What You Will Do
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.
- Design and execute comprehensive battery test plans covering charge/discharge, thermal performance, and system behavior under various profiles.
- Develop reproducible time-series simulations for battery fleets and low-voltage distribution networks to evaluate grid capacity and flexibility services.
- Analyze complex datasets using Python or MATLAB to reproduce hardware anomalies and provide actionable engineering recommendations for firmware improvements.
The ideal candidate
- A student or recent graduate in Electrical Engineering, Power Systems, or Power Electronics with strong circuit and three-phase power fundamentals.
- Demonstrated experience in a lab environment with a disciplined approach to electrical safety, testing documentation, and data automation.
- Excellent problem-solver who can translate vague technical questions into structured models, evidence-backed conclusions, and clear communications for non-specialists.
