Senior Marine Geotechnical Engineer

Help shape the future of energy.

This role forms part of the Strategic Infrastructure Offshore Engineering Team, responsible for supporting the delivery of national infrastructure that is integral to Net Zero.

As a Senior Marine Geotechnical Engineer, you'll give technical input and provide quality management across the portfolio of work. You will support the design, engineering, and delivery of subsea cables, extending to the land interface to the transition joint bay (TJB) and onshore HVDC cable route sections.

As part of the role, you'll manage suppliers to ensure survey data is collected, processed, and supplied to the correct standards and specification. You'll be familiar with industry practices and standards covering the acquisition, processing, and interpretation of geotechnical survey data, working closely with internal and external stakeholders, including survey contractors, consultants, Project Managers, and joint-venture partners.

You will also lead on the implementation and management of workflow and standards within the marine and onshore Geospatial environment. The principal value created by this role is the supervision and management of quality to ensure National Grid and our partners can be highly confident that the products and services provided will result in agreed outcomes.
