Do you want to contribute to the development of a new energy technology that can safely turn nuclear waste into emission-free energy? Are you excited about working in a hands-on deep tech start-up team that aims to make a huge impact? Do you like complex challenges? Then, we might be just the company you are looking for!

We are looking for a driven Process Engineer to join our innovative and international team.

About Thorizon 
At Thorizon, we’re a passionate team of ~ 40 spread across Amsterdam and Lyon, all working together to develop nuclear power solutions. We design and create frontier technology for Molten Salt Reactors (MSR).

Our purpose is to accelerate the availability of clean energy and help solve the climate crisis.

We are in the development phase and aim to solidify our design through analyses, experiments, simulations, and partnerships. At Thorizon, we believe a strongly coupled multidisciplinary technology development requires a culture of full openness and transparency. That’s why we foster values like unity, communication, and support to ensure we grow together as a team while achieving our purpose.

• You like working in an agile manner and are comfortable at the fast-moving pace of a technological scale-up
• You have an intrinsic motivation to work for Thorizon.

What can you expect from us?

• Dynamic and ambitious team of nuclear technology professionals that are committed to solving today’s energy challenges.
• Unique experience in a fast-growing VC-backed deep tech start-up
• Opportunity to work on a game-changing technology that reduces our carbon footprint and nuclear waste streams.
• Competitive salary and an employee profit-sharing plan
