- Knowledge of ESG reporting frameworks (e.g., Corporate Sustainability Reporting Directive, European Sustainability Reporting Standards, Greenhouse Gas Protocol, Carbon Disclosure Project) is a plus
We know that you might not meet all the things on this list, but you might bring skills and experience that we haven’t even included here.
What we offer:
As part of the cooperation, we offer:
- flexible arrangements regarding the timing of the agreed activities, taking into account your university schedule;
- the possibility of performing the agreed activities from our office or remotely, as mutually agreed;
- opportunities to participate in team-building and other company events;
- an introduction programme to help you understand the relevant processes and get to know the people you will cooperate with.
