About Us
Greenjets is an innovative engineering company developing high-performance propulsion systems for the aviation market. Our work spans research and development, engine production, aircraft systems, technical integration and flight testing. We are committed to delivering high-grade engineering and best-in-class propulsion for unmanned aircraft.
We do things differently. We move fast, we experiment and we adopt technologies that push beyond the current state of the art. Our aim is to go further, faster and more efficiently, while keeping costs competitive.
All our propulsion systems are designed, developed and manufactured in the UK. We focus on high-quality, reliable and cost-effective products supported by a robust, secure and ethical supply chain.
About the Job
We are looking for a hands-on Propulsion Development Technician to help build and develop a novel, high-performance propulsion system.
You will work closely with our engineers throughout the complete development cycle: assembling prototype systems, preparing and carrying out tests, inspecting components, identifying faults, tearing systems down and rebuilding them ready for further development.
This is a practical and varied role where precision, curiosity and sound mechanical judgement matter. You will be working with finely engineered components and extremely tight tolerances, so attention to detail and a methodical approach are essential.
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.
You do not need previous aviation experience. We are particularly interested in people whose skills come from other demanding engineering environments, such as race engines, aerospace or precision gearbox development.
What You'll Do
- Assemble and rebuild prototype propulsion systems and subassemblies.
- Inspect precision components before and after testing, identifying wear, damage and manufacturing issues.
- Prepare systems, test equipment and instrumentation for development testing.
- Support the safe operation of test equipment and development rigs.
- Tear down tested systems and record their condition accurately.
- Diagnose mechanical faults and help determine their root causes.
- Work closely with engineers to turn test findings into practical design and process improvements.
- Measure components accurately using appropriate inspection and metrology equipment.
- Maintain clear build, inspection and test records.
- Develop and improve assembly, inspection and maintenance procedures.
- Ensure components, tools and work areas are kept clean, organised and controlled.
- Follow all relevant quality, safety and engineering processes.
- Contribute ideas and practical insight in a fast-moving development environment.
Desirable Qualifications, Experience & Attributes
We are interested in practical ability and relevant experience, not just formal qualifications. You may have developed your skills through an apprenticeship, technical training, motorsport, specialist engineering or another hands-on route.
Get help with your application
Your very own career expert that helps elevate your application to the next level.
You will ideally bring:
- Experience assembling, inspecting and rebuilding high-precision mechanical systems.
- Experience working with very fine tolerances, close fits and finely finished components.
- A background involving gearboxes, race engines, aerospace engines or comparable precision machinery.
- Strong mechanical fault-finding and problem-solving skills.
- Confidence using precision measuring equipment and interpreting engineering drawings.
- A careful, clean and methodical approach to assembly work.
- The ability to recognise small changes in component condition, fit or system behaviour.
- Good written and verbal communication, including accurate technical record-keeping.
- A collaborative mindset and willingness to share observations and ideas.
- The flexibility to work with evolving designs, processes and test requirements.
- A strong commitment to safety, quality and doing the job properly.
Experience with development testing, prototype builds, rotating machinery, high-temperature systems, test instrumentation or formal inspection processes would be useful, but it is not essential.
Above all, we are looking for someone who enjoys understanding how complex mechanical systems work and who takes pride in assembling, testing and improving them.
