Description du poste

About The Role

Blacksmith Agency is building AI into every part of how we work. As Applied AI 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.
