REMOTE - Croatia, Germany, France, Lithuania, Netherlands, Poland, Sweden, UK INTRODUCING CHAPTR
Ask a room of people to define the future of work, and you’ll likely get a dozen different answers. For some, it’s about focusing on more creative goals and automating daily tasks. To others, it creates a fear of being replaced in the near future. To us, the future of work means working alongside AI. Being in control of the best technology instead of being controlled by it.
CHAPTR is a part of the Holtzbrinck Publishing Group alongside businesses like Springer Nature, Digital Science and Macmillan Publishers. A dynamic startup fueled by our passion for technology and redefining the future of work. We build cutting-edge products and relentlessly push the boundaries of what is possible.
We're actively building a diverse team, because diversity fuels fun and innovation. If you feel you may not meet all job requirements, apply anyway; we understand impostor syndrome but won't let it hinder hiring the best. We're a remote, #familyfirst company, offering flexibility while staying committed to our mission. If you're excited about innovation, eager to propel our projects, and passionate about AI, join CHAPTR on this thrilling journey.
