Specialist Energie en Duurzaamheid Netcongestie

Your core mission is to make electric construction work despite the limits of the Dutch power grid. Concretely, you develop and direct energy supplies and site layouts tuned to electric equipment, and you advise project teams on grid congestion, temporary connections, charging strategies and energy management. You work both with and without a grid connection, which means designing battery, hybrid and off-grid setups that keep sites running. You also run pilots and test environments for new energy concepts, analyse consumption data and turn it into practical improvements, and coordinate with grid operators, suppliers, partners and project teams. Based in Haaften, you travel occasionally to sites. Longer term, the role likely contributes to standardising how Dura Vermeer powers its sites, so that solutions proven in one project become the default in the next. That means building internal knowledge, not only solving today's problem.

You gain deep practical expertise in grid congestion, temporary connections and site energy management, areas where demand for knowledge is growing fast in the Dutch construction sector. Working with batteries, hybrid and off-grid systems gives you hands-on experience with technologies that many companies are only starting to explore. Running pilots means you learn how to set up tests, measure results and decide what to scale, which is valuable project and innovation experience. Coordination with grid operators and suppliers builds a network and insight into how energy infrastructure decisions are actually made. Dura Vermeer has its own academy with training and development options, so formal courses in your field are likely available. You also develop the ability to explain complex energy questions in plain terms, a skill that transfers to almost any sustainability role.

The posting asks for at least three years of experience in energy, technical services or construction, plus knowledge of energy issues, grid congestion or electric construction sites. A technical background, whether in electrical engineering, energy management or a related field, fits the profile, though the emphasis is on applied knowledge rather than a specific degree. Soft skills matter as much as technical ones. You need to switch easily between planning and practice, be curious and down to earth, and genuinely enjoy collaboration. The role involves convincing and supporting colleagues, so the ability to translate complex energy questions into clear, usable solutions is central. Experience with batteries, hybrid systems, charging infrastructure or data analysis of energy use would strengthen a candidacy, as would familiarity with construction site operations. A practical, improvement-oriented mindset matters more than perfectionism.

Be specific about grid congestion. Rather than general statements about sustainability, describe a situation where you dealt with limited connection capacity, a peak load problem or an off-grid setup, and explain what you chose and why. The posting stresses switching between plan and practice, so give examples of both analysing energy data and standing on site to check whether a solution worked. Show familiarity with the technologies named in the posting, such as batteries, hybrid and off-grid systems and smart charging, and connect them to construction rather than abstract energy projects. Dura Vermeer presents itself as a family company with a long-term view, so mentioning how you bring colleagues along and share knowledge fits the culture described. Before an interview, think about a pilot or test you ran and what you learned from something that did not work first time, since the role values testing and improving over instant perfection. A short, concrete story here will stand out more than a list of certifications.

The focus is squarely on the environmental side of ESG, specifically the energy transition on construction sites. Grid congestion is the daily reality you work around, so much of the role is about matching demand to limited or absent grid capacity through batteries, hybrid generators and smart charging strategies. That directly reduces diesel use and the associated emissions from temporary power on building sites. Beyond carbon, your work supports Dura Vermeer's broader sustainability positioning as one of the more innovative construction firms in the Netherlands. Electrifying sites is a prerequisite for meeting climate targets in infrastructure and utility projects, so the role feeds into company-level decarbonisation goals and client requirements that increasingly ask for low-emission construction methods. There is also a social dimension: quieter, cleaner sites affect neighbours and workers, and demonstrating viable off-grid solutions can influence how the wider sector plans its own energy transition.

The main challenge is that grid congestion is largely outside your control. Grid operators may offer limited capacity or long lead times, so you frequently have to design around constraints rather than remove them, and explain to project teams why a simple connection is not possible. Balancing ambition with what is technically feasible on a given site is a constant tension. Another challenge is pioneering under pressure. Pilots and new energy concepts do not always work first time, and construction schedules leave little room for failure. You need to manage risk while still testing improvements, and bring colleagues along who may be sceptical of unfamiliar setups. Finally, the role spans multiple projects and stakeholders, so prioritisation and clear communication are ongoing demands. Data on energy use may be incomplete, and turning it into decisions requires judgement rather than a clean formula.

A typical day mixes desk work and site work. You might spend the morning reviewing the energy plan for an upcoming project, checking connection capacity against the expected load of electric machines and chargers, and adjusting the battery or hybrid setup. Later you could join a call with a grid operator about a temporary connection or a supplier about a charging solution, then drive out to a site to see whether the configuration actually works under real conditions. Because the role spans multiple projects, you likely juggle several at once, fielding questions from project leaders who need quick answers on what is technically and contractually possible. Data work also takes time: reading consumption figures, spotting peaks and turning them into practical adjustments. Expect variability. A pilot launch or an unexpected capacity problem can shift your whole week, while quieter periods go into planning and improving standard approaches.

As grid congestion remains a structural issue in the Netherlands, expertise in this area is increasingly valuable, and success in the role could lead to broader energy or sustainability positions within Dura Vermeer. The company is large enough to offer lateral moves into project management, work preparation or sustainability advisory roles. Leading pilots and new energy concepts gives visibility across projects and business units, which is useful groundwork for senior specialist or advisory positions. Building a track record of sites that run reliably on alternative power is a concrete achievement to point to. The permanent contract from the start suggests the company intends to keep and develop this expertise internally, so structured growth through the Dura Vermeer academy and internal mobility is a realistic path.

Inside the company, you work closely with project teams and site managers who need power that actually functions, plus colleagues in Materieel who supply and maintain equipment. You also interact with sustainability and work preparation staff who translate client and regulatory demands into project plans. Externally, grid operators are central because they control connection capacity and timelines, and their constraints shape what you can promise. Suppliers of batteries, chargers and hybrid systems are key partners in designing and testing configurations, and partners or subcontractors on projects depend on your advice for their own electric equipment. You are effectively the connector between technical reality on site and the people making commitments about timelines and sustainability, so clear communication matters as much as technical knowledge.
