London (Hoxton) with occasional UK and international travel
Foundational role for an entrepreneurial builder
The Opportunity
This is not a maintenance role.
This is not a “design it and hand it off” role.
This is a from-zero-to-ocean role.
You’ll be the person who turns bold ideas into working marine hardware - sketching, building, testing, breaking, fixing, and deploying real-world systems that operate in some of the harshest environments on Earth.
If you love rapid prototyping, field testing, and seeing your work floating offshore (or bolted to a buoy in rough seas), this role was written for you.
What You’ll Do
You’ll own early-stage hardware development end-to-end, including:
- Rapidly prototyping, assembling, and testing marine hardware - buoys, sensor housings, mooring systems, and edge compute units
- Integrating, calibrating, and validating sensors (salinity, temperature, pressure, optical; e.g., CTDs, YSI EXO-class systems) to ensure reliable, high-integrity data
- Designing and iterating waterproof enclosures, solar power systems, and sensor layouts built for extreme marine conditions
- Collaborating closely with software, robotics, and oceanography specialists to ensure designs survive real-world deployment
- Sourcing marine-grade components, managing small-batch fabrication, and coordinating 3D printing or machining
- Documenting designs, iterating fast, and supporting field trials in the UK and overseas
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.
Who You Are
You’re hands-on first, theoretical second.
Strong experience building and testing real hardware, not just CAD models
Deep understanding of embedded systems, sensors, and marine/weatherproofing best practices
A true maker: engineer, hacker, inventor, and field tester rolled into one
Comfortable working in workshops, labs, harbours, and offshore environments
