Project description:

The project focuses on defence and security-related systems developed and maintained in regulated and classified environments. You will work on highly secure, on-premise infrastructures with limited or no external connectivity, supporting critical software delivery pipelines and environments that must meet strict security and compliance standards. Close cooperation with infrastructure, security and project teams is a key part of the role.

Main responsibilities:

• Design, develop and maintain CI/CD pipelines for defence and security projects

• Administer and support Linux-based systems in restricted and on-premise environments

• Ensure availability, stability and security of development, test and production systems

• Automate infrastructure and operational processes to improve reliability and repeatability

• Support development teams with build, deployment and runtime issues

• Participate in incident analysis, troubleshooting and root cause analysis

• Prepare systems and documentation for security audits and compliance reviews

• Cooperate closely with infrastructure, security and project teams in classified environments
