## Description (the employer's text)

### DAILY PLAYGROUND

In this position we are looking for a jack-of-all-trades database driver and ecosystems engineer, who would love to work together with the FLOSS community and our core team to support it on drivers and adapters for CrateDB, a distributed time-series database. 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.

WHAT YOU GET OUT OF THIS OPPORTUNITY

- Join a leading VC funded tech company from the pre-B stage through the exit
- Benefit from a welcoming and supportive working climate
- Be part of an open collaborative culture with “Craties” from diverse backgrounds
WHAT YOU’RE RESPONSIBLE FOR

- Develop and maintain
- Drivers for CrateDB (JDBC, Python/SQLAlchemy, etc.)
- Connections to external tools (Grafana, Tableau, Airflow, etc.)
- Internal administrative tools (crash CLI, Admin UI)
- Improve PostgreSQL-compatibility of CrateDB and its ecosystem
- Migration tools from/to other databases systems and storage formats
- Write and maintain technical documentation like reference architectures, integration examples, etc.
- Work and interact with your Open Source community and technical partners on joint projects
- Support our Product Managers with technical requirements
### YOUR SKILLS

Applying craftsmanship (mfx) to continuously improve and take over responsibility for existing code bases

Knowledge about standards and protocols, and what they are used for. Not limited to - but we use - HTTP, PG Wire Protocol, Python DB API, and JDBC

Good knowledge of at least Python and Java, and preferably experience with additional languages like Rust, C++, Golang, Swift, or Zig

Experience with test driven development

Knowledge about versioning, packaging and shipping (in a polyglot software environment), and how software is operated in production environments

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

### NICE TO HAVE

Existing Open Source contributions are valuable but not a requirement

Knowledge and/or experience with message bus systems like AMQP, Kafka, MQTT, or ZeroMQ, and their corresponding broker implementations

Knowledge and/or DevOps experience in containerized environments (Docker, K8s)

### WHAT WE OFFER

- Remote workplace: We can offer you a direct position at one of our entities in Germany and Austria or through Remote.com in your home country
- Competitive compensation
- Flexible working hours
- A variety of perks (flexible holidays, fitness, education)
- Participation in our Employee Stock Options Plan
At CrateDB, we don't just accept different - we celebrate it and support it. We are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, or gender identity.
