Moreover, we enable you to use more renewable energy in your premises, contributing to a cleaner and greener future.

  • You will create plans and take ownership to successfully deliver a new product functionality or feature.
  • You will be performing technical reviews for new and existing energy storage systems including individual components or related equipment.
  • You will support the operational team providing technical guidance and ownership for problem solving.
