AI Deep Engineer (Agent Runtime)

CodeSpar builds financial infrastructure for agents that pay and get paid. A person or company defines a mandate, and our systems check the limits before a payment is sent.

We’re hiring an engineer to build the runtime agents use to call that infrastructure.

The work includes tool calls, MCP servers and payment-provider integrations. You’ll also handle credentials so they stay out of the agent’s context.

You should have shipped agents to production and be comfortable with TypeScript or Python.

Remote, full-time, Brazil.

Apply through LinkedIn, or email fabiano@codespar.dev with “Agent Runtime” in the subject. Include a short introduction and a link to something you’ve built.
