Job description

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.

Would you like to be a new member of the Laboratory team?

Our laboratory at IONCOR Salo factory is an industrial laboratory focusing on dimensional, electrical and material testing. Our Laboratory team is responsible of quality assurance measurements and measurement management in Salo factory. We ensure that measurement equipment and methods are according to standard requirements, monitor product quality by performing analyses, and support product development activities. Our team consists of operators in charge of daily analysis work, and engineers responsible of specific measurement methods and development.

As a Summer Trainee, you will assist laboratory engineers in laboratory development tasks, e.g., upkeep of work instructions and other laboratory documentation, and testing and analysis of measurement systems. You will also support the laboratory operators in analysis work when needed, ensuring that work is performed and documented in agreed schedule according to both customer and standard requirements.

The location of this traineeship is in Salo, Finland. Work is primarily on‑site, with occasional opportunities for remote work depending on the tasks.

We Hope You Have

• Ongoing bachelor's or master's studies in natural sciences or engineering
• Work experience in a laboratory environment
• Understanding of quality system requirements and quality assurance
• Ability to lead your own work
• Good teamwork and communication skills
• Curiosity and eagerness to learn from both theory and hands‑on work
• Good spoken English and ability to write technical documentation in English is required. Finnish language is seen a plus.

This Is What We Offer You

• Opportunity to join an agile and innovative team dedicated to driving the global energy transition through advanced battery solutions.
• With our Nordic heritage and expertise, we provide the chance to work on cutting‑edge projects across diverse industries, where electrification presents unique challenges, a good work–life balance and a feeling of creating something new.
• Flexible working hours
• An international atmosphere, with both Finnish and English as working languages
• Paid internship, with pay based on credits completed. Salary range is €2300-2750/month
• Trainee community and fun events throughout the summer
• Employee benefits such as free access to our gyms in Salo and Uusikaupunki, occupational healthcare, lunch benefit, and various discounts at selected stores and gyms.
