AI training data startup building infrastructure for spatial intelligence and synthetic worlds

Software Engineer, SDK & Engine Integrations

Los AngelesOn-site$80K - $180K4 - 10 years
You'll own the bridge between our multimodal data pipeline and the engines that consume it—shipping C++ plugins for Unreal and Unity that let robotics and simulation teams ingest licensed visual data without friction. Most days split between profiling SDK memory footprints, debugging Blueprint interop, and negotiating Python-to-native bindings that don't crater frame budgets. The integration layer you build becomes invisible infrastructure for teams training perception models on synthetic environments.

What they're looking for

  • 4+ years shipping C or C++ in production, with measurable ownership of SDKs, plugins, or engine-adjacent tooling
  • Deep familiarity with Unreal Engine or Unity internals—knows the difference between a UObject lifecycle bug and a rendering thread stall
  • Comfortable writing Python glue that bridges native boundaries without becoming a performance liability
  • Has survived at least one greenfield CI/CD setup for cross-platform C++ builds; knows why caching matters when iteration time kills velocity
  • Experience with synthetic data generation, computer vision pipelines, or simulation environments preferred
