Apply NowWork on real climate-impact engineering. Not theory.
We’re hiring a Principal Design Engineer to join a fast-growing maritime technology company developing wind-assisted propulsion systems that reduce fuel consumption and emissions across global shipping.
This is a hands-on leadership role where you’ll own key subsystems from concept through to production.
What you’ll be doing
*
Lead mechanical and structural design of critical subsystems
*
Own wing geometry development - balancing performance + manufacturability
*
Develop and manage load cases (real-world + classification)
*
Translate requirements into robust, production-ready designs
*
Perform and oversee FEA + structural analysis
*
Act as technical lead with classification societies (DNV, LR etc.)
*
Be the go-to expert for stress & fatigue analysis
*
Support and mentor junior engineers
What you’ll need
*
Degree in Naval / Mechanical / Structural / Marine Engineering
*
5-10 years designing marine structures (classification-approved)
*
Strong 3D CAD (NX, Inventor or similar)
*
Solid FEA + hand calculations experience
*
Experience with DNV, LR, NK or similar
*
Strong understanding of DFMA & structural integrity
Bonus points if you have
*
Fatigue, buckling, or large welded structures experience
*
Exposure to aero-structures or performance-led design
*
Structural testing & validation experience
Why this role stands out
*
Work on real clean-tech hardware
*
Join a scaling engineering business
*
Own designs from concept to production
*
Genuine career progression as the company grows
