You will be working directly with some of our founding engineers, mostly on projects managed on public GitHub. We need your help to develop and maintain drivers and adapters for CrateDB, and also contribute to 3rd party applications and frameworks to improve their integration capabilities with CrateDB, very close to other open source software projects like SQLAlchemy, pandas, Dask, Apache Kafka, Flink, Superset, Airflow and Grafana, just to name a few. You see that we are looking for someone who lives and breathes open source.

- Comfortable working with relational databases and SQL
- Strong debugging and problem-solving skills
- Self-directed, hands-on engineer, who can dig through all the obstacles involved in driving specific development efforts forward, in a "Fullstack" manner, assuring software quality, documentation, and communication, to finally ship the software component at hand
