## Job 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.

### WHAT WE'RE LOOKING FOR

- Typically 3 to 10+ years of experience building and operating production backend systems.

- Strong distributed systems experience, including designing for reliability and operating systems through failure.

- Hands-on expertise with containers, Linux internals, sandboxing, and safely running untrusted code.

- Experience building Python services and working with infrastructure tooling such as Modal.

- Practical experience with OAuth, webhooks, rate limits, and third-party API integrations.

- Background in infrastructure, platform, developer tools, runtime systems, or secure code execution, with experience designing multi-tenant systems.

### COMPENSATION & BENEFITS

Visa sponsorship is not available.

### LOCATION

On-site in Munich, Germany. Candidates based in Warsaw, Poland, or willing to relocate to Munich or Warsaw for on-site work may also be considered.

**Live in Clera’s hiring system.** Read from the company's own applicant tracking system, not reposted from a job board — so it's a real, open requisition rather than an ad that outlived the role.

We remove it as soon as it disappears at source.
