  • You will participate in all stages of the software enable development lifecycle, from designing and documenting systems, to writing code and automated tests, to planning, managing, and monitoring production software deployments.

    You will work with a wide range of technologies and programming languages, including Go, Rust, Python, ClickHouse, Kafka, Salt, PostgreSQL, Grafana, Kubernetes, and more.
