Firefox Staff Privacy Engineer

Are you passionate about Firefox and the open Web? Do you want to ship software to a massive user base? Do you want your contributions to have a positive impact on the world? Do you want the Web to be more private by bringing state of the art privacy features to everyone?

Mozilla exists to build the Internet as a public resource accessible to all because we believe that open and free is better than closed and restricted. We are looking for a Staff Privacy Engineer to research and develop our next generation of privacy enhancements for Firefox.


In this role, you will

  • Develop cutting edge privacy features with world class engineering and cross-functional teams to protect the privacy of millions of Firefox users.

  • Develop a good understanding of the core web technologies like the same origin policy and storage access policies.

  • Develop a good understanding of the technologies used to track users online like browser fingerprinting, cookie synchronization, and persistent tracking techniques.

  • Gain experience auditing the privacy practices of websites.

Your weekly job responsibilities

  • Develop new privacy features in Firefox and maintain existing ones by writing new code (mostly in C++ and JavaScript) and automated tests (mostly in JavaScript).

  • Attend video conference team meetings to share ongoing progress and have design and architectural discussions with other team members.

  • Coordinate the software development work with colleagues across the organization (product management, marketing, data science, and senior leadership).

  • Monitor and resolve user reports related to privacy features in Firefox.

  • Occasionally participate in design discussions focused on solving new problems (as needed).

  • Keep yourself updated with the recent developments in the field, with the help of your colleagues.
