Requirements Business Enablement

• Deliver cyber engineering services that protect business operations and align with risk appetite, safety requirements, and regulatory obligations.
• Partner with Operations, IT, Networks, Projects, and Engineering to ensure controls are practical, sustainable, and enable reliable system performance.
• Translate regulatory, CI Act, and AESCSF requirements into actionable engineering activities.
• Provide expert, influential advice on complex security issues, including OT/IT convergence, vendor access, remote support, and safety-critical industrial environments.

Cyber Security Engineering

• Design, implement, and support security controls across IT, OT, AI and IoT systems.
• Deploy and manage technologies such as firewalls, SASE/SSE, EDR/XDR, SIEM/SOAR, IAM, encryption, and industrial security platforms.
• Implement secure network segmentation across OT environments, including DMZs, Zone/Conduit models, and vendor remote access models.
• Embed DevSecOps practices into CI/CD pipelines, including SCA, SAST/DAST, secrets management, and build pipeline hardening.
• Use automation (IaC, policy-as-code, configuration compliance tools) to maintain secure baselines.
• Oversee delivery of secure engineering outcomes for projects, maintenance activities, and system upgrades.
• Perform risk assessments, threat modelling, vulnerability analysis, and configuration compliance reviews.
• Support uplift of AESCSF maturity and compliance with ISA/IEC 62443, NIST CSF, ASD Essential 8, and CI Act obligations.
• Identify control gaps and work with Technology and Engineering teams to implement mitigations.
• Maintain documentation, standards, patterns, and OT system security baselines.
