Geotechnical Engineer

Netherlands, Noord-Holland, AmsterdamEngineering

Job description

At GBM Works, we developed a disruptive and innovative method to silently install foundations. Now, we are developing the tool, our Vibrojet®, for the next generation XXL monopiles used for wind energy offshore. Our patented method will solve major challenges in the offshore wind industry that are associated with the current method ‘piling’ such as harmful noise to marine life, potential delays, fatigue damage in the pile and scaling issues. We collaborate with leading offshore contractors and windfarm developers. As we venture into unchartered waters, we are looking for inventors who like to challenge the status quo and can push boundaries in cooperation with the existing team.

In collaboration with GROW Offshore partners, a €6.5 mln subsidy has been granted to the SIMOX project, which started in April 2021. During this project, GBM Works will test the method on bearing capacity and noise levels over the next 3 years. The interest from the market has grown significantly, the reason why we anticipate that the geotechnical expertise of GBM Works will lead to commercial consultancy and engineering assignments sooner than expected.

GBM Works has also approval of €1.9mln subsidy for SIMPLE-IIB project, which is the third project of the Silent Installation of Monopiles (SIMPLE) line of projects that will allow GBM Works to further develop its jetting technique and therefore take it one step closer to the application in commercial projects.

Amongst others, SIMPLE IIB's scope includes laboratory tests, manufacturing of prototypes and drivability, axial bearing capacity and scour protection tests - some of them in collaboration with the SIMOX Project.

The Geotechnical engineer participates in the product development team, which is responsible for the development of all future GBM Works products and services. Currently the main responsibility of the team, is the development of the Vibrojet® prototypes to be used in onshore as well as offshore conditions, for the installation of piles with outer diameter ranging from 2.2m up to 9m. The theoretical soil model that will be used for the prototypes together with all the jetting parameters, that will accompany the prototypes, will be validated through laboratory tests performed under the supervision of GBM Works. Therefore, strengthening the team with a Geotechnical Engineer is a top priority.


We are currently looking for a Geotechnical Engineer to strengthen our Geotechnical Team.

Your role will include the following

  • Interpret soil data and evaluate soil design profiles both for pile design as well as for driveability analyses, mainly for offshore wind farm projects.
  • Evaluate foundation design aspects, and installation procedures.
  • Assess geotechnical installation risks for monopiles.
  • Contribute to the evaluation/planning and /or performance of laboratory tests.
  • Contribute to the validation of the theoretical soil fluidization models through testing.
  • Contribute to the evaluation of possible impact of the fluidization technique to the design aspects of monopiles
  • Perform driveability predictions for the installation of monopiles for offshore wind farms in various parts of the world.
  • Work together with the rest of the geotechnical engineers within GBM Works, ad well as external Geotechnical Experts, and liaise with Clients for geotechnical topics regarding installation techniques.
  • Provide support and actively participate in continuous improvement of procedures and equipment.

What do we offer?

  • An experience-based salary.
  • Stock options
  • Reimbursement of travel expenses.
  • 25 paid holiday days.
  • Location in ETCA, Amsterdam.
  • A personal development plan.
  • Full-time position available immediately

More importantly, we offer an inspiring environment with highly motivated people that are determined to achieve goals.

Job requirements

What is your must-have skill set?

  • A master's degree in Civil / Geotechnical engineering in combination with at least 3 years of relevant working experience.
  • Experience in the following:
    • Interpretation of geotechnical investigation data and use of appropriate geotechnical/ geological design parameters.
    • Geotechnical design and analysis for Offshore Wind Farm foundations, such as drivability study, hammer selection, pile driving test, design for driven pile from concept to detailed design.
    • Use of existing digital platforms for geotechnical design (GRLWEAP, Opile, Plaxis).
  • Detail-orientated with the ability to make correct judgments.
  • Good at report writing.
  • Very good written and verbal English.

Additional assets

  • Familiarity with Pile driving instrumentation and monitoring services for the offshore and onshore industry, including back analysis of pile capacities, as well as relevant Standards.
  • Experience in constitutive modelling of soil behaviour and numerical modelling of geotechnical problems, as well as interest in experimental methods.
  • Knowledge of the Python programming language.
