Job Description

A Mandarin speaking Senior Mechanical Engineer is needed to join GT Wings, an ambitious engineering led CleanTech and MarineTech company developing wind assisted propulsion systems that help commercial vessels cut fuel consumption and emissions. Mandarin fluency is essential for this role.

Based in the Southampton area, this is a hands on, high ownership position within a small, expert team turning innovative concepts into production ready hardware now being deployed at sea. Visa sponsorship is available and we welcome applications from candidates prepared to relocate to the UK.

GT Wings is at a pivotal stage. With one full scale AirWing already on the water and further systems in build, the focus is firmly on manufacturable, scalable delivery. The culture is engineering first, mission driven and practical. Ideas move quickly from CAD to fabrication, assembly and real world operation.

As a Mandarin speaking Senior Mechanical Engineer, you will take ownership of key AirWing subsystems from early concept through to detailed design and manufacturing release. This is not a narrow design office role. You will balance creativity with rigour, ensuring every component is robust, elegant and ready for production in demanding marine environments.

Working closely with the Head of Engineering, you will produce 3D models, detailed manufacturing drawings and supporting calculations, while applying strong Design for Manufacture and Assembly principles. A key part of the role will involve liaising with Mandarin speaking international suppliers and manufacturing partners, supporting production activities and capturing lessons learned to continuously improve cost, quality and manufacturability. You may also review and guide junior engineers where appropriate.

Key requirements: You should be a capable and commercially aware Mechanical Engineer, Senior Mechanical Engineer or Mechanical Design Engineer with a CV that demonstrates:

• Fluency in Mandarin and English, with the ability to operate confidently in technical and commercial discussions
• Degree qualification in Mechanical, Structural or Marine Engineering
• 5 to 10 years experience designing mechanical systems within a manufacturing environment
• A track record of taking products from concept through to production, ideally within marine or offshore sectors
• Experience with fabrication, welding or large structural assemblies
• Strong understanding of Design for Manufacture and Assembly principles
• Proven experience driving cost reduction against defined targets
• Comfort operating in dynamic environments with real accountability

Proficiency in Autodesk Inventor or similar 3D CAD, exposure to class or certification requirements such as DNV or LR, experience designing large structures and knowledge of structural testing and validation would all be advantageous.

In return, you will join a scaling clean technology business where your work directly contributes to lower carbon shipping. Expect a salary of £45,000 to £60,000 depending on experience, visa sponsorship support where required, relocation support for international candidates, and meaningful ownership of real hardware as GT Wings moves towards wider global deployment.
