We offer

An exciting position at the heart of the product business and with a very central role in the development of Climaider.

You can see a direct effect of your actions and the role you fill. There is a great development opportunity in the role and you will both develop your personal skills and have the chance to have a prominent role in the journey of a growing startup with global ambitions.

We are an impact and mission-driven startup and you can expect a fair salary, but compensation to be weighted towards warrants over salary.

We expect you to put in your best effort and to work hard for your designated hours. We do not however believe in the startup 100-hour workweek myth at all. You can expect an average 40-hour workweek with us and no pressure to work more than that. We want you to put in the best work you can and we’re very flexible in accommodating your needs in that regard.


At Climaider we treat each other like family and we invite you to become a part of that. There is no pressure to stay beyond work hours but if you are interested to join, we very often do stuff together outside of work, whether just hanging in the office late afternoons working on passion projects or doing stuff together on the weekends.


Our office is based at Blågårds Plads, Nørrebro. We would love to have you around as much as possible, but if working remote does it for you, there’s no obligations of being here.

We hope the above has captured your interest, if you have gotten this far. We would love to hear from you, if that is the case. For further questions, please feel free to reach out.

For more information or questions please contact us.
