Senior Platform Engineer — Cloud, DevTools & Sim Harness

Antioch; New York (NY); On-site; USD 170,000 - 260,000; Full time

Job summary

Antioch is the agentic simulation platform for robotics and autonomy. We allow teams to design, train, and test their physical systems in high-fidelity cloud simulation, accelerated by 3D-native agents.

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 across backend, frontend, infrastructure, and tooling.

Qualifications

• Strong full-stack background with production cloud systems experience.
• Deep Python expertise; Rust/C++ a plus.
• Experience designing and shipping developer-facing products (SDKs, APIs, CLIs).
• Focus on performance, reliability, and observability in distributed systems.
• Track record shipping production-ready systems.

Responsibilities

• 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.
• Build internal tooling that lets simulation engineers, 3D artists, and customers move quickly: SDKs, CLIs, dashboards, and deployment pipelines.
• Build the agentic harness that lets coding agents drive simulation work end to end: APIs, MCP servers, tool wrappers, evals, and the feedback loops agents need to iterate reliably.
• 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: APIs, CI hooks, data exchange, and authentication.
• Communicate clearly with customers and internal teams about tradeoffs, constraints, and roadmap.
