Job Details

Mechanical engineer for particle accelerator applications

  • be part of an international team developing a high power superconducting proton accelerator;
  • perform the integration of a particle accelerator;
  • Perform technical coordination;
  • familiarity with a 3D CAD software (Creo, Ansys);
  • Engineering.

We are ready to build this accelerator. Are you?

Together with a large team of ambitious engineers and researchers, SCK CEN wants to develop new medical radioisotopes to treat cancer patients and solve the nuclear waste issue by means of the MYRRHA project ( The MYRRHA project’s first implementation phase (start of commissioning scheduled for 2027) consists of a ≈170m long, superconducting, high power proton accelerator with one of a kind reliability and two target facilities for research into radioisotopes, radioactive ion beam physics and nuclear fusion reactor materials.

To help us achieve our ambitious goals, we are looking for a new team member to join the “Accelerator mechanics” group to perform mechanical design and study activities for the particle accelerator. While some accelerator components are still being designed, others are already being procured to be ready in time for installation starting in ≈2025.

You will work closely together with a CAD designer and with the support of the accelerator system experts, ATS project officers, and you will:

  • perform mechanical studies for accelerator mechanical component – static structural calculations, fluid simulations, thermal condition studies;
  • check mechanical integrity of complex assemblies of the accelerator components. Control of mechanical tolerances, constrains and materials of the accelerator components and assemblies;
  • develop the strategy for mechanical safety and reliability for components of the accelerator;
  • design (with help of the CAD designer) specific components, girders and supports of the accelerator;
  • perform technical coordination between the groups and units regarding mechanical related topic;
  • participate in the transfer and installation of a beam line test stand. The beam line test stand is currently installed in Louvain-La-Neuve;
  • develop and implement an overall mechanical safety and integrity strategy together with the group/unit head. (installation ≈2025 - 2027).

To join this frontier, you’ll need

  • a Master in Mechanical Engineering (mechanical, mechatronics) or equivalent;
  • minimum 5 years of experience as an engineer;
  • experience in the standardization of the mechanical parts (requirements, procedures, materials, treatment);
  • experience in the design of specific and complex machines is considered a strong asset;
  • experience in systems engineering is an additional asset;
  • familiarity with a 3D CAD software (Creo, Ansys);
  • familiarity with international standards;
  • knowledge of mechanical calculations (structural, CFD (strong asset), thermal);
  • experience in writing of technical documentation;
  • the ability to speak/write fluently in English;
  • to be a self-managing team player with an eye for detail and a structured work approach.

We explore. Driven by our passion for science. Boosted by our unique infrastructure. We sound out the frontiers. We expand our knowledge in various nuclear areas. However many horizons we may explore, we always pursue the same objective: developing innovative applications for society.

Why work for us
At SCK CEN, we are on the forefront. By developing new knowledge and innovative applications, we move the line of what nuclear science can do for society. Each day, we are driven by a relentless ambition to build our expertise and achieve our goals. We are immersed in a world of unique technology, open discussion and discovery, together with other capable and curious minds.

SCK CEN works actively on the design and construction of a new multi-purpose research plant: MYRRHA (, which stands for Multi-purpose HYbrid Research Reactor for High-tech Applications. MYRRHA is a versatile research infrastructure but above all, unique. It is the world’s first research reactor driven by a particle accelerator. The special feature of this unique configuration – Accelerator Driven System (ADS) – is the “subcritical” core of the reactor. The core does not have enough fissile material to spontaneously keep the chain reaction going.

So that’s why we have to build the most reliable super conducting high-power proton linac in the world. A linac can be designed with fewer interruptions in the beam’s proton flow than a cyclotron. While the accelerator will be almost 300 m long and reach 600 MeV proton beam energy in the final configuration, the first stage is limited to 100 MeV. This project part is called MINERVA and is in full development. It will allow the demonstration of the required reliability concepts and at the same time it will be used to deliver beam to users in two experimental irradiation facilities.

The aim is to be able to beam-commission the installation in 2027 so as to start with the development of innovative medical radioisotopes and perform fundamental research in physics. In the next phase, we will aim for an energy level of 600 MeV. In the third phase, the research reactor will be built. So we have a lot of work to do.

What we are looking for

Are you searching for a challenge that contributes to solving some of society’s most important issues, such as closing the nuclear fuel cycle, transforming the lives of cancer patients or conducting fundamental physics research? Don’t look any further and apply.
