Our problem statement is not straightforward, as we aim to achieve high-end results in all important technical aspects of our business:

- best availability,

- lowest latency in every micro-service,

- the most efficient resource usage.

If you're a product-passionate person, your mind is keen to solve deep tech engineering problems, you have a fast "PoC first" approach with a deep sense of ownership, and you're happy to reach into the UI when needed, we would love to hear from you.

- Operations: observability (APM, RED signals, SLO alerts), GitOps delivery via Helm and ArgoCD.

- A "whole feature" mindset — willingness to own delivery end-to-end, including the UI, rather than handing it off

Benefits:

- Work on meaningful data products and shape them with your vision.

- 25 vacation days + 15 sick days + 1 birthday leave.
