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
- Prototype, validate, and ship full-stack features using React, Node.js, and Python to enhance AI agent capabilities.
- Design and scale robust APIs and AWS cloud architecture capable of handling complex banking agent workloads and security requirements.
- Collaborate directly with partner banks to observe workflows, identify pain points, and rapidly translate those insights into product improvements.
The ideal candidate
- At least 4 years of professional experience with a deep understanding of the modern web stack, specifically React, Node.js, TypeScript, and Python.
- Proven ability to design, deploy, and defend complex cloud systems and applications within an AWS environment.
- A product-minded approach with strong intuition for user needs and experience experimenting with AI to solve novel engineering problems.

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.
