Our department’s vision is to build a Data-Driven IONOS Group. Our mission is to connect AI and BI, evolve our platforms, and empower our customers. As the central provider of the BI platform for Corporate, CTO topics, and state-of-the‑art AI solutions, we support data‑driven decision‑making all across the IONOS Group.
Currently, we are building our new cloud Big Data platform completely based on the IONOS cloud infrastructure. This means you will work with up-to-date, non-commercial technologies and have the unique opportunity to operate on our own internal cloud ecosystem, completely independent of the usual hyperscalers (AWS/GCP).
As a Senior DevOps Engineer, You Won't Just Manage Namespaces Or Isolated Applications; Actively help shape, deploy, and maintain our cloud Big Data platform infrastructure, taking full responsibility for the operation of our technical data processes.
L2/L3 Application Support: Serve as the first point of contact for internal data engineering teams. You will troubleshoot process failures, investigate why a data pipeline failed, and optimize platform performance.
Agile Collaboration: Participate actively in team processes, working within 2-week sprints where the functional team develops a common goal, working independently while keeping the team aligned .
We are looking for a "Plug n' Play" Senior Engineer—someone who brings high technical expertise combined with the mindset of a curious explorer and a strong problem-solving attitude.
Experience: Minimum 5+ years of proven experience in Operations, System Administration, or infrastructure-focused DevOps roles.
Confident, high-level handling of Linux systems, environments, and server recovery processes.
CI/CD & IaC:



Deep practical experience with infrastructure-as-code and deployment automation technologies, specifically ArgoCD and Terraform.
Strong knowledge and hands‑on experience with Kubernetes and containerization technologies.
Open Source Stack: Familiarity or practical experience with tools such as Trino, Hive, Airflow, OpenShift, Prometheus, or Grafana is highly valued.
Networking: Practical experience with networking concepts and technologies.
Communication: Good English skills (written and spoken) to collaborate effectively across multidisciplinary and international teams.
Practical experience with Python programming and related frameworks.
Linux Foundation certifications regarding Kubernetes (e.g., handling sensitive data or regulated sectors).
Profiles with a pure Software Engineering focus (e.g., long-time software developers whose DevOps experience is limited to writing automation scripts for a dev team). Candidates with exclusive, closed experience in AWS only. We value the flexibility to understand alternative cloud-native architectures.
Fixed salary and flexible benefits such as health insurance, daycare allowance, and meal vouchers.
Versátil working hours to organize your schedule according to your needs.
Ability to work hybrid in any of our offices located in Logroño, Madrid, Barcelona, Seville, Valencia, or Bilbao.
Personalized training in cutting-edge technologies, certifications, or any area that interests you.
At Arsys we value diversity and welcome all applications regardless of, for example, gender, nationality, ethnic or social origin, religion, disability, age, as well as sexual orientation and identity, physical characteristics, marital status or any other irrelevant factor subject to applicable law.
