Descrição

• Build the agent runtime: context, tool choice, approval waits, and knowing when to act, ask, or stay quiet • Write and keep tuning the system prompts; ensure proactive behavior without spamming the team channel • Own the eval and regression harness; test prompt changes like code • Make long-running work survive interruptions, retries, and flaky APIs • Implement guardrails, including approval gates for risky actions and strict customer data separation • Work directly with the founder and early users, turning feedback into shipped behavior

🎯 Requisitos

• You've shipped tool-using LLM agents to real users in production. Demos and prompt wrappers don't count • Good instincts for agent initiative, and the test results to back them up • Hands-on experience building eval and regression suites for LLM behavior • You understand safe tool execution, prompt injection, and multi-tenant data risk • Solid backend skills in Python or TypeScript (async jobs, retries, state) • You take a fuzzy problem from prototype to production and can explain the tradeoffs along the way • Excellent written and verbal communication; you can explain a tradeoff to a founder or a user without a whiteboard • Nice to have: MCP, or integrations with tools like Slack, Gmail, Notion, or Linear • Nice to have: Eval and tracing tools such as Braintrust, Langfuse, or LangSmith • Nice to have: You've been an early engineer at a startup before and still liked it

🏖️ Benefícios

• Founding equity • A direct line to the founder and early users, with no layers in between • Remote from Latin America or Eastern Europe, with solid overlap with US Pacific time • The tools and models you need to do the job properly • A small, experienced team that trusts you to run your own work
