As a Mechanical FEA Engineer at BlueHeart Energy, you are responsible for performing mechanical analysis of the BlueHeart Energy heat pump. A first prototype is currently being produced and the company is now optimising it into a mass-producible design. You contribute to this by using FEM software to calculate which parts are the best for the heat pump.

When designing a unique heat pump, the Engineering team faces several technical challenges. The choice of the right materials is limited, as it depends on the internal pressure, the number of pressure changes and the internal temperatures in the heat pump. You support the team by analysing dynamic membranes, pistons, cylinders and structural components made of steel, aluminium and plastic. In doing so, you try to find out whether the parts meet all mechanical requirements and, for example, have long-term fatigue and creep resistance. Based on your findings, you advise the Engineering Team and indicate product optimisations.

You are part of the Engineering Team, which consists of several Engineers, a Designer, an Analyst and a Project Leader. You work closely with the Designer to develop an idea to a workable product. Furthermore, you will be working in a lively development environment, where you have the opportunity to be creative.

If you enjoy supporting a team by researching materials in depth, and find it challenging to do so within an organisation where there is a lot of change, then this is a job for you.

Working week

Structural Engineer

On an enjoyable day, you make a mechanical analysis of a heat pump component. Based on the results, you come up with a proposal for improvement, which you present to your colleagues and then discuss it with them.

On a less enjoyable day, you get stuck making the calculations, struggle with the software or fail to do qualitative analysis. Sometimes this is just bad luck, but you may also need to try a different approach.

Firsthand experience

You get the question from the Engineering team whether the strength of a pressure vessel meets all the requirements. How do you formulate an answer to this?

You first gather the information needed for proper analysis to determine the strength. What are the relevant pressures and temperatures? And what are the regulatory requirements? You process this information in a specification of the analysis. Then you determine whether it makes sense to outsource the analysis or to carry it out yourself: sometimes you do not have the resources to perform a good analysis yourself. In the case of outsourcing, you guide the relevant supplier. If you carry out the analysis yourself, you determine which software is most suitable for this purpose. You then perform the calculations and interpret the results, after which you report them and finally come up with a substantiated design proposal.


The growth path at BlueHeart Energy is not fixed. The company expects to grow rapidly in the coming years and create opportunities for everyone who is ready to take on new responsibilities. BlueHeart Energy offers training and courses and knowledge sharing between employees is very important. The great advantage of the start-up phase is that your own initiative is highly valued and you can create your own job. As Blue Heart Energy grows, you grow with it

Working at BlueHeart Energy

BlueHeart Energy was founded in 2016 to apply thermoacoustics as a technology in heat pumps. Thermoacoustics is a disruptive approach to generate heat and cold, with potential to revolutionize the whole industry. Over the past five years, BHE has developed a thermoacoustic engine to power heat pumps in residential buildings. This so called 'Blue Heart' of a heat pump is sold to manufacturers. In the coming years, Blue Heart will have to be further developed and optimized. Besides this, we must set up our production and strengthen the relationships with our customers.
