TELLONYM is a remote tech company, founded in Berlin. We want you to become part of our journey to build a social network that prioritizes open communication and lets everyone participate - and to help us build a world-class remote company on the way.

At Tellonym, you will be joining a young and diverse team with a variety of experience, skills and personal backgrounds. Everybody in our company can bring in ideas that will directly affect the millions of active users on Tellonym.

We believe in strong teams of self-motivated people, fast decision-making and empowering you to take charge through a supportive, learning-friendly atmosphere. We work in a flat hierarchy with the opportunity for everybody to weigh in. Every employee takes over own projects from the first day, which ensures quick learning, ownership and skill development.

Our backend is running on Node.js fully hosted on AWS. We use MySQL as our primary data store that is also self-maintained, but also make use of Apache Cassandra for feeds and ElasticSearch for search / text indexing. For caching we use basic Redis structures. We also run our own chat system that uses WebSockets for real-time communication. A large part of our system is our analytics services run via Clickhouse as well as our "worker" infrastructure to feature several async mechanisms in a scalable way.
