At Chimpy, we make people happy by making sure their smartphone never runs out of battery. Customers rent our solar-powered batteries at over 2000 locations in Europe, charge their phone on the go, and return them anywhere when they’re done.

Our vision is to make renewable energy & sharing resources much more convenient. Renting solar-powered batteries is a first step in this direction. Delivering an awesome user experience is a foundation of it.

We’re now looking for someone who believes in this vision, loves beautiful user experiences and wants to join us for this exciting adventure!

# What will you do at Chimpy?

  • Apply your love for UI/UX & code to create cool products
    We currently have two mobile apps, a bunch of small web apps and a lot of cool ideas in the backlog. There will be no end to stimulating challenges for someone with innate UX sense, technical ability and great taste.
  • Tackle real and impactful problems
    Our team is small, everybody gets to wear many hats. You’ll jump between design, product, marketing, code, architecture and quality. Your opinion will matter and boredom is not part of the deal.
  • Continue your growth as a maker at a fast pace
    The content of your job isn’t cast in concrete. We’ll fine-tune your role together, based not only on the company’s strategy but also your personal goals. No matter what skills you bring, you’ll get to flex a versatile set of muscles and will have the chance to level up.
  • Join us at a huere geil time
    We’ve been profitable since March 2017. We’ve started our international expansion this year from Switzerland to Germany, France and Austria. We’re taking part in more and more events & festivals. Growth has never been higher. And we’re creating a brand new front-end team in our office in Zürich, in which you’ll be the first member.
