We are building a sophisticated OLAP/SQL query engine for advanced analytics, accessing data from many different data sources (RDBMS's, Hive, Impala, Druid, Elasticsearch and others). The query engine is written in Scala and builds on Apache Calcite. We are planning to open-source it during the course of this year with the goal of making it an Apache project eventually.
The project involves working with many interesting concepts related
to data processing and querying such as query parsing and validation,
relational algebra, creation of logical and physical plans and adapters
to different database and execution engines. Your work will also involve
participation in the communities of and development of contributions to
Calcite and other open-source libraries we use.

We strongly believe in the importance of uninterrupted time to get stuff done. You own your features, from spec to implementation to operation. We believe in competitive compensation, and quality over quantity when it comes to working hours. We provide you with the hardware you need to be comfortable and productive. We offer free public transportation and support you during the whole process of relocation (we are pros: 95% of us have relocated to Berlin).
