Principal Design Engineer

Work 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
