About the role: We are looking for a Lead Security Architect to define and evolve the company’s reference security architecture across enterprise IT, cloud, data, product, and AI/ML environments. This is a senior leadership role combining deep technical architecture capability with the ability to work across IT, Product, Cloud, Data, Legal, and Governance stakeholders. You will shape the target-state architecture for Zero Trust, IAM, reverse proxy, segmentation, AI/ML trust boundaries, and secure integration patterns, while ensuring security architecture remains practical, scalable, and aligned to business priorities. You will play a central role in helping the company scale securely as an AI-first, cloud-first organisation operating in a regulated context with ISO 27001, NIS2, and sensitive data protection requirements.

How you work

You are likely to be someone who: systems-thinking, balances strategic design with pragmatic delivery, influences without always owning implementation, creates clarity in complex multi-stakeholder environments, and makes architecture standards usable by engineers, not just readable by auditors.

Training and skill development

We support continued development in this role through: SABSA / CCSP-style learning paths or equivalent enterprise architecture development; regular updates on NIST Zero Trust and cloud architecture patterns; AI system and data-governance design training; ongoing exposure to architecture, governance, and regulatory developments relevant to cloud, AI, and security.

Why join us

This role offers the opportunity to shape the security architecture of a modern company operating at the intersection of AI-first product and engineering practices, including cloud-native infrastructure, sensitive data protection, regulatory and audit readiness, and Zero Trust transformation. You will help define how security architecture enables the company to scale in a way that is trusted, resilient, and practical.

We empower individuals to celebrate their uniqueness. Our team comes from all walks of life, and we’re proud to encourage and support applicants from underrepresented groups.
