Eindhoven
At Sioux Technologies it’s all about making the pieces of the puzzle fit together. And for this we need you, a passionate Senior Applied Physicist.

Sioux develops and produces state-of-the-art technology for the top end of the international high-tech community. Examples include a complex lithography machine, a compact electron microscope, a smart home automation system or an electric self-charging car. We raise the bar high and we often achieve the impossible. We do so together, as a team of enthusiastic electronics, software, mechanics, mechatronics and mathematics specialists.

Our position

Physics plays a central role in many Sioux projects, therefore, we are looking for an experienced applied physicist who can on the one hand contribute to the understanding of fundamental processes by modelling and performing experiments and on the other hand contribute to the design and realization of innovative high-tech systems. Fields of interest include optics, electron and x-ray physics, contamination, (ultra-)high vacuum and thermal design.

Your daily activities include:

  • participate in the entire product creation process from technology proof and concept phase to industrialization.
  • work on one or more projects at the same time and projects can take up to two years.
  • translate the wishes of the customer into system requirements.
  • play an important role in the choice of concept solutions: you know which solutions already exist, but you are also able to come up with new concepts if necessary. In this, you already take into account the manufacturability and maintainability of the product.
  • make functional models and test setups and if necessary, you are not afraid to pick up a screwdriver.
  • at the end of the project you support in verification of the design and the transfer to production.


As a Senior Applied Physicist, you are a Jake of all trades and you have excellent communication skills, both with internal stakeholders but also towards customers and suppliers. With your experience, you help to further expand the Physics & Optics group. In the design process, you guide colleagues from other fields to further develop and realize the design based on sound physical understanding. You are also able to guide junior engineers in their projects and coach them to further develop their (technical) talents.

  • experience in the design of one-offs as well as series production including industrialization

  • a creative mind that can think beyond the usual solutions and find the best solutions for our customers
  • a broad view of technology, with an eye on improvements in quality and working methods
