Staff Security Engineer, Product Security

📋 Description

• • As a Staff Security Engineer in Product Security at Mozilla, you will protect the privacy and safety of millions of users by embedding security into Firefox, Mozilla VPN, and other mission-critical products, ensuring the internet remains a global public resource built for people, not companies.
• • Your day-to-day responsibilities include safeguarding users by integrating security into the full Software Development Life Cycle (SDLC), performing threat modeling and security assessments, conducting security code reviews, leading penetration testing on web, mobile, and embedded applications, developing automated security tests in CI/CD pipelines, and partnering with engineers to make security a core design principle rather than an afterthought.
• • You will join Mozilla Corporation, a non-profit-backed technology company wholly owned by the Mozilla Foundation, dedicated to shaping the internet for the better over 25 years through open-source products like Firefox, used by over 225 million people monthly, with a mission to reclaim an internet built for people, not companies.
• • In this role, you will deepen your expertise in application security, cloud environments (AWS, Azure, GCP), secure coding practices, and automation, while influencing cross-functional teams, shaping Mozilla’s security culture through education and guidance, and advancing your impact as a builder and protector of user privacy and safety at scale.
