  • Write the technical documentation installation guides configuration baselines test plans and reports procedures hardening guides.
  • Advise on architecture tool configuration system integration and operational improvement.
  • Support vulnerability management and incident response including evidence collection log analysis and reporting.
  • Support handover to operations including knowledge transfer and training.

What you would bring

  • At least five years in cyber security or a comparably demanding technical field.
  • Broad knowledge of security tooling and its configuration including boundary protection firewalls intrusion prevention on network and host data diodes.
  • Encryption identity and access management monitoring and detection incident response vulnerability assessment forensics and risk management.
  • Recent hands-on work with Juniper Palo Alto web application proxies RSA NetWitness Splunk Tenable Nessus and AccessData.

  • A record of delivering systems and capabilities to government or defence customers including work deployed in the field.
  • Excellent technical writing and communication in English at professional level.
  • Working proficiency with the ArchiMate modelling language.

A degree in a related discipline with three years of post-related experience or about ten years of progressive experience instead. Implementation projects within NATO or a national military organisation are desirable.
