High-fidelity simulation for Physical AI, at cloud scale. Join teams using Antioch to ship autonomous systems with confidence, entirely in simulation. Backed by Greylock.
About the role
Build and operate the cloud infrastructure that runs Antioch’s cloud-based simulations: orchestration, scheduling, GPU pools, storage, and observability. Build the customer-facing web app where teams author scenarios, manage runs, visualize and replay simulations, and review results.
What they're looking for
- We're hiring Platform Engineers to build the cloud infrastructure, customer-facing application, internal development tools, and agentic harness that power Antioch
- If you like the 0 → 1 grind and want your work to directly determine whether autonomous systems succeed in the real world, you'll fit right in
- You don't need every box checked. We're looking for strength in most of these:
- Strong full-stack engineering background, with production experience designing and operating cloud systems (GCP/AWS/Azure, Kubernetes, container orchestration, data pipelines)
- Deep fluency in Python. Fluency in Rust/C++ is a plus
- Comfort across the stack: backend services and APIs, plus modern web frontends
More about this role
Antioch is the simulation platform for physical AI. We allow teams to develop, evaluate, and generate synthetic data for their physical systems in high-fidelity cloud simulation, accelerated by 3D-native agents.
With Antioch, teams create precision-calibrated digital twins, generate testing environments, and run massively parallel simulation scenarios. By moving development out of the field and into software, Antioch drastically reduces dependence on expensive, slow, and incomplete real-world testing.
We work with leading robotics, autonomy, and perception teams to make the deployment of physical autonomous systems safer, faster, and more cost-effective.
We're hiring Platform Engineers to build the cloud infrastructure, customer-facing application, internal development tools, and agentic harness that power Antioch.
This is an early, high-ownership builder role: you'll design and ship the systems that customers and internal teams depend on every day, from the orchestration layer running massively parallel sims to the web app where engineers author scenarios and review results. You'll work across backend, frontend, infrastructure, and developer tooling.
