As a Product/Project Engineer at Blue Heart Energy, you are responsible for moving product optimisations into production. You work on component level that is used for our heat pumps. You manage aspects including development, calculations, production, theory and research. You work with suppliers and write specifications and documentation to control the development.

You look at new concepts and solutions and research them thoroughly, together with an (external) engineering team. The goal is to find multiple suppliers that can be valuable for the production of the heat pump. Therefore, it is important that you have strong communication skills, so that you are able to explain the added value of Blue Heart Energy and the product to these suppliers. And you discuss with the suppliers whether their technology can be applied to our product and how.

When you have designed and optimized the concept together with the supplier(s), you present that to the project team or steering board so that the actual development can begin. You also take a part in this development stage and testing solutions, but the focus lies on coming up with better solutions together with the project team and the suppliers.

You are part of the Engineering team and work closely together with, the Sales team and the Research team.

If you'd like to contribute to a start up that is currently shifting from development to production phase, and you find it challenging to think beyond the borders and add values from previous experiences, then this is the job for you.

Firsthand experience

You have to research technologies for the concept or component. How do you proceed?

You have to do research to find suppliers that will likely be of high value. After you have found some interesting suppliers, you reach out to them, pitch the company and product, and have initial talks on this. To support this, you can exchange some engineering data to gain an understanding of how suitable the solution is (or not). If you are still interested in working with this supplier, you can ask for a quotation or letter of intent, to see which prices and timeline they can offer. Based on this information, you decide if this supplier and Blue Heart Energy are a good match.


The growth path at Blue Heart Energy is not fixed. The company expects to grow very quickly in the coming years, which wil give opportunities all those who want it. BHE supports training and courses, and sharing knowledge is very important among employees. The main advantage of the start up phase is that you can create your own job. If Blue Heart Energy grows fast, you grow with them.
