Job Description

Job Description – Structural & Composite Engineer (Offshore Structures) Tree Composites is seeking a Structural & Composite Engineer to work at the interface of offshore steel structures and composite materials. The role covers structural analysis and FEA, the design of steel and steel-to-composite connections, post-processing of experimental results, and certification support, in close collaboration with our design, manufacturing and research engineers. If you have a solid background in structural engineering, a passion for composite materials, and want to help bring new technology to the offshore wind market, this role could be your next career step. About Tree Composites Tree Composites develops composite joints for large steel structures, with a focus on offshore wind foundations. By replacing complex welded connections, our technology can reduce steel use and simplify manufacturing while improving fatigue performance. We design and manufacture composite joints for offshore wind foundations that enable faster manufacturing and lower steel use. We are a start-up, founded in 2020 to bring our disruptive technology from TU Delft research to the market. Your Responsibilities Perform structural analysis and design of offshore steel structures and connections, including FEA at global structure and detail level Design and assess composite and steel-to-composite connections under static and dynamic loading Carry out R&D tasks related to composite materials: testing, calculations, report drafting and post-processing of experimental results Draft certification documentation for our products, addressing both steel and composite aspects and ensuring they meet industry and regulatory standards Collaborate closely with design, manufacturing and research engineers to optimise material behaviour and structural integrity Communicate technical results and contribute to project coordination Contribute to continuous improvement of our engineering methodologies Your Background Master's degree in Civil, Structural, Mechanical or Aerospace Engineering or a related field, preferably with a focus on composites or structural mechanics 2–6 years of experience in structural engineering, with FEA at both global structure and structural detail level Experience with composite materials and/or steel structures; affinity with both is a strong plus Proficiency in software tools such as SACS, Abaqus, CATIA, Siemens NX or similar, as well as Python for scripting tasks Excellent verbal and written communication skills, with high proficiency in English; Dutch is a plus but not required Detail-oriented, while able to manage your time effectively to meet deadlines A valid European Union work permit is required for this role What We Offer A full-time job, on site at our location in Delft, reporting directly to the lead engineer A meaningful, impactful role in a sustainable company working to accelerate the energy transition Collaboration with top-tier research institutions such as TU Delft A fun place to work in an informal, young team that enjoys what they're doing The opportunity to grow within a growing company, with ample scope to specialise and shape your role A market-competitive salary, 28 holiday days and pension contributions How to Apply Please send your CV and cover letter to [email protected].
