Cyber Security Specialist

Cyber Security Architecture & Assurance Lead

Location: Dublin / Hybrid - onsite 3 days a week (non-negotiable)

Engagement: 6 month rolling day rate Contract

Focus: Cyber Recovery | Architecture | Operational Resilience

We’re supporting a large, complex organisation on a significant Cyber Recovery Technology Programme and are looking for an experienced Cyber Security Architecture & Assurance Lead to take technical ownership of the architecture and assurance agenda.

This is a senior, hands-on architecture role. You’ll act as a trusted technical advisor, defining and governing the target cyber recovery architecture while providing independent challenge across technology teams, programme stakeholders and third-party suppliers.

The role

You’ll be responsible for:

• Leading the technical architecture for a major Cyber Recovery programme
• Defining and governing the Target Cyber Recovery Architecture
• Setting architecture principles, standards, reference architectures and design patterns
• Reviewing and challenging technical designs and supplier proposals
• Identifying architectural risk, dependencies, technical debt and single points of failure
• Ensuring multiple technologies, workstreams and suppliers come together as one cohesive recovery capability
• Providing architecture leadership across recovery infrastructure, immutable backups, cyber recovery vaults and clean-room environments
• Supporting cyber recovery testing, simulations and readiness reviews
• Ensuring solutions align with agreed RTOs and RPOs

What we’re looking for

You’ll ideally bring strong experience across Enterprise, Solution, Infrastructure or Cyber Recovery Architecture, with demonstrable experience designing or governing Cyber Recovery, Disaster Recovery or Operational Resilience programmes.

Technically, we’re particularly interested in experience across IAM / Active Directory / MFA / PAM, VMware, enterprise infrastructure and storage, SQL Server and Oracle RAC, alongside immutable backup, cyber recovery vault and air-gapped recovery solutions.

Experience with Azure, Microsoft 365, Kubernetes/OpenShift and hybrid cloud recovery would be beneficial. Backgrounds in critical infrastructure, transport, aviation, utilities, financial services or other NIS2-regulated environments are particularly relevant.

This should suit someone who can operate at a senior architecture level but is still comfortable getting into the detail, challenging assumptions and working across complex technical environments.
