[Hiring] Senior Security GRC Engineer @Mozilla

Role Description

This role is part of the Governance, Risk & Compliance (GRC) function within Mozilla's Security team. The Security team supports Product, Enterprise, and GRC functions across the organization, aligned with the mission to build a safe and secure internet. This role is responsible for maintaining and advancing Mozilla's Information Security Management System (ISMS) and supporting our ISO 27001 and SOC 2 Type 2 compliance programs — from policy and control design through audit readiness and certification.

The ideal candidate has hands-on experience across the full breadth of a compliance program, is comfortable building process where none yet exists, and works well with a wide range of cross-functional stakeholders.

What you'll do:

• Maintain and mature the ISMS, including the Statement of Applicability (SoA), risk treatment plans, and the Management Review Meeting (MRM) process and cadence.
• Support ISO 27001 and SOC 2 Type 2 audit execution—helping determine scope, preparing evidence and narrative artifacts, participating in auditor interviews and walkthroughs, and resolving auditor findings.
• Contribute to the SOC 2 System Description and other audit-specific narrative documentation, ensuring they accurately reflect the organization's actual control environment.
• Track gaps and remediation efforts arising from readiness assessments and audits.
• Lead the policy program—driving policy creation, revision, and cross-functional review cycles to keep the security policy set current, enforceable, and audit-ready.
• Support compliance scaling as additional products or business units pursue readiness assessments and certification.
• Support the internal audit function, partnering with internal or third-party resources as needed to meet ISO 27001's internal audit requirements.
• Partner closely with Engineering, IT, Legal, Privacy, People teams, and product leadership to gather evidence, drive control ownership, and translate compliance requirements into practical, adoptable practices.
• Advise the GRC manager and broader Security leadership on audit risk, certification readiness, and compliance program strategy.

Qualifications

• 5 years of experience in information security, GRC, or compliance-focused roles.
• Deep familiarity with ISO 27001 and SOC 2 Trust Services Criteria, gained through meaningful involvement in audits from readiness through certification.
• Comfort operating across the full breadth of an ISMS—SoA maintenance, Management Review Meetings, and System Description authorship.
• Demonstrated experience writing and revising security policies, including running cross-functional review cycles to gain organization-wide buy-in and adoption.
• Experience tracking gaps and remediation plans and connecting that work to an organization's broader compliance and risk program.
• Excellent cross-functional collaboration skills—comfortable working with engineers, product managers, legal, and executive stakeholders, and able to translate compliance requirements into practical, actionable workflows.
• Ability to ramp up quickly and operate with a high degree of independence.
• Comfort building processes where none yet exist.
• Strong written and verbal communication skills; ability to represent Mozilla credibly and confidently in front of external auditors.
• Relevant industry certifications (e.g., CISA, CISSP, ISO 27001 Lead Auditor/Implementer) are a plus.
