Staff Security GRC Engineer

Why Mozilla?

Mozilla Corporation is the non-profit-backed technology company that has shaped the internet for the better over the last 25 years. We make pioneering brands like Firefox, the privacy-minded web browser. Now, with more than 225 million people around the world using our products each month, we're shaping the next 25 years of technology and helping to reclaim an internet built for people, not companies. Our work focuses on diverse areas including AI, social media, security and more. And we're doing this while never losing our focus on our core mission – to make the internet better for people.

The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation. This means we aren't beholden to any shareholders — only to our mission. Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms.

About this team and role:

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.

• 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.

• 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.

• Welcoming differences
• Being relationship-minded
• Practicing responsible participation
• Having grit

• Generous performance-based bonus plans to all eligible employees—we share in our success as one team.
• Rich medical, dental, and vision coverage.
• Generous retirement contributions with 100% immediate vesting (regardless of whether you contribute).
• Quarterly all-company wellness days where everyone takes a pause together.
• Country-specific holidays plus a day off for your birthday.
• One-time home office stipend.
• Annual professional development budget.
• Quarterly well-being stipend.
• Considerable paid parental leave.
• Employee referral bonus program.
• Other benefits (life/AD&D, disability, EAP, etc.—varies by country).
