About The Role

Blacksmith Agency is building AI into every part of how we work. As LLM Engineer at Blacksmith, you own and ship our internal automation roadmap: production LLM and agent systems that real people on our team use every day. This is a builder role, not research. You will not train models.

Blacksmith Agency

• Engineering
• Full time, your only job
• Remote (Latin America and South Africa)

What You Will Build

• Agents and workflows with tool use and function calling on Anthropic and OpenAI, with a framework or plain APIs.
• Evals that prove a change made things better, and guardrails that stop a model taking a wrong or unsafe action.
• Integrations connecting WordPress, Figma, Google Workspace, Slack and our internal systems, including MCP servers.
• Internal tools that take measurable hours off delivery, sales operations and project management.

What You Bring

• 2+ years building production software in Python or TypeScript / Node.js.
• At least one LLM or agent system you built yourself that ran in production with real users.
• Hands-on tool use, evals and failure handling: validating model output, retries, human approval.
• REST APIs, webhooks and cloud deployment.
• Strong spoken English. You will talk through technical decisions on live calls with a US team.

Not a fit if

• You freelance or contract for other clients and would keep them alongside this job.
• Your LLM work is demos, tutorials or chat prompting, or your focus is model training and research.
