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
- Develop and deploy multi-agent AI systems using Python (FastAPI) and LLMs to automate property viewings, sales, and contractor management.
- Build seamless full-stack user experiences with TypeScript, React, and Next.js that integrate deeply with CRMs, WhatsApp, and email platforms.
- Take end-to-end responsibility for shipping features, from initial architecture to production, seeing your work impact real property agencies within days.
The ideal candidate
- A top-tier graduate from Oxford, Cambridge, or Imperial, either graduating in 2026 or possessing 1-2 years of professional software engineering experience.
- Strong proficiency in Python and a desire to work across the full stack, including modern frontend frameworks and cloud infrastructure on AWS/GCP.
- A fast-moving, founder-mode mindset eager to thrive in a high-intensity startup culture that prioritizes rapid shipping and collaborative in-person work.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
