At the earliest date possible we are looking for support for our #teamsonnen

At sonnen, we believe clean, affordable, and reliable energy for all is one of the greatest challenges of our time. With over 40,000 sonnenBatterie-systems installed worldwide, sonnen is a proven global leader in intelligent energy management solutions providing greater energy control for residential customers through increased solar self-consumption, reduced peak energy usage and reliable backup power during outages – contributing to a cleaner and more reliable energy future.

sonnen has won several awards for its energy innovations and sonnenBatterie products, including Fast Company’s Top 10 Most Innovative Companies in Energy, the 2017 Zayed Energy Innovation Award, MIT’s Technology Review’s 50 Smartest Companies in 2016, Global Cleantech 100 for 2015-2017, Greentech Media’s 2016 Grid Edge Award for innovation, and Cleantech’s 2015 Company of the Year Award in both Israel and Europe.

Some examples of what our team did in the past:


  • Connected tens of thousands of IoT devices to our cloud service
  • Published several state-of-the-art web portals along the whole user journey for our customers & partners (React, AWS microservices)
  • Published sonnen’s own Amazon Alexa voice assistant skill
  • Developed and published the sonnenGlobe (globe.sonnenbatterie.de), our online explorer showing thousands of people already profiting from clean and affordable energy
  • Published both native Android and iOS apps for customers which let them see live how their sonnenBatterie and sonnenCharger are doing




  • work in a cross-functional, feature-driven engineering team distributed across Europe
  • contribute across the stack with a customer-focused mindset to deliver new functionality 
  • build scalable, reusable components in a React (or React Native) frontend and extend APIs written in a Ruby on Rails backend in a distributed system (Salesforce, IoT platform, 3rd party APIs)
  • continuously monitor services
  • optimize and refactor code as well as designing systems for scale
  • use JavaScript, React, Ruby on a daily basis
  • collaborate with teammates through planning, pair programming, testing, and delivery of the features you build




We’re looking for someone who is curious and interested in learning, brings good communication and teamwork skills, and helps others grow by sharing their expertise and encouraging best practices. If this sounds like you, here’s the additional experience we’re looking for:

  • experience across the stack and familiarity with APIs and distributed systems

  • understand the value of testing
  • experience using agile/lean development practices with a focus on incremental delivery and business value
