Senior Structural Engineer (”Constructeur Immersive Tunneling & Marine Works; ENG

Position: Senior Structural Engineer (”Constructeur”) - Immersive Tunneling & Marine Works (ENG)
We are looking for a  Senior Structural Engineer  who will contribute to the design and delivery of complex civil and marine infrastructure projects across international locations.

Our client is a highly specialised engineering partner operating in the field of complex civil infrastructure, with a strong focus on immersed structures, marine operations, and precision monitoring. With more than 25 years of experience, the organisation supports leading international contractors and project owners across Europe, Asia, and the Americas in delivering technically demanding projects.

Positioned at the intersection of design, engineering, and execution, our client plays a key role in projects involving immersed tunnels, caissons, and large‑scale marine structures. Their work ensures that complex installations are engineered, transported, and positioned with a high degree of accuracy in challenging environments where execution risk and coordination are critical.

In this multidisciplinary role, you work closely with engineering, project, and site teams to develop and implement structural designs for challenging infrastructure environments.

Your Contribution

Advanced Structural Design:  Lead the development and review of structural designs for maritime and heavy civil projects, focusing on both permanent works and complex temporary installation phases.

Specialized Engineering:  Ownership of structural calculations related to the transport, buoyant stability, and subsea positioning of large‑scale elements (e.g., tunnel segments and caissons).

Tender Leadership:  Provide critical technical input for international tenders, developing innovative design solutions that mitigate execution risk.

Lifecycle Involvement:  Actively support the transition from design to site, ensuring that structural integrity is maintained during challenging transport and immersion operations.

Interface Management:  Coordinate with multidisciplinary teams to ensure structural designs are compatible with mechanical systems and precision monitoring equipment.

Risk Mitigation:  Identify potential structural failure modes in marine environments and propose robust, efficient engineering solutions.

Your Profile

Education:

Bachelor’s or Master’s degree in  Civil Engineering  with a specialized focus on  Structural Engineering .

Experience:

Minimum  5–8 years  in a structural design role, ideally within heavy civil, marine, or offshore industries.

Technical Expertise:  Proven experience in  Steel and Concrete design  for large‑scale infrastructure.

Mindset:  A "hands‑on" engineer who enjoys solving problems where the structure meets the water. You are comfortable moving between a CAD model and a construction site.

Communication:  Professional fluency in  English ; ability to collaborate effectively in multicultural project teams.

Mobility:  Willingness to travel to international project sites to provide technical oversight during critical execution phases.

What We Offer

Unique Project Portfolio:  Engage with non‑standard, high‑complexity engineering challenges that go beyond typical building or bridge design.

End‑to‑End Impact:  See your designs come to life as you follow projects from the first calculation to the final subsea positioning.

Global Career Path:  Work in an international environment that values technical mastery, precision, and collaborative problem‑solving.

Competitive Package:  A comprehensive salary and benefits structure aligned with the specialised nature of senior‑level marine engineering.
