About the role

St Vincent’s Health Australia has committed, through Strategy 2030, to connecting care across its public hospitals, private hospitals, aged care and virtual care services, with half of all care delivered virtually or in people’s homes by 2030.

Secure, reliable access to clinical systems, from anywhere, is foundational to that. We’re undertaking a significant uplift of our secure access capability. We’re moving away from centralised data centre internet egress and on-premises VPN and web security, and towards a cloud-delivered SASE/SSE platform built on Zero Trust principles.

As our Senior Network Security Engineer, you’ll be SVHA’s senior technical authority for Secure Service Edge. You’ll set the architecture and lead it hands-on from PoC through design, build and rollout into operations. You will:

• Lead PoCs, vendor evaluations across multiple vendor ecosystems (Cisco, Zscaler, Netskope, Palo Alto, Island).
• Lead hands-on low level design, build and enterprise rollout of web security, ZTNA, CASB, DLP and browser isolation.
• Advise D&T leadership and clinical stakeholders on Zero Trust and secure access.

• Design the integration of SSE with Cisco SD-WAN, Cisco Secure Firewall, identity and endpoint platforms, including the transition from centralised to regional and local internet breakout.
• Review and assure low-level designs, configuration artefacts and integration patterns produced by vendors and delivery teams.
• Ensure operational readiness through runbooks, policy libraries, monitoring and knowledge transfer to Cyber Operations and Infrastructure teams.
• Ensure SSE designs meet healthcare, privacy and cyber obligations, including SOCI, ISO 27001, Essential Eight and OAIC requirements.
• Provide senior escalation for complex or systemic secure access issues, and mentor engineers across cyber, cloud, identity and network teams.

Things that work for us

• 8–10+ years in senior technical roles across network security, cloud security or secure access, including 5+ years in an SSE-focused, security technical lead or cloud security architect role.
• Extensive hands‑on experience designing, implementing, operating and troubleshooting SASE/SSE capabilities across large, complex organisations, including: SWG and SSL/TLS inspectionCASB, ZTNA and DLPcloud firewall and RBI/enterprise browsers
• Demonstrated experience leading technical design, PoC, build and enterprise rollout of SASE/SSE. This includes at least one large-scale Zscaler (ZIA/ZPA) or Netskope deployment, ideally across multiple vendor ecosystems.
• Strong hands‑on Cisco Secure Firewall (FTD/FMC) experience.
• Expert routing skills (BGP, OSPF, PBR, ECMP, IPsec/GRE tunnel design), including integrating Cisco SD-WAN with cloud-delivered security.
• Advanced, structured troubleshooting across the full SASE traffic path, from endpoint and identity through SD-WAN, firewall and SSE tunnels to cloud policy.
• Deep understanding of Zero Trust, identity federation (Entra ID, SAML, SCIM) and agentless access for clinical, IoT and OT devices.
• Proven ability to produce high-quality designs, standards and cost models, and to secure endorsement from architecture forums and cyber leadership.
• Exceptional stakeholder engagement across executive, clinical and technical audiences, ideally in healthcare, critical infrastructure or the public sector.
