Senior Staff Engineer, Mobile Remote US, Toronto, San Francisco, Mountain View, Vancouver, Portland

Company: Mozilla

Why join Mozilla engineering?

Learn: Code review at Mozilla includes pushing to passionate contributors around the world. Building Firefox and its family of products requires knowledge up and down the stack, and extremely high standards for security and optimization. Beyond the browser, we’re developing AR/VR, IoT, and voice recognition products that respect and protect privacy.

Grow: We’re dedicated to helping every team member develop. We give engineers trust and responsibility from day one, offer generous stipends for learning opportunities, and provide mentorship, especially around key leadership skills like collaboration and clear, kind communication.

Make Your Mark: We’re small but mighty, challenging the biggest behemoths on the internet with a staff the size of their marketing departments. That means every engineer can have an outsized impact on products that touch tens of millions of users—ultimately influencing how the entire internet works.


The Role

We are looking for an industry leader to join our mobile engineering team in building Firefox products. You will have the opportunity to make company-level impact through technical leadership on Firefox projects, as well as by influencing the direction of mobile by shaping cross-team technical ownership and cooperation. Join our group of talented, passionate, kind teammates in designing and building the best experiences for the mobile web.

Mozilla Mobile Engineering is a group of highly collaborative small teams that build Firefox products on Android. You will have the opportunity to work across these teams: to help the GeckoView team embed our modern Quantum browser engine, the Android Components team build the reusable blocks of browser experience functionality, and to help compose mobile experiences users love out of all these parts as a member of the browser-building team. You will help our tech stack continue growth to support top level organizational goals.

As a Senior Staff Android Application Engineer here at Mozilla, you will...

  • Exemplify professionalism in engineering stability, maintainability, and performance.
  • Identify and drive work in areas that need attention.
  • Partner with existing technical leadership to drive constant improvements in engineering processes and strategy.
  • Actively reach out and collaborate with other teams to keep constant forward momentum.
  • Be a connector between senior leadership and mobile engineering.
  • Manage risk associated with the Mobile group’s work.
  • Mentor, sponsor, and encourage coworkers.

Your Professional Profile

  • Your technical leadership has been instrumental to shipping successful mobile projects.
  • 8+ years of experience demonstrating technical leadership, including mentoring software developers on mobile devices.
  • Strong interpersonal skills, with excellent communication in English.
  • Experience with architecture, testability, and refactoring large complex systems.
  • Experience leading work across multiple engineering teams, or work that has interdependencies with other teams.
  • Experience working with a geographically distributed team is a plus.


Join us and become part of our mission to promote openness, innovation, and opportunity on mobile. This role is available in our offices (Toronto preferred), and remote US/Canada.


Feel good about your work again.
