About Sperra Seaworks LimitedSperra 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

Who You AreA structural engineer with extensive reinforced concrete design experience, ideally in marine, port, or coastal environmentsSkilled at developing conceptual through detailed designs, with a strong sense of constructability and practical implementationExperienced applying Eurocode, BS EN, DNV, and related standards to non-standard and complex structuresComfortable generating design solutions for emerging construction methods, including 3D printed concreteCreative and resourceful—able to propose and evaluate structural concepts beyond conventional approachesOrganised and effective at managing design workflows, documentation, and project deliverablesA clear communicator who works well with contractors, fabricators, and multidisciplinary teamsWhat You Will DoAs 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.

Primary ResponsibilitiesLead structural design for concrete marine and offshore structures, including novel 3D printed systemsDevelop conceptual designs, detailed drawings, and specifications for prototypes and project deliverablesBalance structural performance, code compliance, durability, and manufacturability in marine environmentsEvaluate constructability constraints and coordinate design details with fabricators and contractorsSupport project management activities, including scope definition, scheduling, technical documentation, and client coordinationPrepare design reports, calculations, and documentation compliant with Eurocode, BS EN, and DNV standardsContribute to early-stage concept development and applied R&D effortsSupport prototype development and testing, interpreting structural behaviour to refine design assumptionsCommunicate design intent clearly to internal teams, external partners, and clientsPerform and review finite element analysis using SAP2000 and ABAQUS

QualificationsBachelor’s degree in Civil or Structural EngineeringMaster’s or PhD with focus on concrete, marine, or offshore structures (preferred)Chartered Engineer (CEng) or working toward chartership (strongly preferred)7+ years of structural engineering experience, including reinforced concrete and marine/coastal structuresStrong command of Eurocode, BS EN, DNV, and/or API standardsExperience delivering projects from concept through detailed design and deploymentStrong communication skills in a remote, multidisciplinary environmentExperience with marine energy, offshore structures, or naval architecture is a plusProficiency in structural analysis and FEM tools (e.g., SAP2000, ABAQUS)

What You Will GetCompetitive compensation package commensurate with experienceEmployer-contributed pension scheme25 days annual leave + UK bank holidaysHome-office equipment and engineering software/tools providedFlexible remote work with periodic travel to project and fabrication sitesOpportunity to shape Sperra’s UK engineering presence and influence technical strategyWork on cutting-edge projects at the intersection of marine infrastructure and advanced manufacturing
