Job description

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:

As an Aircraft Design Engineer at Greenjets, you will focus on early-stage aircraft concept design, defining the overall configuration, aerodynamic performance and layout of future aircraft.

This role sits at the start of the development flow. You’ll generate airframe concepts, evaluate trade-offs and use CFD and analysis tools to guide design decisions before handing concepts over to the detailed design team.

You’ll work closely with propulsion engineers to ensure tight integration between airframe and engine performance.

What You'll Do:

• Develop aircraft concepts from initial requirements and mission profiles


• Define airframe layouts, configurations and aerodynamic surfaces


• Perform aerodynamic analysis using CFD and analytical methods


• Assess performance trade‑offs including weight, drag, stability and efficiency


• Support early structural and systems integration considerations


• Collaborate with mechanical design and development teams to ensure concepts are feasible


• Refine designs based on test data and iteration feedback

Desirable Qualifications, Experience & Attributes:

• Degree in Aerospace Engineering or related discipline


• Strong understanding of aerodynamics and aircraft performance


• Experience with CFD tools and aerodynamic analysis methods


• Ability to work at the concept and systems level


• Comfortable making engineering trade-offs with incomplete data


• Interest in experimental, unmanned or non-traditional aircraft


• Clear communicator able to translate concepts into actionable designs
