Embedded Junior Firmware Engineer Bachelor/Master, Cleantron – Amsterdam (NL)


About the job

Embedded Junior Firmware Engineer Bachelor/Master

Are you interested in working for an innovative and growing business?

Are you interested in developing lithium-ion batteries for different applications?

Then we are looking for you.


Cleantron develops and produces lithium batteries close to Amsterdam in Nieuw Vennep. Cleantron batteries are used in a variety of markets, at home and abroad. Think of electric vehicles such as special e-Bikes and e-Scooters, Light Electric Vehicles, Automatic Guided Vehicles (AGV’s), Automotive applications and Construction Equipment.

We put the quality of our products centrally and in order to guarantee this, we continuously work on improving our product designs and production processes.

Good battery design is very important for manufacturability, safety and battery life. Cleantron is developing batteries for new applications where these aspects are key.

The embedded Battery Management System (BMS), together with the Lithium-ion Cells, form the heart of a Cleantron Battery and guarantees the safety and service life of the Battery. The BMS ensures, among other things, protection against many extreme conditions (over-voltage, under-voltage, over-current, etc.). In addition, various important data for the customer are collected and calculated, such as the “State of Charge” and the condition of the battery. Finally, based on customer-specific protocols and interfaces, the BMS provides communication between the battery and the battery application. This often must be coordinated with the motor controller or VCU of the vehicle or application so that in an extreme condition (for the battery) the vehicle stops safely or that in an imminent extreme condition the motor controller regulates back in time to prevent the battery from switching off.
