As an R&D Materials Science Engineer at BlueHeart Energy, you will be responsible for understanding the functionality and performance of the polymer components of the thermoacoustic heat pump to define the design space. This includes comprehending component interfaces and interactions with the rest of the system. You will play a key role in defining high-level component architectures, setting component roadmaps, and developing solutions based on system-level component requirements. Collaborating closely with Engineering teams during the development phase and test labs during prototype build phases will be part of your responsibilities.

You will utilize various software tools to model and validate components, ensuring their optimal performance. Additionally, you will have an overview of design, performance, and production, including the development of component maturity for mass production. Setbacks and adjustments are part of the job, as each component is handled individually. You will work with colleagues and make necessary adjustments to ensure the components work effectively within the machine.

The R&D team at BlueHeart consists of six engineers, including the R&D manager. You will also work as part of an engineering team with additional engineers and a Product Owner. In terms of reporting, within the engineering team, you will present your work to the Product Owner. If you are working on modeling or new projects, the R&D group and the Product Owner will have oversight. This process involves an iterative approach, with regular presentations to the larger group every three weeks to ensure alignment and progress.

If you enjoy being creative, learning new things and you don't mind dealing with experimenting and feedback, then this is a job for you.

Working week

R&D Engineer

On an enjoyable day you’re modeling a new concept and are brainstorming ways to build a prototype. You’re also analyzing data from recent experiments to conform a new idea.

On a less enjoyable dayy you’re dealing with a supplier that isn’t able to meet requirements. You need to review documents from previous work, which gives you a delay in your work.

Firsthand experience

You need to get a specific material property that is not well understood in the literature. What do you do?

At first you do a literature review to see what similar data is available and how it is characterized. Then you develop a test methodology and design a fixture. You work with the supplier to get test samples and after that, you perform experiments and analyze the data. Finally, you update your model with the new research and findings.


The growth path at BlueHeart Energy is not fixed. The company expects to grow rapidly in the coming years and create opportunities for anyone ready to take on new responsibilities. BlueHeart Energy offers training and courses and knowledge sharing between employees is very important. The big 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.
