• Prepare documentation including build guides, runbooks, and security implementation plans.

People Leadership

• Provide mentoring and technical guidance to junior engineers within the team or project streams.
• Actively engage in team stand-ups, architecture reviews, and delivery retrospectives to share learnings and promote secure delivery practices.
• Work collaboratively with multidisciplinary project teams and promote shared accountability for secure outcomes.

Governance & Risk

• Review configuration changes and provide input into security policies and control baselines during build activities.
• Support audit readiness and evidence gathering for new solutions.
• Ensure all designs and implementations comply with internal policies and regulatory obligations, including privacy and data-protection requirements.
• Identify security gaps or control failures during project delivery and support timely remediation.
• The above list of key accountabilities is not an exhaustive list and may change from time-to-time based on business needs.
