About Chimpy

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 and sharing resources much more convenient. Renting solar-powered power banks is a first step in this direction.

Software Engineering at Chimpy

Chimpy is not your typical software company – we make our money with physical products. All this wouldn’t be possible without our software engineering team. Retailers, from large international chains to small Mom-and-Pop shops, rent out Chimpy powerbanks by using our software platform. Our internal refurbishing operations run smoothly thanks to our custom logistics software. Users find and rent Chimpys using our mobile apps. All this we do with a team of four amazing engineers, so your work really really really matters.

About the job

  • You work with a small but excellent team on software which helps make millions of people happy (who likes dead phones?) 🔋
  • Unlike in big companies, you don’t work on small irrelevant projects. Your contributions have a direct effect on the product our customers use. More than that, your opinion matters. A lot. 🌎
  • We value freedom. There are no fixed working hours, and people can choose to work from the office, from home, their favorite coffee shop, the train or on a boat. If you get your best work done on a boat, that’s what counts ⛵️(we still think some shared time in the office is important, so this is not a remote position)
  • We’re growing fast internationally and our software rental platform needs to grow with us. Your job includes to think about, design, and develop new features to support these growing needs. 📈
  • Obviously, you’ll be working closely with our CTO, Sag. People say he’s a fun guy. You’ll discuss software architecture & design, programming paradigms, infrastructure & technology choices. And of course, roll back your sleeves and implement these ideas, too. 👨‍💻

Your personal growth is key. Therefore, you won’t be presented with a fixed set of tasks, but based on your interests be able to focus and learn about new things, as well. Want to dabble with UX? Learn more about data analytics? Check out serverless computing? Hey, who are we to judge? 😃
