• Extensive experience in preparing project calculations for civil engineering and/or infrastructure projects.
• Knowledge of geotechnics, equipment, and complex execution methods.
• Strategic insight and strong advisory skills.
• Coaching abilities and the capability to help colleagues further develop themselves.

We offer you a position in which you will have an important contribution to our mission 'building a better world for future generations'. In addition, we offer you:

• A salary that matches your responsibilities and experience;
• Travel allowance (€0.31 per km) and home office allowance (€2,45 per day);

• Leading and coordinating estimating teams during tenders.
• Conducting and reviewing extensive risk analyses.
• Advising on alternatives, execution strategies, and contractual choices.
• Coaching and mentoring fellow cost engineers.
• Visiting project locations to define project assumptions and frameworks.
• Safeguarding knowledge and lessons learned for future tenders.

Your working environment

You will join Tendering & Engineering (T&E): the technical and strategic heart of Van Oord. Here, knowledge and experience from different disciplines come together to develop innovative solutions for complex projects.

Within the Infra Land product line, you will work on infrastructure projects in the Netherlands and surrounding countries. You will become part of an integrated tender team and a professional network of more than 30 cost engineers within the Business Unit Dredging & Infra, including 6 within Infra Land. Together, you ensure that our tenders are technically strong, financially competitive, and executable.

You will work closely with tender management, IPM team members, and other technical specialists. In this environment, you will have plenty of room to take initiative, share knowledge, and contribute to the further development of our tendering processes.
