We are looking for a talented Senior AI Engineer to join a brand new delivery squad focused on solving new client problems in 4-week cycles. Each project is designed to produce a working pilot that demonstrates clear value, not a polished long-term system. You’ll work in a 4-person team (AI Engineer, Product Manager, Data Scientist, Principal for AI Engineering), using AI coding tools (e.g. Claude Code) to reduce build time and get solutions into a usable state quickly. The role includes direct interaction with clients, where you’ll help shape solutions and explain technical decisions.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
