Build and own a simulation-ready character pipeline for robotics and autonomy. Develop Python tools connecting Unreal Engine, MetaHumans, USD, and Isaac Sim; create character controllers, motion-matching and procedural animation systems; integrate prompt-based animation models; refine animation, rigs, clothing, hair, accessories, and prop physics; and support synthetic data generation and customer engagements.
Location: New York City (in person), San Francisco (in person), or New Zealand (remote) | Type: Full time, onsite | Team: Technical Art
Who are we?
Antioch is the agentic simulation platform for robotics and autonomy. Teams design, train, and test physical systems in high-fidelity cloud simulation, accelerated by 3D-native agents. We build precision-calibrated digital twins and run massively parallel simulation scenarios, so customers spend less time on expensive, slow real-world testing. Our customers include leading robotics, autonomy, and perception teams working in manufacturing, logistics, construction, and safety.
Who are we looking for?
Character TDs who will develop our sim-ready character pipeline (USD, Omniverse, Isaac Sim, MetaHumans) and push the realism of our simulations. You'll work across character creation with a focus on MetaHumans, character controllers, hand-tuned and procedural animation, and prop physics. This is an early, high-ownership builder role, and you'll help shape our entire character pipeline.
What you'll do
- Build Python pipeline tools to create and export MetaHumans from Unreal Engine to Isaac Sim, conforming to USD standards.
- Design and implement character controllers with motion matching and procedural animation, focused on humanoids and expanding to quadrupeds.
- Integrate frontier models for prompt-based animation to support massively parallel synthetic data generation.
- Create and refine animation clips from third-party libraries, procedural generation, and video-to-motion workflows.
- Rig and refine clothing, accessories, and props, with dynamic physics where needed.
- Build modular character configuration and waypoint animation into the simulation platform.
- Represent Antioch in customer conversations and site visits.
What we're looking for
- Expert knowledge of Unreal Engine, motion matching, and animation Blueprints, with the ability to translate that to a new engine.
- A strong portfolio of Python tooling for character creation and animation in real-time engines, preferably with Unreal MetaHumans.
- Experience with procedural character animation, prop interaction, and generative pipelines.
- Deep knowledge of rigging and performant physics for clothing, hair, and accessories.
- Strong character animation experience, especially with Sequencer and Control Rig in Unreal Engine.
- Comfort with agentic-assisted development workflows.
- A track record of shipping production-ready capabilities.
- Nice to have: NVIDIA Omniverse or Isaac Sim, USD pipelines, Newton or Warp, synthetic data or robotics work, sensor-ready materials.
