Job description

Do you want to work in a diverse and international company where we build future ICT solutions together?

At CSC, we offer unparalleled growth opportunities, a supportive and inclusive environment, and the chance to work on the future of research and learning. Join us today!

We are seeking a cool-headed and self-motivated Linux System Administrator to join our team and help maintain, develop, and support our Linux-based infrastructure for services for sensitive data management. This role is suited for someone with hands‑on experience managing production environments and who is comfortable troubleshooting issues independently.

Our group provides sensitive data management services, for example on human genomes and health data consented for research purpose. We work closely with Finnish biobanks, research institutes and other national stakeholders to provide the necessary capacity to process, analyse, store and share data in a secure manner. The following links will provide more background information relevant for the position:

Key Responsibilities:

Your main responsibilities are in day-to-day administration of Linux servers and services in production environments, monitoring system health, performance and capacity, and troubleshooting operating system, application, and network related issues. You will manage users, permissions, storage, and system updates, participate in incident resolution and root cause analysis, and automate routine operational tasks. Working closely with development and infrastructure teams and maintaining technical documentation and operational procedures are at the core of your work.

What we expect:

We require solid experience administering Linux systems and strong troubleshooting and problem-solving skills. A good understanding of TCP/IP networking, DNS, routing, and firewall concepts is required, as well as experience with shell scripting (Bash) and a willingness to automate repetitive work. Understanding of system security, patch management, and access control is a necessity, and familiarity with virtualization platforms and infrastructure—e.g. kernel virtual machines and Kubernetes—operations are also expected. In addition, we're also asking for experience with monitoring, logging, and performance analysis tools, and that you can work independently and communicate clearly with technical and non-technical stakeholders.

What we offer

At CSC, our employees enjoy a wide range of benefits designed to support both their professional and personal lives. We offer flexible working hours and the option for remote work, making it easier to balance work and daily life. Our comfortable workspaces in Keilaniemi, Espoo, and Renforsin Ranta, Kajaani, are designed to facilitate both teamwork and tasks that require quiet concentration. We provide comprehensive occupational healthcare services, comprehensive health insurance, and remote work insurance. Employees can take advantage of a lunch benefit during the workday, and we support recreational activities with sports and cultural benefits.

The selected candidate will be subject to drug screening and basic security clearance. The requirement for the employment relationship is that the security clearance does not reveal any noteworthy factors.

Diversity is part of who we are, and we continuously work to ensure the diversity and equality of our workplace. We encourage all skilled applicants regardless of background to apply for the position.
