We are building AI-powered tools for understanding global energy markets by combining LLM agents, real-time market data, and forecasting models—creating an AI Analyst that can reason about complex energy systems.
Our frontend is where massive datasets, predictive models, and AI systems become actionable. We design fast, data-heavy interfaces enabling users to explore energy markets, interrogate datasets, and interact with forecasting models in real time.
We are AI-native, powered by a modern tech stack:
- TypeScript
- React
- Next.js
- A monorepo architecture supporting rapid feature development and AI-assisted workflows.
The Role
We are hiring a Frontend Engineer to lead architectural evolution of our UI, partner with a team to develop a frontend structure designed for rapid, AI-assisted development.
Ideal candidates love product-building and thrive in a mission-driven, fast-paced start-up environment.
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
