Senior DevOps Engineer - Highload, Cloud & Data-Intensive Systems; EU​/Remote

About The Project

The team develops and maintains distributed services around analytics, APIs, and transaction monitoring. The systems process very large volumes of data — terabytes of storage, trillions of records, continuously growing load.

• 100 servers (bare metal + VPS)
• active use of IaC
• Kubernetes clusters in production
• focus on stability, observability, and automation

• 60% — operations and incidents (including helping teams)
• 20% — infrastructure automation
• 20% — prototyping, improvements, technical initiatives
