Summer Trainee, Automation Engineer

IONCOR is an agile independent battery solutions company with Nordic roots and decades of experience as a leading partner for some of the world’s most admired brands. With a wide range of professionals in Finland and Germany, we provide modular battery products, customized solutions and contract manufacturing to energize a global energy transition. Buses, trucks, construction, material handling and agriculture are examples of categories where production volumes of equipment are lower, and end-use cases more complex and diverse, making a swift and viable transition a real challenge. This is where we come in.

We help customers master and gain maximal value out of battery technologies across the lifecycle, from early specifications and end-user support to reuse and recycling. This is how we electrify a global energy transition.

We are now looking for eager Summer Trainees to join our team. As a Summer Trainee, you can kick-start your career with gaining hands-on experience and be a part in shaping the future of battery technology.
