DevOps / Ops / Application Supporter

About the Position

We are looking for a hands-on DevOps & Application Support Engineer to join our international platform engineering team in Vienna, Austria. In this role, you will sit at the intersection of cloud infrastructure, Java application operations, and observability - helping us keep our distributed systems reliable, performant, and continuously improving. You will own incidents end-to-end, drive root cause analyses, support cloud migrations, and collaborate closely with development teams to bridge the gap between code and production.

Responsibilities

Incident Management & Root Cause Analysis

• Lead incident triage and perform structured root cause analysis on production issues across cloud and on-premise environments.
• Use monitoring and logging tools (Kibana, CloudWatch, Prometheus, Grafana) to diagnose failures and surface actionable insights.
• Define and drive post-incident reviews, ensuring findings translate into preventive improvements.

Infrastructure & Operations Support

• Support and maintain cloud (AWS) and on-premise infrastructure, ensuring high availability and operational stability.
• Manage and troubleshoot containerized workloads running on Kubernetes and Docker.
• Support deployment pipelines and release processes, coordinating with development teams to ensure smooth rollouts.

Observability & Performance

• Maintain and enhance monitoring dashboards and alerting rules across Prometheus, Grafana, Kibana, and Amazon CloudWatch.
• Identify performance bottlenecks and support optimization efforts across Java application servers and messaging infrastructure (IBM MQ, Kafka).

Cloud Migration & Infrastructure Improvements

• Actively contribute to cloud migration initiatives, helping transition on-premise workloads to AWS.
• Support Infrastructure-as-Code (IaC) practices, helping to automate and codify infrastructure provisioning.

Documentation & Service Desk

• Maintain clear, up-to-date operational runbooks, architecture docs, and incident playbooks.
• Provide second-line support to the Service Desk, acting as a knowledge bridge between operations and engineering.

Requirements

• Proven background in DevOps, Operations, or Application Support in a production environment.
• Hands-on experience with Java application development and/or Java-based application server operations.
• Solid working knowledge of AWS services and cloud-native operations.
• Proficiency with container orchestration using Kubernetes and Docker.
• Strong Linux administration and command-line troubleshooting skills.
• Practical experience with monitoring and logging tooling (e.g. Kibana, CloudWatch, Prometheus, Grafana).
• Good understanding of REST APIs, relational and NoSQL databases, and distributed systems architecture.
• Fluent English communication skills; comfortable working across a globally distributed team.

Nice to Have

• Experience with messaging systems such as Apache Kafka or IBM MQ.
• Familiarity with Infrastructure-as-Code tools (Terraform, Ansible, or similar).
• Background in Java performance tuning or JVM diagnostics.
• Experience working within ITIL or similar incident management frameworks.

We Offer

• Work on a modern, cloud-native platform with real ownership over reliability and infrastructure.
• Collaborate with a diverse, international engineering team across multiple time zones.
• Grow your skills across cloud, observability, Java operations, and platform engineering.
• Flat structure with direct impact - your work ships to production and matters immediately.
