We give you a world of potential

Technology underpins everything we do. We are looking for an experienced and influential engineering leader to define and deliver the global strategy for our core infrastructure services, identity platforms and network security controls.

This is a senior strategic role with the opportunity to shape CTO direction across identity, network security and zero trust. Connecting enterprise architecture, information security, service operations and business-aligned technology teams, turning business and regulatory requirements into secure, resilient and consistently engineered global services.

A role you will love 

As Head of Core Services Engineering, you will lead the engineering and lifecycle management of tier-0 services that are fundamental to the security, resilience and operation of our organisation. These include DNS, DHCP, IP address management, network time, secure access, identity and access management, privileged access, identity governance, PKI, cryptography, load balancing, network surveillance and monitoring.

Other key responsibilities:

• Define and lead the global strategy, standards and multi-year roadmap for core services and network security, aligned with CTO, CISO and enterprise architecture direction.
• Act as a design authority for core services, establishing reference architectures, approved patterns, engineering standards and reusable frameworks.
• Own budgets, investment cases, licences, renewals, hardware lifecycle, support contracts and strategic vendor relationships.
• Lead audit, control testing, disaster recovery and remediation activity across identity, access and core network controls.
• Build, lead and develop distributed engineering teams across EMEA, North America and Australia, creating a culture of automation, accountability, reliability and continuous improvement.

What will you bring to the role? 

You will have extensive experience leading identity or core infrastructure services in a large, regulated and geographically distributed organisation. You will be comfortable setting strategic direction while retaining the technical credibility to facilitate architecture discussions, challenge designs and make decisions affecting critical global services.

Other key skills required for the role include:

Essential

• Deep knowledge of core infrastructure services, including DNS, DHCP, IPAM, DDI platforms and resilient network-time architectures.
• Strong experience of secure access and web security technologies, including SASE/SSE, Zscaler, proxy, WAF, load balancing and application delivery. 
• Architecture-level understanding of Active Directory, Microsoft Entra ID, hybrid identity, conditional access, federation and modern authentication protocols.
• Experience with privileged access management and identity governance platforms, ideally including CyberArk and SailPoint.
• Knowledge of zero trust architecture, MFA, FIDO2/passkeys, certificate-based authentication, device trust and risk-based access controls.
• Strong understanding of PKI, HSMs, certificate lifecycle automation, cryptographic standards and emerging post-quantum requirements.
• Experience integrating monitoring and observability platforms with SIEM, IT service management and configuration-management capabilities.
• Experience of agile delivery, product roadmaps, prioritised backlogs and service-management practices.
• Commercial expertise covering financial modelling, TCO analysis, vendor management, contract negotiation and SLA management.
• Excellent communication and influencing skills, with the ability to translate complex infrastructure, security and resilience topics into business value for executive, risk and technical audiences.

Desirable

Relevant professional certifications would be advantageous, including:

• CISSP, CISM, CCSP or equivalent security qualifications
• CyberArk, SailPoint or Ping Identity certification
• Zscaler, Cisco, F5 or Infoblox certification

Your decisions will directly influence our organisation’s security posture, operational resilience and regulatory standing.
