Why this role is remarkable
- Build the world's first AI-native infrastructure for the home, modernizing a fragmented industry currently split across agents, banks, and service providers.
- Backed by £2M in pre-seed funding from elite investors who previously built global financial infrastructure handling billions in daily transaction value.
- High-agency environment where your code directly manages real-world assets, financial integrations, and regulatory compliance for thousands of concurrent users.
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
- Architect and maintain scalable microservices using NestJS and TypeScript to automate the end-to-end rental lifecycle and financial rails.
- Collaborate with AI engineers to integrate LLMs into production workflows, pushing the boundaries of how AI handles real-world property and money.
- Own the full engineering cycle by participating in DevOps, infrastructure management on GCP/GKE, and database optimization across MongoDB paradigms.
The ideal candidate
- Strong proficiency in backend development (TypeScript/Node.js preferred) with deep experience building microservices and RESTful API architectures.
- Proven ability to manage complex data structures and event-driven systems, ideally with familiarity in MongoDB, Kubernetes, and GitOps practices.
- A first-principles thinker with an obsession for code quality and the adaptability to thrive in a fast-paced, high-stakes operational environment.

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.
