The opportunity

The Security Architect will design and review secure enterprise technology solutions spanning IT and OT.

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

Assess architecture risks arising from legacy technologies, vendor dependencies, constrained patching, high-availability requirements and complex enterprise or industrial environments.

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.
