Job description

We're seeking a Senior Mechanical Engineer / Design Engineer to join GT Wings, one of the UK's most exciting clean-shipping technology companies. If your background involves large mechanical assemblies, heavy structural systems, or marine-scale engineering, this is a rare opportunity to apply your expertise to a world-first technology shaping the future of commercial vessel design.

GT Wings is at an exciting stage of growth. With its first full-scale AirWing installation complete and multiple commercial projects in development, the company is now scaling from prototype to production building the future of wind-assisted propulsion for cargo ships. Engineering-led and purpose-driven, GT Wings combines innovation with precision, creating powerful, class-compliant hardware that helps decarbonise global shipping.

Joining as a Senior Mechanical Engineer / Design Engineer, you'll take a leading role in the detailed design and integration of the AirWing system bringing together large mechanical and structural components into cohesive, manufacturable designs. You'll work from concept to production handover, ensuring every element is robust, safe and optimised for real-world marine conditions.

Key requirements: You should be a capable and motivated Mechanical Engineer / Deign Engineer with a CV that demonstrates

• Degree in Mechanical, Structural, Marine Engineering or similar
• 3+ years experience working on large-scale mechanical systems, heavy machinery, offshore, or marine structures
• Proven ability to take designs from concept to production and assembly
• Strong 3D modelling, detailed drawing and design calculation capabilities
• Confidence operating in fast-moving R&D and build environments
• Experience applying engineering judgement and problem-solving under pressure
• Desire to contribute to a mission-driven clean-tech environment

Any exposure to marine or offshore engineering, large-structure or mechanism design, FEA, Inventor or similar 3D CAD, exposure to class/certification requirements (DNV/LR), actuation or control systems insight, familiarity with structural testing and validation is advantageous.

In return, you'll join an ambitious start-up at a pivotal time, working on leading-edge maritime hardware with support from experienced technical leadership. Expect a competitive salary (£45k -£60k DOE), hybrid flexibility (Hampshire-based hub), private health care and the chance to grow your career as GT Wings scales into global deployment.
