Senior Calculator

Would you like to make an impact on some of the largest infrastructure projects in the Netherlands? As a Senior Cost Engineer at Van Oord, you ensure that complex projects are both technically sound and financially accurate.

The Position

At Van Oord, we work every day on projects that protect and connect the Netherlands. Think of dyke reinforcements, coastal protection, and new infrastructure connections that contribute to a safe and accessible country. Examples include projects such as the Afsluitdijk, ViA15, several KRW and PAGW projects, and dyke reinforcement projects such as Tiel–Waardenburg, IJsselmeerdijk, and Groene Rivier Well. Behind every successful project is a strong tender team where engineering, strategy, and financial expertise come together.

As a Senior Cost Engineer, you play a key role in this process by supporting complex infrastructure projects with solid technical foundations and realistic financial estimates. With your experience, you help us make smart decisions in design, execution, and risk management. In doing so, you directly contribute to projects that make a real difference for the Netherlands.

Your Impact

In this senior role, you are the technical and financial conscience of our more complex tenders within the Infra Land product line. You work closely with tender managers, project managers, and engineers to develop strong and competitive proposals.

You combine technical expertise with leadership: while actively contributing to cost estimates yourself, you also guide and support colleagues within the estimating team. You look beyond the numbers and focus on smart solutions and practical execution strategies.

Your responsibilities include:

• Preparing multidisciplinary and complex cost estimates for infrastructure and dyke reinforcement projects.
• 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.

About You

For this role, we are looking for an experienced professional with a strong technical background and sharp analytical skills. You are able to quickly understand complex projects and translate technical details into realistic cost estimates and strategic advice.

You bring:

• A bachelor’s or master’s degree in Civil Engineering.
• 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

• Travel allowance (€0.31 per km) and home office allowance (€2,45 per day).
• 32 leave days per year.
• Variable bonus.
• Pension scheme.
• Collective health insurance (optional).
• Flexible working from home policy, 2 days a week when working on a full-time basis.
• Extensive learning and personal development possibilities, including a wide range of online courses via Goodhabitz.
