DevOps Engineer

Position Overview

Important: Travel & On-Call Requirements

This role requires readiness for long-distance international travel to customer sites. The systems are deployed globally and, when issues cannot be resolved remotely, on-site interventions may be necessary, including deployments, upgrades, and complex troubleshooting activities.

Additionally, the position includes participation in a rotational on-call / standby schedule, ensuring operational continuity and the ability to respond to critical incidents outside of standard working hours.

We are looking for an experienced DevOps Engineer to join a team responsible for the maintenance and further development of a complex automation system deployed on-premise at customer sites. The system is based on Linux (Ubuntu) and a containerized Kubernetes architecture.

The platform consists of multiple cooperating application and infrastructure components, including:

• backend services

• GPU-based computing components (CUDA)

• communication layer

• storage

• networking components

The environment is characterized by high operational complexity and strong dependencies between system layers (OS, Kubernetes, applications, networking, storage). Systems are deployed across multiple locations worldwide and often operate in environments with limited local IT support, which requires high reliability and well-defined operational procedures.

The DevOps role goes beyond reactive incident handling. A key objective of the project is to systematically reduce the need for on-site interventions by developing automated monitoring, diagnostics, and recovery mechanisms.
