Senior Security GRC Engineer

Mozilla

About The Position

This role is part of the Governance, Risk & Compliance (GRC) function within Mozilla’s Security team, which supports Product, Enterprise, and GRC functions across the organization. The position is responsible for maintaining and advancing Mozilla’s Information Security Management System (ISMS) and supporting ISO 27001 and SOC 2 Type 2 compliance programs, from policy and control design through audit readiness and certification. The successful candidate will bring hands-on experience across compliance programs, be comfortable establishing processes where none exist, and work effectively with cross-functional stakeholders. The role maintains the ISMS, including its Statement of Applicability, risk treatment plans, and Management Review Meeting process. It supports audit execution, evidence preparation, auditor interviews and walkthroughs, findings resolution, narrative documentation, gap tracking, policy development and review, compliance scaling, and internal audit requirements. The engineer partners with teams across Mozilla to gather evidence, establish control ownership, turn requirements into practical workflows, and advise GRC and Security leadership on audit risk, certification readiness, and compliance strategy.
