## Description

### About the Role

Build and operate the backend systems that let AI agents use connected tools reliably. You will own core infrastructure across integrations, secure code execution, and multi-tenant data, working closely with the founding team in a fast-moving environment.

### What You'll Do

- Design and operate a tool gateway that exposes connected APIs and MCP integrations through a Python SDK, with routing, authentication, rate limits, and reliability built in.

- Run persistent, isolated Linux sandboxes for workspaces, with attention to security, autoscaling, and cost.

- Own durable, high-performance multi-tenant state and persistence systems designed to handle failures.

- Identify and resolve integration issues, then improve system architecture to prevent them from recurring.

- Work directly with users and the founding team to make and ship product and infrastructure decisions.
