Our client is a integral technology organization for whom protecting critical data platforms is core to the business. They're hiring a hands-on Senior Data Security Architect to take ownership of the security and compliance posture across their cloud database estate, spanning Oracle on OCI and PostgreSQL environments.
This is a role for someone who can set technical direction and get into the details - defining the security roadmap for business-critical data infrastructure at enterprise scale, in a regulated, international setting. You'll lead a dedicated security squad while working closely with platform architects, operations, and governance stakeholders across the business.
It's a great fit if you enjoy building secure-by-design infrastructure, turning regulatory requirements into practical engineering controls, and coaching engineers while staying technically active yourself.
