More about the role & team

• Direct ownership of vulnerability remediation, with clear impact on reducing backlog and improving security outcomes

• Hands-on role combining infrastructure and security, rather than a purely advisory or monitoring position
• Broad exposure across enterprise systems, security tools, and cross-functional teams
• Ability to influence how security is implemented and improved at scale, not just maintain existing processes
