Lead Structural Engineer - Marine Concrete Design

Sperra Seaworks Limited is advancing the next generation of marine and offshore infrastructure using 3D printed concrete and advanced structural design. Our mission is to develop practical, scalable solutions for offshore construction - including anchors, floating platforms, and subsea systems - supporting emerging forms of marine energy and resilient coastal development.

With headquarters in Los Angeles and growing operations in Europe, Sperra Seaworks Limited is expanding its engineering team in the UK to support projects across Europe and the Middle East

• A structural engineer with extensive reinforced concrete design experience, ideally in marine, port, or coastal environments
• Skilled at developing conceptual through detailed designs, with a strong sense of constructability and practical implementation
• Experienced applying Eurocode, BS EN, DNV, and related standards to non-standard and complex structures
• Comfortable generating design solutions for emerging construction methods, including 3D printed concrete
• Creative and resourceful—able to propose and evaluate structural concepts beyond conventional approaches
• Organised and effective at managing design workflows, documentation, and project deliverables
• A clear communicator who works well with contractors, fabricators, and multidisciplinary teams

As Lead Structural Engineer, you will shape the design and delivery of Sperra’s UK marine infrastructure projects. You will lead concrete structural design across concept development, detailed design, fabrication planning, and prototype development. While analysis remains part of the work, the emphasis is on design leadership, creativity, and project execution. Working closely with Sperra’s R&D and fabrication teams, you will help translate prototypes, material testing, and computational models into manufacturable offshore and coastal infrastructure solutions.

As Sperra Seaworks Limited’s first UK-based hire, you will help establish our engineering and operational presence in the region. You will shape local engineering practices, coordinate with UK and EU partners, and support the development of a highly capable UK engineering hub within Sperra’s global portfolio.
