The Security Architect will design and review secure enterprise technology solutions spanning IT and OT. The role will translate regulatory, risk and compliance requirements into practical security architecture principles, control requirements and implementable solution designs. The architect will work with technical and non-technical stakeholders to challenge designs, identify security risks and support proportionate remediation decisions.

• Develop secure current-state, target-state and solution architectures for enterprise IT and operational technology environments.
• Review technology and project designs, identify security risks and recommend proportionate remediation options that balance security, safety, operational continuity, cost and delivery constraints.
• Translate regulatory, risk and compliance obligations into practical security architecture principles, patterns, technical controls and solution requirements.
• Apply relevant security architecture standards and frameworks, including IEC 62443 concepts such as zones, conduits and Security Levels, to OT architecture and control design.
• Define security controls across identity, privileged access, networks, endpoints, cloud platforms, applications, data, industrial systems, engineering workstations, servers, sensors, monitoring platforms and third-party services.

• Design and review industrial security monitoring and sensor architectures, including sensor placement, coverage, connectivity, integration and operational support requirements.

• Produce clear, implementation-ready security architecture documentation, including Security Architecture Documents, high-level and low-level designs, architecture diagrams, control matrices, risk assessments, decision records and implementation requirements.
• Work with control-system engineers, operations, infrastructure, application, cloud, security, risk, compliance and third-party stakeholders to resolve design issues and technical constraints.
• Support security design governance, architecture review boards, security assurance, testing, risk-acceptance and design-approval decisions.
