Senior Manager, Cyber Security Operations

Ardelyx is a publicly traded commercial biopharmaceutical company founded with a mission to discover, develop and commercialize innovative first‑class medicines that meet significant unmet medical needs. Ardelyx has two commercial products approved in the United States, IBSRELA (tenapanor) and XPHOZAH (tenapanor). Ardelyx has agreements for the development and commercialization of tenapanor outside of the U.S. Kyowa Kirin commercializes PHOZEVEL (tenapanor) for hyperphosphatemia in Japan.

A New Drug Application for tenapanor for hyperphosphatemia has been approved in China with Fosun Pharma. Knight Therapeutics commercializes IBSRELA in Canada.

The Senior Manager, Cyber Security Operations is a hands‑on leader responsible for building, operating, and continuously improving Ardelyx's security operations capabilities. This role combines technical execution with leadership, requiring a “player‑coach” who can both lead the function and actively engage in day‑to‑day security operations - not a purely strategic role.

This is a greenfield opportunity. As Ardelyx transitions from a managed service provider (MSP) model to an internally operated IT and security organization, this individual will help build the security operations function from the ground up. 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. The ideal candidate brings deep technical expertise, operational discipline, and practical leadership, with the ability to communicate effectively with executives, auditors, engineers, and cross‑functional teams.
