 3D runtimes communicate and render under real-world constraints. You’ll work at the intersection of core engine tech, high-performance networking, distributed systems, and graphics. This is your opportunity to build the fundamental infrastructure for the next generation of interconnected game and 3D ecosystems.

You're our in-house expert for the "other side". We're not porting a game—we're integrating engines themselves. Your deep expertise in another AAA engine will help us reconcile diverging lifecycles, serialization models, networking metaphors, and resource management so both can stay in sync. This role blends hands-on engine coding, plugin/middleware development, and cross-company collaboration. If wiring two full game engines into one coherent system sounds compelling, this is your chance.

What you'll be doing

  • Serve as subject matter expert on Unreal architecture and best practices, especially networking, serialization, resource management, and lifecycles.
  • Act as liaison between Unity and game engine partners, bridging technical concepts and architectural philosophies.
  • Design subsystems that map Unity features to Unreal equivalents (and vice versa) to synchronize content at scale.
  • Debug complex cross-engine interactions: crashes, race conditions, resource contention, and feature "impedance mismatches".

What we're looking for

  • Unreal Mastery: Extensive knowledge of Unreal source code, resource management, UObject lifecycle, and Slate UI
  • Integration Experience: You've written plugins or middleware that deeply modify or extend Unreal's core functionality
  • Networking Knowledge: Strong understanding of Unreal's replication model, authority handling, and synchronization toolbox
  • Unity Familiarity: Sufficient Unity experience to map concepts between engines, especially where abstractions clash.

You might also have

  • Background shipping games or middleware across multiple engines
  • Experience porting games between engines, including the asset conversions and build pipeline work.
  • Knowledge of FBX, USD, glTF, or similar interchange formats
  • Experience modifying game engine source code for custom builds or specialized features.

Additional information

  • Relocation support is not available for this position
  • Work visa/immigration sponsorship is not available for this position
