About The Role

Blacksmith Agency is building an AI automation layer into every part of how we work. As LLM Engineer at Blacksmith, you own and ship our internal automation roadmap.

You work directly with engineering and delivery leadership to take a documented roadmap of automation workflows and turn them into shipped, working systems. This role is for someone who has already built things with LLMs and can show it.
