Help build a more intelligent, sustainable and resilient society.

The Job - (Junior) Transition Consultant

Are you enthusiastic about having a positive impact on society? Are you ready to put your strong quantitative skills into use by furthering some of the most challenging transitions?

At Kalavasta we work on discovering and realising sustainable equilibria. We develop insights and models on complex issues which enable people and organisations to make changes towards a more sustainable and resilient society. Our main focus is on the energy transition, although we have also become active in the agri-food-nature transition. Recently, we have focused on the development of two systemic, integral and transparent transition models: the agri-food-nature transition model (ATM) and the carbon transition model (CTM) for the energy-intensive industry. We published these models in Q4 2022, continue to develop them and use them to execute strategic projects of the highest level to explore and help realise systemic change. An example of such an application from earlier this year is the development of climate neutral energy scenarios for the grid operators’ investment outlook for 2050.

We are looking to expand our team with a junior transition consultant who will work on a variety of projects together with our team, partners and clients. Your activities may include but not be limited to developing models, conducting (scientific) research, meeting and/or discussing with technical experts and clients and attending conferences.

Tuuli Tiihonen, Transition Consultant since June 2019, about her experience:

"Working as a junior transition consultant as Kalavasta boils down to two things: being passionate about helping steer our society towards a more sustainable equilibrium and making sense of the complexity that currently stands in the way of doing so. In order to be able to contribute to the work Kalavasta does, you will develop an understanding of complex systems and model them, whether they are biological, physical, or financial in nature. Due to the large variety of projects, picking things up quickly is a must, as is an interest in a large number of fields. Having some Excel skills does not hurt either. This job requires you to be able to work independently, taking care of your own time management. As a junior transition consultant at Kalavasta, your work already has a real impact. You will also be challenged to bring your skills and knowledge to the next level each and every day. One of the best parts is that you get to work with and learn from some absolutely brilliant people."

At Kalavasta, we want to give our people the freedom to work in a way that suits them the best. For us this means that we do not have a fixed office. We work from home most days but meet up periodically on ‘office days’ to work together. You will also have meetings with clients and partners on average once a week. We expect you to find the way of working that enables you to bring the best results, whether this means taking advantage of a good concentration very early in the morning or improving your focus by taking a walk or doing some sports in the middle of the day.
