Intro

exnaton is a startup, spun out of ETH Zurich, which offers software for renewable energy to utility companies. Our software enables energy providers to set up energy communities and smart energy tariffs in their distribution areas. Users of our software can track their energy consumption and buy renewable energy from their neighbours, which makes investing in the energy transition simple and fun!

Prosumers, dynamic electricity tariffs, and energy sharing are driving the energy transition and becoming integral components of the decentralised energy world. Our software is a cloud application that processes smart meter data and computes smart real-time prices for locally produced energy, which makes renewable energy financially more attractive. End-users receive an app that maps the sources of their energy, making their electricity consumption more understandable.

Our team is growing, and we are looking for extraordinary, talented, and motivated people to complement our team. We are a diverse team of engineers and business developers, all driven by the shared goal of using technology to create a sustainable impact in our society. If you're enthusiastic about contributing to this exciting journey, we invite you to be a part of our innovative and skilled team.

  • Assist with travel bookings for selected in-person meetings

  • Support onboarding logistics and order devices for new colleagues

  • Maintain employee documentation and keep HR system (Personio) up to date
