• Establish controls and visibility to manage certificate lifecycle and prevent expiration-related risks
• Champion operational excellence through automation, outage reduction, and service resilience improvements
• Represent Infrastructure Security in architecture reviews, incident response, and compliance initiatives
• Mentor and develop other engineers, influencing secure engineering practices across teams
• Stay current with industry threats, trends, and mitigation techniques related to infrastructure security
