We are looking for a talented Unix Administrator to join our team for a multinational leader in the banking sector located in Madrid.

This role is responsible for the administration of Unix‑based servers, primarily RHEL, Ubuntu and Debian. Our environment spans a large, hybrid infrastructure of physical and virtual servers that supports mission‑critical applications and continuous production workloads.

-
- Ensure production stability – monitor,



tune and troubleshoot the server park so that all services meet their SLA deadlines and remain available for end‑user operations.
- Drive process‑automation – design, script and implement automated workflows (e.g., provisioning, configuration management, patching, and compliance checks) that reduce manual effort, accelerate delivery, and improve repeatability across the whole fleet.
- Maintain high‑availability architectures – deploy, configure and support HA solutions (clustering, load‑balancing, fail‑over) to guarantee uninterrupted production services.
- Security & compliance – perform hardening, vulnerability remediation, and patch management in a timely, deadline‑oriented manner, ensuring that security controls never become a bottleneck for production.
- Adaptability & continuous learning – stay current with emerging tools (Ansible, Python, CI/CD, etc.) and be ready to pivot when production requirements evolve or new technologies are introduced.
