About The Role

Blacksmith Agency is building AI into every part of how we work. As Senior AI Engineer, you will own and ship our internal automation roadmap, focusing on production LLM and agent systems that our team uses daily. This is a builder role, not research, and you will not train models.

What You Will Build

• Agents and workflows with tool use and function calling on Anthropic and OpenAI, using a framework or plain APIs.
• Evals to demonstrate improvements and guardrails to prevent unsafe actions.
• Integrations with WordPress, Figma, Google Workspace, Slack, and our internal systems.
• Internal tools that significantly reduce time on delivery, sales operations, and project management.

What You Bring

• 2+ years of experience building production software in Python or TypeScript / Node.js.
• At least one LLM or agent system you have built that ran in production with real users.
• Experience in tool use, evals, and handling failures.
• Knowledge of REST APIs, webhooks, and cloud deployment.
• Strong spoken English to discuss technical decisions with the US team.

Not a fit if

• You freelance or contract for other clients alongside this job.
• Your LLM work consists of demos, tutorials, or chat prompting, or you are focused on model training and research.
