You will be involved in supporting systems operating in highly regulated and security-sensitive environments, where strong operational discipline, documentation, and adherence to change processes are essential. This role is well-suited for engineers who enjoy hands-on operations work, problem solving, and maintaining the stability of complex systems in production.

• Understanding of network fundamentals (TCP/IP, TLS, firewalls, proxies)
• Exposure to log forwarding / SIEM integration (e.g. Splunk, NXLog)
• Knowledge of security hardening benchmarks (e.g. CIS)
