Job description

The battery cell determines what our systems can do: how long they last, how much power they can deliver and how they hold up after thousands of cycles. You are the one who finds that out. You set the research direction, write the test plans, read the measurement data and build models that predict how a cell behaves over the years. R&D and the system teams use that knowledge to improve and further optimise the modules we already have. From measurements to a better cell in the product.

At DENS we build clean energy solutions for the future. Your research does not disappear into a repost here: what you measure and conclude comes back in the modules we build. Short lines, quick decisions and measurement data from systems that are actually running.

We offer

• Room to grow: if you shown what your’re capable of, you’ll have every opportunity to develop yourself with us.
• A pleasant working environment where people work hard, but there is also room for fun
• Working with colleagues who want to move forward, keep improving, and grow with us

Your skills

• You are experienced in analyzing and interpreting bettery data.
• You know how to turn research into results: from test outcomes to tangible product improvements.
• You enjoy collaborating with different teams and sharing your findings.

Why DENS

• We are not a standard technical company. We are innovative, ambitious, and always on the move
• We look at what each person needs and respond accordingly: no standard approach, but tailor‑made solutions
• Because we all work on the same site, the lines of communication are short and decisions are made quickly; that is our strength

What will you do?

• Setting research direction and test plans— You decide where we focus our research and capture it in test plans: capacity, lifetime, performance under load and behaviour in cold and heat.
• Analysing and interpreting data— Raw measurements say little on their own; you extract what is really happening inside the cell and use it to back up our decisions.
• Modelling and simulation— You translate measured behaviour into models, so we can predict performance and ageing instead of testing every question.
• Evaluating new cell technology— New cell technology keeps coming to market. You assess what is genuinely suitable for our applications.
• Turning results into improvements— A test report is only finished once something is done with it: you translate outcomes into improvements and optimisations of the modules we already use.
• Working with R&D and system teams— You share your findings with engineering, BMS software and production, and liaise with cell suppliers on specifications.

Who are you?

• A university degree in electrochemistry, materials science, chemical engineering, mechanical engineering, electrical engineering or physics
• At least three years of experience as a battery or cell engineer, in R&D or a comparable technical research role — more experience is welcome
• Hands‑on experience characterising cells and setting up test programmes — capacity, cycle life, performance and behaviour under varying conditions
• At home analysing and interpreting battery data
• You can independently perform data analysis and develop scripts in Python or similar programming language
• Experience with experimental research, validation and R&D projects
• You know how to make research land: from test result to visible product improvement
• You are analytical, structured in your approach and result-driven
• You are scientifically curious: knowing that something happens is not enough, you want to know why
• Good written and spoken English, a good command of the Dutch language is prefered

What we offer?

• Salary that suits you — matched to your skills and experience;
• Enjoy your days off whenever you want — 26 holidays and 1 collective day, because relaxation is necessary;
• A tailored approach — we look at each individual’s needs and respond accordingly. No one‑size‑fits‑all approach, but solutions that fit you.
• Build with us — plenty of opportunities to grow with the organisation and develop yourself even more;
• Working with pleasure — a relaxed atmosphere, weekly drinks and fun team activities to make work extra fun;
• An inspiring and innovative work environment — with our own testing facility and R&D lab just a short walk away.

Why DENS?

If you choose DENS, you choose a working environment where innovation, sustainability and teamwork are key. With us, you will not only work on the future of energy, but also on your own. At DENS, you get the space to develop, to be challenged and to make an impact with us that will make a difference.
