Build real-time 3D runtime protocols and execution models that let interactive 3D content encode, compress, and replay across engines and AI systems. Evolve engine-stack subsystems from low-level C++ runtime code through C# editor/build/simulation/streaming/playback APIs. Create systems to capture, serialize, stream, and synchronize scene and rendering state under tight latency and determinism constraints, and design interfaces for AI to inspect and validate outcomes.

Location: Washington, Bellevue, United States, California
Workplace: Remote
Employment Type: Full time
Job Function: Software Engineering
Seniority: Mid level

Key Responsibilities

  • •Define runtime protocols, formats, and execution models for encoding, compressing, and replaying interactive 3D content between engines and AI models.
  • •Own and evolve critical engine-stack subsystems from low-level C++ runtime code to high-level C# APIs across editor, build, simulation, streaming, and playback.
  • •Build systems to capture, serialize, stream, and synchronize scene state, components, assets, user interactions, and rendering data under tight bandwidth/latency/determinism/memory constraints.
  • •Design interfaces and feedback loops that let AI systems inspect engine state, invoke engine capabilities, and validate outcomes.
