For April 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.

Your profile and background

  • Education – A Masters degree in Electrical Engineering or Industrial Engineering & Management.
  • Thinker & Do-er – You balance analytical thinking with 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 to live in the Netherlands during the traineeship. You’ll also join us in person for the recruitment day as part of the selection process. We’re looking for graduates who want to build the backbone of the energy transition.
  • Experience – Internships or relevant work experience are a plus.

Your contribution to TenneT

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 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.
