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 for someone who can combine deep technical architecture capability with the ability to work across IT, Product, Cloud, Data, Legal, and Governance stakeholders. You will shape the company’s 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.
What you will do
Security architecture leadership
- Own the company’s reference security architectureand target-state security patterns across enterprise IT, infrastructure, cloud, data, and product environments
- Define architecture principles and implementation patterns for Zero Trust, identity, authorization, trust boundaries, segmentation, secure integration, and secure access
- Set the strategic direction for enterprise, cloud, and data security architecture
Cloud, IAM, and Zero Trust design
- Define target-state architecture for Enterprise IT, Cloud, and Infrastructure, including:
- IAM and identity trust models
- reverse proxy and secure access architecture
- network and data segmentation
- cloud-native control patterns
- Lead the development of architecture standards for secure integration between IT and product environments
- Partner closely with Global IT Security Engineeringon IAM, endpoint, VPN, reverse proxy, and access-tool integration
AI/ML and data security architecture
- Define security architecture for AI/ML workflows, cloud-native data platforms, and ML pipelines
- Establish and maintain AI/ML trust-boundary models
- Support architecture and product teams on secure AI adoption
- Shape standards for:
- data governance and access design
- ML pipeline trust boundaries
- model and data protection patterns
- secure use of AI assistants and AI-enabled workflows
Architecture governance and design assurance
- Lead architecture review governancefor high-risk initiatives
- Facilitate and strengthen threat modelingand secure design review practices
- Ensure that security principles are translated into reusable, practical design patterns

Stakeholder leadership
- Translate between technical architecture languageand governance / compliance / business language
- Work closely with:
- Trust & Security teams
- IT Platform and IT Security Engineering
- Product and engineering leadership
- Legal and GRC
- Coach and influence architects and technical leaders across IT, Cloud, Product, and ML environments
- Subject Matter Expert and role model in developing a Security Architecture Platform
Typical deliverables

- Architecture review records and decision logs
- Threat models for high-risk systems and initiatives
- Zero Trust design patterns
- IAM and trust-boundary architecture models
- Data and AI trust-boundary models
- Data-access design standards
- Secure implementation patterns aligned with architecture standards
What we are looking for
Essential experience
- 5+ yearsin enterprise and cloud security architecture
- 5+ yearsin identity, access, and network trust design
- 3+ yearsfacilitating threat modeling and secure design reviews
- Strong experience defining architecture standards and translating principles into practical patterns
- Experience working across enterprise IT, cloud platforms, infrastructure, and product environments
- Experience engaging with senior stakeholders across technical and non-technical functions
Essential skills

- Ability to interface effectively with DevOps, MLOps, Infrastructure, and Product Engineeringteams
Expected competence
Security architecture: Expert
Zero Trust / IAM design: Expert
Threat modeling: Advanced
Stakeholder leadership: Advanced
How you work
You are likely to be someone who:
- thinks in systems, not just controls
- can balance strategic design with pragmatic delivery
- is comfortable influencing without always owning implementation
- can create clarity in complex multi-stakeholder environments
- can make architecture standards usable by engineers, not just readable by auditors
Training and skill development
We support continued development in this role through:
- SABSA / CCSP-stylelearning paths or equivalent enterprise architecture development
- regular updates on NIST Zero Trustand 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
- cloud-native infrastructure
- sensitive data protection
- regulatory and audit readiness
- Zero Trust transformation
You will help define how security architecture enables the company to scale in a way that is trusted, resilient, and practical.
