Job description

Cybersecurity Assurance & Architecture Specialist (AWS)

An experienced Cybersecurity Assurance & Architecture Specialist is required to join a major technology and operations function responsible for the security, resilience and assurance of critical enterprise and operational systems.

This is a highly visible contract opportunity for a security professional who can combine hands-on AWS security architecture expertise with strong technical assurance and cyber resilience experience. You'll work closely with engineering, DevSecOps and delivery teams, helping to identify risks, improve security controls and ensure solutions are delivered securely without creating unnecessary barriers to delivery.

You'll be joining a large-scale environment undergoing continual transformation, supporting hundreds of business-critical systems across cloud, data, integration and operational technology platforms.

The Environment

You'll be working within a complex, regulated environment where cyber security, resilience and operational assurance are fundamental to successful delivery. The role sits at the intersection of architecture, assurance and engineering, requiring someone who can engage confidently with both technical and non-technical stakeholders.

This is not a purely governance or compliance position. The successful contractor will be expected to understand how security controls work in practice and collaborate directly with teams responsible for implementation.

Why Join?

• Influence the security and resilience of large-scale operational platforms
• Work across cloud, data, integration and enterprise technology programmes
• Collaborate directly with engineering, architecture and delivery teams
• Join a fast-paced environment where security is embedded throughout the development lifecycle
• Long-term contract opportunity with significant scope and visibility

Key Responsibilities

• Provide cyber security architecture guidance across AWS, SaaS and PaaS environments
• Conduct technical cyber security assurance and resilience reviewsIdentify security risks, vulnerabilities and control gaps across systems and services
• Support secure-by-design initiatives throughout the software delivery lifecycle
• Review system integrations, network security controls and access management approaches
• Validate technical security controls and assurance evidence
• Support third-party and supplier security assurance activities
• Work closely with engineering and DevSecOps teams to deliver practical remediation solutions
• Strong AWS security architecture experience
• Technical cyber security assurance experience within complex enterprise environments
• Secure-by-design and security architecture expertise
• Experience performing technical risk assessments and control reviews
• Knowledge of NIST and NCSC-aligned security frameworks
• Understanding of cloud security, network segregation, firewall controls and access management
• Experience working alongside developers, engineers and technical delivery teams
• Excellent stakeholder engagement and communication skills
• Cyber resilience and operational resilience assessment experience
• Supplier and third-party security assurance
• Experience within regulated, critical infrastructure or operational environments
• Exposure to CI/CD pipelines and DevSecOps practices

What We're Looking For

We're looking for a proactive, pragmatic and technically credible cyber security professional who enjoys solving problems and building relationships across engineering teams.

You'll be comfortable investigating issues independently, challenging where necessary and working collaboratively to deliver secure outcomes. Strong communication skills are just as important as technical capability, as you'll be engaging regularly with architects, developers, delivery teams and senior stakeholders.
