The role is expected to provide engineering ownership, operational oversight, and continuous improvement across the following cybersecurity domains:
- Security platforms and security operations technologies
- Vulnerability management, exposure management, and attack surface reduction
- Security telemetry, visibility, observability, and data quality
- Security integrations, automation, orchestration, and API-enabled workflows
- Security monitoring, analytics, detection engineering support, reporting platforms, and telemetry management.
- Security service edge and related cloud-delivered security technologies

• Lead technical planning and delivery across PAM, DLP, MDM, Secure Email Gateway, SSE, Vulnerability and Exposure management, security monitoring, automation and MDR/MSOC integration.
• Convert roadmap outcomes into requirements, designs, implementation plans, acceptance criteria, runbooks, metrics and operational handover.
• Prioritize work with the Cybersecurity Operations Head based on business risk, implementation readiness, dependencies and available capacity.
• Provide technical guidance and mentoring to the Cybersecurity Analyst and coordinate delivery partners, while remaining an individual contributor without formal people-management responsibility.
• Own administration, lifecycle management, integration, health monitoring and optimization of assigned cybersecurity platforms.
• Lead security log-source onboarding, telemetry validation and data-quality controls across cloud, endpoint, network, identity, email, application and infrastructure sources.
• Develop or oversee API, scripting, orchestration and workflow automation that reduces manual effort and improves response consistency.
• Maintain platform access governance, support procedures, technical standards, configuration baselines and service documentation.
• Lead PAM implementation and continuous improvement, including account discovery, vaulting, credential rotation, MFA, session controls, monitoring, JIT access and controlled vendor access.
• Partner with Infrastructure and application owners on onboarding privileged accounts, systems and legacy access use cases.
