Position Summary:

The Senior Manager, Cyber Security Operations is a hands-on leader responsible for building, operating, and continuously improving Ardelyx's security operations capabilities.

The right candidate thrives in build environments, is energized by consolidating a fragmented security stack onto a modern Microsoft-centric platform, and can operate effectively both as an individual contributor and as a team leader. This role provides operational direction for security operations while ensuring the confidentiality, integrity, and availability of corporate systems, data, and cloud environments.
