Senior Cloud Security Architect

Senior Cloud Security Architect

Location: Dublin (Remote-Hybrid)
Type: Full-Time
Salary: €100,000 – €130,000

A technology group is expanding its security architecture function and adding a Senior Cloud Security Architect to guide design decisions across large-scale environments. The role blends hands-on technical depth with advisory work, helping enterprise engineering teams design defensible cloud foundations, reduce misconfiguration risk, and embed automation across their delivery workflows.

You’ll collaborate across multiple technical domains: cloud, identity, network, DevOps, and platform engineering, shaping the guardrails that keep distributed environments resilient and predictable.

The Role

You will lead the design, review, and validation of cloud security architectures across Azure-centric and hybrid estates. Expect a mix of strategy, design assurance, security automation, and hands-on work with identity, policy, IaC pipelines, and monitoring stacks. This is a senior role with influence, not a box-ticking function: you’ll be expected to challenge design assumptions and help engineering teams make better decisions.

Primary Responsibilities

• Architect secure cloud environments and validate design decisions across identity, network, data, and platform layers

• Develop cloud security baselines, policy bundles, and guardrails for Azure and hybrid environments

• Review cloud architecture patterns and recommend improvements grounded in practical risk reduction

• Lead security assessments and architectural walkthroughs, producing clear and actionable technical outputs

• Design and maintain landing zone frameworks and automated deployment patterns using IaC

• Integrate security controls into CI/CD pipelines and delivery workflows

• Strengthen cloud observability: logging patterns, security signal quality, detection coverage

• Support Zero Trust adoption across identity, device, access, and segmentation models

• Provide remediation guidance and partner with engineering teams to close design gaps

• Mentor engineers, advise technical leads, and support threat-modelling sessions

• Contribute to long-term cloud security strategy and capability development

Skills & Experience

• Strong background in cloud security architecture within large-scale Azure environments

• Deep knowledge of Azure identity, policy, monitoring, and security services

• Advanced proficiency with Infrastructure-as-Code (Terraform preferred, Bicep/ARM beneficial)

• Solid understanding of cloud networking, segmentation, and trust boundary design

• Experience integrating security controls into CI/CD and automated deployment workflows

• Familiarity with Zero Trust principles applied within cloud ecosystems

• Strong knowledge of cloud security frameworks and regulatory drivers

• Ability to produce clear technical documentation and architecture guidance

• Experience collaborating with engineering, DevOps, and compliance groups

• Cloud and security certifications are beneficial but not required

Nice to Have

• Experience securing multi-cloud (AWS or GCP)

• Familiarity with CSPM, CIEM, and cloud governance tooling

• Understanding of regulated-industry requirements and audit expectations

• Exposure to OT/ICS environments or hybrid platform designs

• Broader cybersecurity accreditations (CISSP, CCSP, CISM, etc.)
