Battery Test Engineer

Battery Test Engineer, battery testing and validation activities


We are recruiting new superheroes in our R&D team! If you want to work with an innovative high-power battery technology and if you feel like you can help us to take it to the next level, then we are waiting just for you!


What is this job about?

By joining Geyser as a Battery Test Engineer, you will be responsible for battery testing and validation activities. We know that there is a whole journey from an idea to a final product, and before the product reaches the customer, it needs to be tested and validated. In this job, you will design the test protocols, perform the tests and work closely with our R&D and product development teams to ensure the product performance. You are someone who knows how to work with statistical data and who is willing to learn and challenge yourself. To succeed in this position, you should have experience in testing and validation of battery or supercapacitor cells and modules and have a knowledge of the relevant equipment. However, if you believe that you have a translatable testing experience from another industry, we’d also like to hear from you. 


In this position your daily task list at Geyser Batteries could consist of:


  • Planning, organizing, and performing project-related validation activities.

  • Preparing and executing the tests, such as electrical, mechanical etc.

  • Working closely with our R&D team and product engineers to ensure that the prototypes match the specifications and requirements.

  • Designing the test protocols, performing the tests and working with our data analysts and other engineers to ensure the product performance


If you see that this could be your day, be sure to apply. While we appreciate your university/college degree in the field of electrical engineering, we are even more interested in you and your ideas and skills. Excellent English written and oral communication skills are a must to be considered for this position.

Who we are?


Geyser Batteries develops and produces a new class of high-power and high-cycling batteries, ideally suited for fast energy storage, especially in the power grid sector. We are financed by the leading Finnish industrial investors and supported by Business Finland.


Our technology is set to be a game changer in the transition to 100% renewables-based power grid by providing fast-storage batteries with a minimal cost per charge, lowest in class greenhouse gas emissions, maximum safety and ease of recycling.


Having started at the end of 2018, we are now working for and with major customers and partners, like Shell and Fraunhofer, and are active in various research&innovation organisations at the European level.

What we offer?

We pay at market rates. Our growth expectations are remarkable and based on your personal growth and success in the position, you may expect your role to evolve accordingly based on your interests and skillset. Long-term financial and organizational compensation can be expected in this start-up environment.

As a company, we are always curious, eager to learn from each other, and foster new ideas to grow as a team towards the new heights. Our team is diverse, energetic, and supportive, and we come to work every day because we see how big an impact we are going to make on the global transition to a sustainable power grid.
Work will be executed at our R&D Center in Mikkeli, Finland. Starting time of vacancy is to be agreed.
