Traineeship Offshore

Introductie

For October 2026, we are looking for trainees for various areas within TenneT: Operate, Onshore, Offshore, Design, and Digital & Technology Transformation. You can apply for one position only. This role is within the Offshore Division.

As an International Trainee in TenneT’s Offshore Division, you will help connect massive offshore wind farms to the onshore grid — a key step toward a clean energy future. Offshore is where innovation meets impact: we design, build, and operate the high-voltage connections that bring renewable energy from the sea to millions of households. You’ll be part of international teams delivering complex projects that expand Europe’s offshore grid and make the energy transition a reality. Every new cable and hub you help create brings us closer to a climate-neutral future.

Jouw rol

Our 18-month International Traineeship Programme is the ideal way to start your career in the energy sector. You will prepare for a future role in our Offshore division – where we develop, construct, and maintain critical infrastructure – while also having the opportunity to explore other areas of TenneT to broaden your perspective.

• A Tailored Journey – Three rotations, primarily in the offshore division, plus the opportunity to look beyond and gain insights into other areas of TenneT.
• Impact from Day One – Work on real projects that strengthen the grid and accelerate the energy transition.
• International Exposure – Collaborate across borders and see how onshore and offshore developments fit into the bigger picture.
• Learning Community – Join a network of trainees, experts and alumni, with training modules and internal consulting projects to boost your development.
• Shape the Future of Energy – You’ll join the organization that keeps the electricity system balanced 24/7, steers innovation in energy markets, and prepares our grid for more solar, more wind – and more complexity.

As a trainee for our Offshore division, you will contribute to projects such as:

• Designing of new transmission cables, substations, and offshore hubs that strengthen TenneT’s future energy infrastructure.
• Supporting Primary Technology leads on platform cables and switchgear by coordinating test activities and fostering alignment between suppliers and asset managers.
• Acting as Sub-Project Lead for an offshore wind farm interface, ensuring seamless technical and operational integration.
• Contributing to the 2GW program by supporting HVDC component design reviews and exploring innovative AI applications to enhance project performance.

Waar kom je terecht

Offshore is responsible for the development, construction, and management of the offshore electricity grid. With the North Sea as the green engine of the energy transition, Offshore plays a clear and vital role within TenneT’s organisational structure. The Offshore division manages the entire lifecycle of all TenneT offshore installations, from development and realisation to maintenance and handover to the Operate division. A crucial task is the construction of 2 GW offshore ‘sockets’, which collect and transport generated wind energy to the mainland.

Jouw profiel & achtergrond

We’re looking for graduates who want to build the backbone of the energy transition.

• Education – A Masters degree in Electrical Engineering, Maritime Engineering, Mechanical Engineering or Industrial Engineering & Management.
• Thinker & Do-er – You are results-oriented and bring both analytical thinking and action, using your project management skills to turn ideas into results.
• Energy Curiosity – You are fascinated by the challenges and opportunities for sustainable technology and large-scale infrastructure.
• Language – Proficiency in English is required, learning Dutch is not mandatory at entry, but learning Dutch will be part of your development during the traineeship.
• Flexibility – Open to travel and working at different TenneT locations.
• Residence – Because you’ll be working in the office 2-3 days per week, you need live in the Netherlands during the traineeship.
• Experience – Internships or relevant work experience are a plus.
