Clean Energy for everyone.

Welcome to zolar! We’re on a mission to make solar power accessible to everyone and are proud to enable our customers to use the power of the sun in their own homes while making an active contribution to climate protection.

At zolar, we know that different people are successful in different ways, which is why we offer a hybrid working environment, meaning you can decide how much time you spend in our Berlin office, or how much time you spend working from home.
We strive for sustainability, we are ambitious, honest, and transparent, and we never want to stop learning or growing.

Will you join us in working towards a greener future for everyone?

Your role at zolar

The Tech team at zolar ensures that we create a customer-centric environment and a positive contribution to the climate. Our focus is to develop software that provides and enhances new - and in some cases previously untapped - opportunities for climate action and generates business value. Each of our development teams take full responsibility for a specific product, independently ensuring that the software is delivered quickly as well as functionally and completely.

Our tech stack at zolar consists of: PHP( Symfony ), MySQL, Kafka for the server side and TypeScript, React, Redux, node and React Native for our closs platform apps. Our cloud provider of choice is AWS and you might encounter AWS Lambdas, DynamoDB, S3, etc.

Get to know our team's tech stack choices better by having a look at our Zolar Tech Radar that lists our approach to languages and frameworks, platforms, processes and development tools we are looking to adopt or trial further.
