Job description

We are seeking a one year temporary Cell Validation Engineer to join our Cell Development team at Altris, where we are pioneering the next generation of Sodium-Ion battery technology. This role is centered on cell-level testing and analysis, and is ideally suited to someone who enjoys working at the interface between early-stage prototype development and scale-up to larger-format cells.

As a Cell Validation Engineer, you will work in the core of Altris – where battery cells are manufactured. You will work with the cell validation activities to confirm performance, safety and reliability of cells against project requirements, ensuring readiness for customer delivery and scale-up.

The Cell Validation Engineer reports into the cell development team and is responsible for conducting a wide variety of tests on battery cell level. The primary focus is in-house electrochemical testing, however the role extends to covering externally conducted tests (electrochemical, environmental, safety, abusive and certification testing). The cell test engineer will collaborate closely with the cell development team to design tests, prepare cells for testing, execute the test and report the results in an efficient way.

You will work in a modern workplace with a new innovative battery technology with the aim of enabling the transition to a carbon free society.

Main Responsibilities

• Responsible for full end to end cycle of testing on cell level (R&D Samples and Production samples) from planning through to reporting
• Prepare test protocols and scripts in accordance with customer requirements and internal requirements
• Preparation of the DUT (Device under test) including but not limited to: additional sensors or measurement devices, planning test channel allocation
• Executing on the test whilst keeping safety as a number one priority
• Reporting results and drawing conclusions. The individual shall be very strong in documentation and have a desire to standardise the data handling and reporting
• Summarise test results, draw conclusions in close collaboration with cell development engineers and communicate results in an effective way through reports and presentations internally and for customers.
• Identifying, executing and managing tests with external partners (environmental, safety, certification etc).
• Ensure that our validation equipment is maintained regularly and kept in great conditions, including testing channels, temperature chambers and computers controlling the systems.
• Participate in root cause analysis if the formation and aging (F&A) cycles are out of specification for the pilot scale production

What We´re Looking For

At Altris we value individuals who are keen to learn and develop their own skill set. If you're a problem solver who loves batteries and making complex things work, then this is the place for you. Beyond that we imagine that you have some of the following points on your resumé:

• Engineering Degree (any area, but preferably with a battery focus)
• 4+ years Practical experience working with cell validation is required with experience ranging from designing tests, executing tests, analysing data and reporting results.
• Basic understanding of battery cell components (cathode, anode, separator, electrolyte etc) is required
• Experience with data handling and drawing conclusions from complex data sets, preferably trough scripts, data bases and other ways to systematise the data.

What You Will Get

We can promise you that you will be challenged, develop your skills and have the opportunity to work with truly amazing and competent colleagues. If you like changes and want to set new processes and ways of working - this is the place for you!

Diversity and inclusion are very important to us and we are committed to creating an inclusive work environment. We want to be a workplace where everyone’s perspectives and opinions are valued, and we are dedicated to creating opportunities for all employees to thrive and reach their full potential.
