£70-75K+ (neg) plus excellent benefits package. More may be available for the right candidate.

Relocation package and Visa/Sponsorship support available if required.

Join a fast‑growing maritime technology business developing wind‑assisted propulsion systems that help reduce fuel consumption and emissions across global shipping.

This is a hands‑on opportunity for a Principal Design Engineer to join a growing engineering team, with broad involvement across the design lifecycle
, from concept development through to detailed design and production‑ready hardware
.

Working closely with the Head of Engineering
, you will take ownership of key subsystems
, helping to deliver designs that are robust
, manufacturable
, compliant
, and ready for real‑world use. This role would suit someone genuinely motivated by sustainability and the opportunity to contribute to cleaner shipping
.

• Degree qualified in Naval, Mechanical, Structural, or Marine Engineering
• Around 5-10 years’ experience designing marine structures approved by classification societies
• Strong 3D CAD skills, ideally Siemens NX
  , Autodesk Inventor
  , or similar
• Strong experience in structural analysis
  , including FEA and hand calculations
• Proven experience translating load cases into robust design requirements and validated structures
• Experience working directly with classification societies and supporting technical approval
• Experience with DNV, LR, NK or similar bodies
• Strong understanding of DFMA
  , structural integrity
  , and manufacturability
• Comfortable working in a fast‑paced, chaotic environment

• Lead the design and structural development of key product subsystems
• Lead the mechanical design of subsystems in line with programme objectives
• Own the development of wing geometry
  , balancing performance
  , structural integrity
  , and manufacturability
• Develop and manage load cases across classification and real‑world operating conditions
• Define structural design philosophy and ensure compliance with classification standards
• Perform and oversee structural analysis and design verification
• Develop and improve in‑house structural analysis tools and methods
• Lead technical engagement with classification societies
• Act as the internal authority for stress and fatigue analysis

A rare opportunity to join a business developing real‑world clean technology for the global shipping market.

You will benefit from working on real climate‑impact hardware, enjoying high levels of ownership within a small engineering team, gaining broad exposure from concept through to production, and having the opportunity to grow and progress as the technology scales.
