- Security & Resilience at the Core – Embed cyber resilience and regulatory compliance into IIoT design, supporting Critical National Infrastructure requirements.
- Thought Leadership – Influence Cadent’s Industry 4.0 and OT digitalisation journey, evaluating emerging technologies and setting future direction.
- Collaboration & Mentorship – Work closely with enterprise, domain and solution architects, while mentoring teams and building architectural capability.
