Making a difference in the world by applying your knowledge and skills. That is what you do at Haskoning. As a Medior Mechanical Engineer, you apply your acquired knowledge in projects that have a positive impact on our society, while getting plenty of room to develop yourself.

What will you do as a Medior Mechanical Engineer

As a Medior Specialist Mechanical Engineering, you will work on interesting challenges in the field of mechanical engineering. You will give advice, make and test designs of building-related installations, and ensure an integrated installation design that fully matches the ambitions of the client.

Working together with colleagues in multidisciplinary teams, you will contribute your expertise to integrated projects that almost always require customized solutions. You look beyond the known and proven solutions, and in your projects, you may also manage one or more junior installation technicians.

Some examples of what you can do in a project:

  • Identifying the scope and purpose of a design.
  • Modeling single-sided diagrams of the mechanical installation and coordinating them with other disciplines for initial space reservations.
  • Providing project documentation to ensure the quality of information flow required by contractors and regulatory authorities.
  • Writing technical specifications and reports.
  • Reviewing contractor prequalifications and creating summary evaluations for tender assessments.
  • Assisting the Project Manager with preparing and assessing project costs and risk assessment.
  • Providing input for large integrated tenders and writing quotations.

Beyond project-related activities, you will also contribute to optimizing our business processes and to safeguarding and sharing knowledge about your own field, both within your team and within our MEP Community.

Where you will work

At Haskoning, you will join an independent, employee-owned international consultancy that combines engineering, design, and consultancy services with software and technology. Our mission, "Enhancing Society Together," drives us to create a positive impact on the world.

We offer purpose-driven and challenging work in diverse international projects, leveraging our 140+ years of expertise. With over 6,800 employees in more than 25 countries, we work together to turn challenges into opportunities and make a real impact on society. We collaborate with leading clients in markets such as infrastructure, climate resilience, renewable energy, decarbonisation of industry, and sustainable mobility.

As a Medior Mechanical Engineer, you will become part of our Business Line Industry & Buildings. We are committed to working on projects that have a positive impact on our society—a society full of buildings and industry that are well integrated in their environment and in which people feel comfortable, as well as a society with industry that cares about sustainability and with forms of energy generation that are as sustainable as possible.

Together with thousands of colleagues worldwide, we support our clients with their challenges from the very first moment. By combining the skills and knowledge of our colleagues with the latest digital applications, we come up with smart and innovative solutions that really help our clients. Our clients are in a wide range of markets such as fast-moving consumer goods, data centres, renewable energy, chemicals, real estate, government, education, and healthcare, ensuring no lack of variety—both inside and outside the Netherlands. We match your interests and our needs to decide which projects you will work on.

What you bring

You are a committed Engineer with an entrepreneurial slant, able to identify market developments, see opportunities, and have an eye for the customer. As a team player, you prefer to work in a multidisciplinary team. You have professional knowledge in the field of installations in buildings and are eager to contribute to the further expansion of installation knowledge within Haskoning. You ensure that the contractor can build exactly according to our model without revisions.

In addition, you have:

  • A completed academic or applied sciences degree in mechanical engineering, building services, energy technology, or HIT-W.
  • Minimum 10 years of relevant work experience.
  • Knowledge and experience with integrated projects (Revit & BIM).
  • Good communication and language skills in both Dutch and English.

Because we always want to improve our way of working, it is a plus if you are interested in digitization, innovative ideas, and are not afraid to use a new (software) program or new working method in your project.

What we offer you

  • A solid foundation: A competitive base salary with annual increases.

  • An attractive compensation package: Including a strong pension scheme with an 18.3% employer contribution, a 2.15% personal budget, and annual profit sharing. You’ll also have the opportunity to purchase company shares and share in our success.

  • Work-life balance: 28 vacation days (based on full-time employment), with the option to purchase an additional 16.5 days per year and to exchange three public holidays for days that are personally meaningful to you. We work in a hybrid model with flexible hours, a home office allowance, and a fully equipped home workspace.

  • Development opportunities: A wide range of training and development programs, including tailored learning paths, learning weeks, and various knowledge-sharing groups.

  • Travel allowance: A conveniently located workplace at one of our offices, with travel expense reimbursement and an NS Business Card. If you walk or bike to work, you’ll receive a higher travel allowance—encouraging sustainable commuting.

  • Informal and inclusive culture: A welcoming and open environment with voluntary social and sports activities, and employee networks such as Pride and Young Haskoning.
