Senior Infra/ DevOps Engineer (m/f/x) IoT

Sensorberg - Who?

Sensorberg is an innovative Berlin-based tech company that was founded in 2013.
We develop hardware and software for the digitalisation and automation of buildings. We specialise in solutions for storage, co-working spaces and commercial. We believe that a building is not just a building but a place where people spend more than half of their lives. Besides intelligent access systems, we equip buildings with a comprehensive digital infrastructure to provide occupants with the highest levels of safety, comfort and productivity, while enabling operators and owners to manage and utilize buildings with maximum efficiency.
We are a rather small company where people of different cultures and personalities come together and have (their) place. We are looking for people who share our vision and believe that a mix of qualifications, skills, personality and diversity is the basis for a transformative work process and the key to a successful system - in terms of people as well as technology. What we all have in common is a "hands-on" mentality, appreciation towards others and the ability to deal with (different) demands.
