Senior Java Software Developer with experience in designing and working ...

Our new APSIS One platform is built from the ground up using brand new cloud-native technology and methods. We are now looking to strengthen our Audience team, who builds the core data processing and storage layers in our platform. This domain involves advanced data intensive systems engineering including managing a complex environment of AWS cloud infrastructure. It includes working with databases of many flavors, managed and self-hosted on EC2, and managing multiple distributed systems and data processing pipelines with very high demands on performance and correctness.

APSIS aims to work at the forefront of technology and development. We follow modern agile practices with cross-functional DevOps teams, where each team assumes complete technical and operational ownership of their applications, including not only implementation but full architectural design and tech selection, QA, continuous delivery, and technical production environment operations. We believe in small, highly skilled, highly empowered and autonomous teams taking maximal ownership of their systems. We believe in DevOps as a culture rather than a specialised role.

In a typical day this role will be working in close collaboration with team members and other similar teams in Stockholm, Malmö, Warsaw and Russia. The team has a dedicated Product Owner and Development Manager and its own backlog of stories and tasks. The team members participate in writing, grooming, prioritizing and working together to bring it all the way to a scalable production deployment. 

To facilitate the DevOps way of working all APSIS dev teams are granted “20% time” where the team works outside the product backlog on tasks of their own choice, among other policies.
