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

Videos are a huge part of online life. Would you like to make them better? Are you interested in streaming movies and music?

Are you passionate about the open web? Do you want to build a better world? We'd love to hear from you.

The media playback team supports everything around audio and video in Firefox on Android, Windows, macOS, and Linux desktops, so we welcome broad experience across different platforms. The media team is implementing standards like MSE, WebRTC, WebAudio and integrate new codecs like AV1 into Firefox. We are particularly looking for someone who knows Android well.

  • Participate in regular code reviews.

You should:

  • Be proficient in C++ or Rust.
  • Understand Android video playback APIs.
  • Have strong debugging and optimization skills in a multi-threaded code.
  • Have at least five years of experience as a software engineer.

It helps if you already have experience with, or are keen to learn about:

  • Implementing web standards.
  • Native process separation on Android.
  • Graphics programming.
  • Helping and mentoring junior team members.
  • Working in a diverse community spanning many regions and timezones.
  • Open source collaboration tools.

Feel good about your work again.

At Mozilla, we’re serving humanity—by maintaining a safe, open internet—while also helping the individual humans employed here to reach their personal and professional goals.
