Contribute to security awareness and knowledge-sharing initiatives across technology teams and business stakeholders.

Mentor junior team members and provide guidance on security processes, technologies, and best practices.

Participate in on-call and incident response activities as required to support business continuity and operational objectives.

How do we define success for your role?

You identify, recommend, and are focused on effective service delivery to our clients
You share in an inclusive and engaging work environment that develops, retains, and attracts talent
