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.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You Will Do
- Design and build full-stack features from spec to production, including AI agents capable of processing complex 400-page technical certification files.
- Collaborate directly with customers to understand their workflows and translate messy real-world certification processes into elegant software solutions.
- Take full ownership of product surface areas, moving fluidly between infrastructure, frontend, and the model layer to solve the most valuable problems.
The ideal candidate
- Demonstrable track record of building and maintaining complex systems that have been used by real people in a production environment.
- Exceptional engineering strength across various stacks like Rust, Python, Go, or TypeScript with a focus on speed, judgment, and high standards.
- Thrives in an ambitious, in-person startup culture in Shoreditch where you work without strict specs and possess the drive to "go to the source."
