About Antioch

Antioch is the simulation platform for physical AI. We enable 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.

Responsibilities

• Build and operate the cloud infrastructure that runs Antioch’s cloud‑based simulations, including orchestration, scheduling, GPU pools, storage, and observability.
• Develop the customer‑facing web app where teams author scenarios, manage runs, visualize and replay simulations, and review results.
• Create internal tooling for simulation engineers, 3D artists, and customers: SDKs, CLIs, dashboards, and deployment pipelines.
• Design the agentic harness that lets coding agents drive simulation work end‑to‑end: APIs, MCP servers, tool wrappers, evals, and feedback loops.
• Own performance, reliability, and cost: profile bottlenecks, reduce compute spend, and harden the system as customer load grows.
• Partner directly with customers to integrate Antioch into their development workflows, including APIs, CI hooks, data exchange, and authentication.
• Communicate clearly with customers and internal teams about tradeoffs, constraints, and roadmap.
• Collaborate with Antioch’s founders, simulation engineers, and 3D technical artists.

Requirements

• 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 or C++ is a plus.
• Comfort across the stack: backend services and APIs, plus modern web front‑ends.
• Experience designing and shipping developer‑facing products such as SDKs, APIs, CLIs, or internal tools.
• Strong instincts for performance, reliability, and observability: profiling, debugging distributed systems, and designing for failure.
• Proficient use of coding agents (Claude, Codex, Cursor, etc.) as a force multiplier on top of solid engineering fundamentals.
• Interest in building agentic workflows: shipping components that LLMs and agents call into, with evals and guardrails for reliability.
• Track record of shipping production‑ready systems, not just prototypes.

Nice-to-haves

• Experience operating GPU‑heavy workloads (rendering, simulation, ML training).
• Experience building MCP servers, agent tool interfaces, or LLM evaluation harnesses.
• Experience with 3D, graphics, or rendering pipelines.

Preferred Qualities

• Located in NYC or open to relocating.
• High‑agency builder who takes initiative without waiting for direction.
• Deep care for the quality of shipped work and a strong sense of accountability.
• Enjoys the 0 → 1 environment and deliberately chooses it.
• Balances craft and pragmatism: pushes for excellence while delivering what’s needed now.
• Comfortable with uncertainty and enjoys diving across the stack to solve problems.
• Customer‑obsessed and motivated to make the product work for real people.

Why Antioch

Our customers build physical autonomous systems that must behave correctly in the real world, and our work directly influences whether they succeed. As a high‑ownership engineer you will own systems end‑to‑end, iterate quickly, and receive direct customer feedback. You’ll work with a founding team that has built and sold companies and contributed to leading organizations such as Google DeepMind, Tesla Autopilot, and Meta Reality Labs. Early team members help define engineering culture, product direction, and the company’s path to success.
