      • System design and architecture patterns

      • Data modelling and entity relationship design

      • API design and system integration

    • Broad IT background with the ability to engage confidently with non-security SMEs

    • Experience across both operational and transformational security environments

    • Proven delivery within large-scale IT transformation programmes

    • Ability to represent security at technical and design authorities

  • Technology & tools

    • Experience with Check Point, Illumio, Fortinet, or similar firewall technologies

    • Architecture modelling tools (BizzDesign, Archi, UML or equivalent)

    • Jira for delivery tracking and Confluence for documentation

    Technology stack

    • Python, JavaScript, Flask, FastAPI, NGINX, Databricks, PostgreSQL, Red Hat Enterprise Linux, GitHub, Jenkins, HashiCorp Vault

    Qualifications (preferred)
