Position Overview — Junior Structural Design Engineer (m/f/d), SeaRenergy Hamburg
This Junior Structural Design Engineer (m/f/d) — Primary Steel at SeaRenergy in Hamburg supports primary steel structural design activities across concept, pre-FEED, FEED, and detailed design stages for wind turbine foundations, OSS foundations, and OSS topsides — builds structural and FEM models and evaluates analysis results — contributes to ultimate, fatigue, and serviceability design checks — assists with reviews of external designs by checking calculations, drawings, and documentation under senior engineer guidance — checks designs against applicable rules, standards, guidelines, and project specifications — reviews load assumptions and structural details — and collaborates across engineering disciplines to understand fabrication, transportation, and installation requirements — in an international offshore wind engineering environment with hybrid working, comprehensive benefits, and genuine professional development support
Why This Role Matters: As Junior Structural Design Engineer at SeaRenergy in Hamburg, the structural models you build, the design checks you perform, and the external design reviews you contribute to are engineering work that directly affects the structural integrity, fatigue life, and constructability of offshore wind foundations and substations that will stand in the North Sea for twenty-five years, transferring loads from multi-megawatt wind turbines through steel jacket structures and monopiles into the seabed in one of the world’s most challenging marine structural environments. When your FEM model of a jacket node correctly captures the stress concentration at a tubular joint under the combined wave, wind, and turbine load case that governs the fatigue design, your review of a fabricator’s drawing package correctly identifies a weld detail that does not conform to the DNV fatigue class assumed in the design calculation — creating an RFI that gets the detail corrected before it is welded into a foundation that will be unmodifiable once installed offshore — or your understanding of the marine transportation load case correctly flags that the transportation acceleration loads for a specific OSS topside module exceed what the structural analysis assumed — you are not supporting structural engineering. You are contributing to the engineering decisions that determine whether offshore wind foundations perform safely and reliably across a quarter century of offshore operational life. That is the engineering consequence and professional significance of rigorous Junior Structural Design Engineering at SeaRenergy’s Hamburg offshore wind team.
Key Responsibilities — Your Role at SeaRenergy
Primary Steel Structural Design — Concept Through Detailed Design
- Support primary steel structural design activities across concept, pre-FEED, FEED, and detailed design stages — contributing to the progressive engineering development of wind turbine foundations, OSS foundations, and OSS topsides from the high-level structural concept that establishes the basic geometry and member arrangement through the increasingly detailed engineering that produces the fabrication-ready drawings and calculations that offshore wind foundation contractors build to
- Build structural and FEM models and evaluate analysis results — developing the finite element models of offshore primary steel structures that capture the structural behaviour under complex offshore load combinations, running analysis cases, interpreting results, and extracting the design-governing load effects and stress resultants that feed into the ultimate, fatigue, and serviceability design checks
- Contribute to ultimate, fatigue, and serviceability design checks — applying structural steel design to DNV GL, ISO, and project-specific design standards to verify that offshore primary steel members, connections, and joints meet the strength, fatigue life, and deformation requirements that the applicable design codes specify for marine structures in the target offshore environment
Design Review, Standards Compliance & Interdisciplinary Collaboration
- Assist with reviews of external designs by checking calculations, drawings, and design documentation under senior engineer guidance — developing the systematic design review competency that allows SeaRenergy to provide its clients with independent technical assurance that the offshore structural designs they receive from contractors and consultants meet the applicable standards, project specifications, and engineering quality expectations
- Check designs and deliverables against applicable rules, standards, guidelines, and project specifications — applying knowledge of DNV, ISO, EN, and project-specific technical requirements to the systematic verification of structural design outputs, documenting findings clearly for senior engineer review in a way that creates a traceable audit trail of the technical checking process
- Review load assumptions and structural details, and collaborate across engineering disciplines — engaging with marine engineers, geotechnical engineers, installation engineers, and fabrication specialists to understand how marine environmental loads, soil-structure interaction, transportation and installation load cases, and fabrication constraints influence the structural design, developing the multi-disciplinary engineering awareness that makes an offshore structural engineer genuinely effective in a project team
Qualifications & Profile — Does Your Profile Meet Most Requirements?
Essential Requirements
- Degree in civil engineering, structural engineering, naval architecture, ocean engineering, offshore engineering, or a related discipline — the academic foundation for offshore primary steel structural design and analysis work
- Initial relevant engineering experience — through coursework, a thesis, or an internship — with exposure to engineering standards or design guidelines demonstrating the foundational engineering competency and professional orientation that SeaRenergy is building on
- Sound knowledge of mechanics, structural analysis, FEM, and material behaviour — with a genuine interest in offshore structures, steel design, and marine, operational, and installation loads
- Good written and spoken English — essential for an international offshore wind project environment; German language skills are an advantage
- A careful and curious approach to engineering — with a collaborative mindset and willingness to continuously learn and develop — “we value a willingness to learn just as much as professional expertise”
Preferred & Advantageous
- Initial experience with FEM or CAD software — DNV Sesam, SACS, ANSYS, or NASTRAN knowledge is an advantage for offshore structural analysis work
- Familiarity with Python or MATLAB — for parametric analysis, post-processing, and engineering automation in structural design workflows
