Security Architect - Tooling & Product Architecture

Location: Dublin City Centre / Hybrid

Type: Permanent

Salary: Competitive

About the Role

We're looking for a Security Architect who genuinely enjoys working with security tools and products. This is not a governance-heavy architecture role - it's for someone who gets excited about evaluating new security technologies, understanding how they work under the hood, and designing integrated security ecosystems that deliver real operational value.

You'll combine hands-on technical depth with strategic architecture thinking, working across endpoint security, identity, cloud security, SIEM, and threat detection platforms. A key requirement is extensive CrowdStrike experience.

The role focuses on architecting and optimising security tooling across the organisation, including endpoint protection, IAM/PAM, cloud security, SIEM, vulnerability management, and data protection solutions. It also involves evaluating new products through technical assessments and POCs, integrating tools across infrastructure and cloud environments, defining security standards and best practices, and collaborating with engineering, infrastructure, compliance, and incident response teams to improve visibility, detection, and operational effectiveness.
