Salary: 65-85K plus excellent benefits package. A relocation package and Visa/Sponsorship support is available for this role if required.
About The Opportunity
Our client is a fast-growing maritime technology business developing wind-assisted propulsion systems that help reduce fuel consumption and emissions across global shipping.
They are now looking to appoint a Principal Design Engineer to join their growing engineering team. This is a hands-on role 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 is an excellent opportunity to join a mission-driven business developing real climate-impact technology in a highly innovative environment and would suit someone genuinely motivated by sustainability and the opportunity to contribute to cleaner shipping.
Responsibilities
- Leading the mechanical design of subsystems in line with programme objectives
- Owning the development of wing geometry, balancing performance, structural integrity, and manufacturability
- Developing and managing load cases across classification and real-world operating conditions
- Translating load cases into clear design requirements
- Defining structural design philosophy and ensuring compliance with classification standards
- Performing and overseeing structural analysis and design verification
- Developing and improving in-house structural analysis tools and methods
- Leading technical engagement with classification societies
- Acting as the internal authority for stress and fatigue analysis
- Supporting and reviewing the work of more junior engineers where appropriate
- Promoting high standards of engineering integrity, safety, and sustainability
Why Join
This is 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
- High levels of ownership within a small engineering team
- Broad exposure from concept through to production
- The opportunity to grow and progress with the business as the technology scales
