  • Contribute to software engineering best practices across the company.
  • Collaborate with other engineers, product owners, and designers to identify and solve challenging problems in the renewable energy space.
  • Support your colleagues to learn and grow by sharing your knowledge and insights openly and humbly.

  • You have experience defining requirements and acceptance criteria at a detailed level.
  • You have strong communication skills with both technical and non-technical colleagues.

What zolar offers you:

100% remote working possible // Stay flexible

Whether you want to save yourself the commute to work or want to see your colleagues in person – you are free to choose how many days you work remotely or in the office.

Workation // Stay curious

As a digital company, we believe you can do your work just as well from the beach house in Portugal or the winter cabin in Sweden. That's why you can work up to 4 weeks per quarter from anywhere within the EU.

Mental & physical health // Stay healthy

Your mental and physical health is close to our hearts. You can expect 30 days of annual leave per year in addition to a mental health program in cooperation with Mindsurance and a discounted membership in Urban Sports Club.

Company pension plan // Live well tomorrow

A world worth living in is a matter close to our hearts, which is why we offer our employees support in their private retirement planning with the help of sustainable providers and an employer contribution of 20%.

Benefitsy // You have the choice

You get a monthly voucher budget of fifty Euros in the Benefitsy portal at your free disposal (e.g. Spotify, REWE, Sixt, IKEA and many more).

Dog policy // Bring your own dog

A variety of four-legged feel-good managers provide natural entertainment in the office and enjoy the attention of their two-legged colleagues.

Buddy programme & (team) events // Involved instead of just employed

Get off to a great start – with a buddy by your side and regular team- & company events.

Tomorrow Bank // Sustainable Banking

Thanks to our cooperation with Tomorrow Bank, you receive the Change-model free of charge for 6 months and also support climate protection in banking. Instead of investing in coal power or weapons, Tomorrow invests the money into the future.

Remote work equipment // Ready for work

We want you to be able to work as well at home as you can in the office, so we provide you with a one-off budget to purchase a desk, chair or other things you might need for your remote work. You also have the choice between a Lenovo ThinkPad or Apple Macbook.

Clean energy for everyone.

Inspired by our love for the planet, we are creating a livable future for all humans through renewable energy. Our mission is to build a solar system on every roof in the world. We enable homeowners to produce their own green electricity and at the same time actively contribute to climate protection.

Let's shape the energy revolution together – become part of team!

At zolar, we strive to provide a friendly, safe, and welcoming environment for everyone who works here or with us, regardless of gender, gender identity and expression, sexual orientation, disability, physical appearance, body size, socio-economic status, ethic origin, national origin, age, culture, belief or religion (or its absence).
