About the Opportunity
Our client is a pioneering maritime technology business on a mission to decarbonize global shipping. They are developing revolutionary wind-assisted propulsion systems that significantly reduce fuel consumption and environmental impact.
As the Principal Design Engineer, you will serve as a technical authority within a fast-growing engineering team. This is a hands-on, high-responsibility role where you will bridge the gap between ambitious concept development and rigorous maritime compliance. If you are a marine structural expert motivated by sustainability and the challenge of bringing "Big Steel" innovation to the open seas, this is your next career move.
The Role & Responsibilities
In this senior leadership position, you will own the structural development of key product subsystems, ensuring they are robust, compliant, and ready for real-world deployment.
Structural Authority: Define the structural design philosophy and act as the internal expert for stress, fatigue, and buckling analysis.
Compliance Lead: Take the lead on technical engagement with major classification societies (DNV, LR, etc.) to ensure designs meet stringent maritime standards.
Design Ownership: Lead the mechanical design of subsystems, specifically balancing wing geometry with performance and structural integrity.
Load Case Management: Develop and manage complex load cases across real-world operating conditions and translate them into clear design requirements.
Methodology: Develop and improve in-house structural analysis tools and verification methods.
Mentorship: Support and review the work of junior engineers, championing high standards of engineering integrity and safety.
Key Requirements
Education: Degree in Naval Architecture, Mechanical, Structural, or Marine Engineering.
Experience: 5-10 years of experience in designing marine structures specifically approved by classification societies.
Sector Expertise: A deep-rooted background in the Marine industry is essential.
Regulatory Knowledge: Proven experience working directly with bodies such as DNV, LR (Lloyd’s Register), or NK to achieve technical approval.
Technical Proficiency: High proficiency in Siemens NX, Autodesk Inventor, or equivalent 3D CAD tools.
Analysis Skills: Strong expertise in FEA, hand calculations, and translating load cases into validated structures.
Mindset: Comfortable navigating the fast-paced, evolving environment of a high-growth technology startup.
Why Join?
You will be a key player in a mission-driven business delivering tangible climate-impact hardware.
High Levels of Ownership: Influence the design philosophy of a product scaling for global use.
Impact: Work on hardware that directly contributes to a cleaner, more sustainable shipping industry.
Stability & Support: Comprehensive relocation and visa sponsorship for candidates looking to move to the UK’s premier maritime hub.
