Early-stage climate tech AI startup
Job Description
Join a founder-led team building an agentic AI platform for renewable energy investment.

This hands-on internship offers the chance to ship user-facing AI tools that accelerate critical global energy infrastructure projects.

Why this role is remarkable
- Work directly with founders on a prize-winning platform that solves multi-billion dollar inefficiencies in renewable energy investment.
- Join a well-funded startup led by domain experts with background experience in energy M&A and climate technology.
- Ship production-level AI features that real investors use, rather than working on internal tools or minor maintenance.
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
- Build and maintain frontend interfaces for a specialized diligence platform using modern web frameworks.
- Develop backend services for document processing and complex AI orchestration pipelines.
- Implement LLM-powered features including automated risk classification, document Q&A, and agent-driven analysis.
The ideal candidate
- Proven builder with a portfolio of web applications or AI projects evidenced via GitHub or personal work.
- Proficiency in at least one frontend framework and one backend programming language.
- Strong curiosity about LLMs and the ability to work in the UK without visa sponsorship.

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.
