We’re looking for a Senior or Expert Backend Engineer to join one of our cross-functional teams, where iOS, Android, and Backend Engineers, Designers, QA, and a Product Owner collaborate with the help of an Agile Coach, helping millions of users discover new content. You will:

• Write high-quality and maintainable code. Test, collaboratively review, and ship it. Our stack is predominantly based on Ruby (Backend), Swift (iOS) and Kotlin (Android), but we’re always open to using different frameworks and/or programming languages.


• Follow and iterate on engineering best practice to achieve a robust code base, e.g. through code reviews and unit tests.


• Collaborate closely with Product and Design to build new features.


• Support other teams in finding pragmatic solutions that can be implemented in a reasonable amount of time.

Why you? We're looking for:

• Strong object-oriented design skills gained from 5+ years with backend services. Experience with Ruby, Go, Java-based or JavaScript preferred.


• Experience in building and delivering robust, scalable platforms tackling performance and optimisation problems to serve million customers worldwide


• Expertise with Rest APIs, modern database technologies at high scale and both testing and observability patterns


• Advanced understanding of different programming paradigms (OOP, Functional, protocol oriented), clean code, high quality tests, security as well as performance related topics


• Proficient in English and comfortable communicating even complex technical information. We work in a hybrid set-up, so clear communication is important for us.

It would be great if you could bring:

• Demonstrated ability to own and carry out a big project end to end involving complex decisions based on business and technological impact


• Feeling comfortable handling all layers needed (Mobile, Backend, DevOps) with common frameworks and languages


• Hands-on experience with AWS or similar cloud based services
