Cybersecurity Architect - Threat and Vulnerability Management

The Cybersecurity Architect will join the Purple Team, responsible for designing, validating, and continuously evolving enterprise security architecture in alignment with real-world adversarial threats. This role operates at the intersection of offensive and defensive security, leveraging Red Team insights and Blue Team capabilities to ensure systems are secure by design, resilient by default, and continuously tested against emerging attack techniques. As a key leader in the security organisation, the Cybersecurity Architect will drive secure design principles, reference architectures, and security standards across a modern, SaaS-enabled and cloud-first ecosystem, including complex identity flows, third-party integrations, APIs, and distributed systems.

The role requires balancing technical depth and strategic influence, translating complex threats into actionable architectural improvements and guiding the organisation toward Zero Trust and secure-by-design maturity. Success is measured by the organisation's ability to prevent, detect, and respond to sophisticated threats, and by the strength and scalability of its security architecture across enterprise and SaaS environments.

• Design and evolve enterprise security architecture with a strong emphasis on secure-by-design principles, ensuring security is embedded early in system and application life cycles.
• Lead the development and adoption of secure design patterns and reference architectures, particularly for cloud-native and SaaS-based environments.
• Act as a key liaison between Red Team and Blue Team, translating adversarial findings into architectural improvements, detection use cases, and resilient system designs.
• Plan and execute Purple Team exercises to validate security controls across infrastructure, applications, and SaaS platforms, ensuring visibility and response capabilities are effective.
• Develop and maintain threat models for critical systems, including SaaS integrations, APIs, and identity flows, identifying attack paths and prioritising mitigations.
• Define and enforce security architecture standards for SaaS adoption, and assess and secure SaaS ecosystems including third-party integrations, OAuth applications, and API exposure risks.
• Evaluate and recommend controls for modern architectures, including Zero Trust, microservices, containers, and serverless environments, and drive improvements in detection engineering by mapping adversary TTPs (e.g., via MITRE ATT&CK) to logging, alerting, and response capabilities.
• Collaborate with cloud and platform teams to ensure secure configuration and continuous compliance across SaaS and IaaS environments.
• Conduct architecture risk assessments and provide actionable remediation strategies aligned with business risk tolerance, and promote security observability across SaaS platforms through proper logging, telemetry, and SIEM/SOAR integration.
• Mentor engineers and architects on secure design principles, SaaS security risks, and adversarial thinking.

• Bachelor's degree in Cybersecurity, Computer Science, or related experience.
• 7+ years of experience in cybersecurity, with at least 2–3 years in architecture or senior engineering roles.
• Hands‑on experience in Cyber Threat and Offensive Security operations to test and validate the effective operation of security controls, measuring the ability to stop threats and attacks at the earliest point in the kill chain.
• Strong knowledge of network security, cloud security (AWS/Azure/GCP), and enterprise architectures.
• Strong understanding of the fundamental operations of servers, operating systems, networks, cloud applications and infrastructure, along with an advanced understanding of the…
