Northvolt is looking for a Validation Engineer Intern in the mechanical validation group to be part of our growing team. This is your chance to contribute to the development of the world's greenest Li-ion battery cell.

You’re interested in mechanical battery simulation and testing? Then you could play an integral role in the validation and qualification of our safe, reliable, high-energy battery cells. We are looking for a team member to develop a simulation model for battery cell housings to predict the failure mode during high-pressure exposure under various environmental conditions. The task includes the development of a simulation model, the setup of a test method to validate modelling activities, data analysis and presentation. Furthermore, you will support other project-related testing activities. You will work with a broad perspective from high-level prerequisites and concept development to project planning, development and delivery.

Key responsibilities include but are not limited to:

  • Develop a high-pressure simulation model for battery cell housings
  • Develop a test setup to validate simulation results
  • Arrange test activities and sample analysis in close collaboration with production, cell design, validation, test as well as quality department
  • Support other project-related testing activities
  • Ensure delivery of the project activities
  • Analyze and present test results
  • Help the team to perform and innovate

Apply with CV in English and cover letter, or your complete LinkedIn profile. The role requires traveling within Europe.

About the company

Northvolt makes green batteries for a blue planet. Affordable cells and high-quality battery systems. All manufactured with a record-low carbon footprint. Purposely built to provide Europe with the opportunity to switch to renewable energy – efficiently and entirely.

To accomplish this, we do things differently. We design, manufacture, and recycle everything under one roof. We even build our own factories. All this is incredibly challenging and requires us to think in unconventional ways. We’re constantly experimenting, learning and adapting to make batteries so great – they will one day make oil history.

Northvolt is growing fast. We’re staffing our international office in Stockholm, our R&D facility, Northvolt Labs, in Västerås, as well as our Gdansk facility for production of battery systems. We're also hiring for our gigafactory Northvolt Ett in Skellefteå, Sweden. We want to work with smart individuals from all disciplines. Strong individuals that truly want to make a positive impact on the future. Those of us already on board share a passion for our mission. We’re prepared to work hard in pursuit of excellence. We enjoy the ride and our main drive is to make a difference for real. As a team, we’re dedicated to thinking new, working hard and having fun.
