Why YOU should join our team?
Most companies offer a good work-life balance or nice team events or a ping pong table and free drinks. These are nice benefits, but when you work 8 hours a day, what really matters? At CellSense, we see your individual problems as important. To combine work and personal life, you need flexibility. That means flexible working hours (you can start your workday at 4:00 am or at lunchtime if you want), home office if possible, no time tracking. The only thing that matters is to find solutions, crack the problems and make the customers happy. We are a growing, international, owner-managed company with a focus on cool technology. Very importantly, there is no “upper class mentality” in CellSense’s management. We have an open ear for all team members. We have a flat hierarchy with short lines of communication.Of course, we also find time to celebrate successes. Barbecues, Christmas parties and team events are part of our company culture.
