Java Backend Developer (w/m)

We’re looking for a Java Backend Developer, who will join us in Software Development team and help us improve our product (LinkResearchTools) every day because we love to give our customers the best possible experience – to deliver WOWs.

You will develop in Java 8 with the help of Spring Framework. Most of our data is stored in Elasticsearch and Hadoop (Hive, Impala, HBase) clusters, but we’re also using MariaDB/MySQL and Redis. All our systems and services are running on Linux, so you’ll have a chance to get in touch with Linux, too. Docker & Ansible are next essential parts of our tech stack.

Besides that, you’ll have an opportunity to improve your domain knowledge in SEO (Search Engine Optimization) with our in-house training and certification programs by Christoph Cemper. Our company language is English, so German is not mandatory, but nice to have.
