Apply for this job
Mountain View, Portland, San Francisco

Mozilla is hiring Software Engineering Interns into our technical teams throughout the world. Our headquarters are based in the Bay Area, but we also have opportunities at our offices in Portland, Vancouver, Toronto, London, Paris, and Berlin!

We are engineers, designers, makers, and problem solvers. We work in the fishbowl known as the open source community, with a clear focus on making the Web better. Working with us, you’ll help build interesting new features and improvements in Firefox. To be part of the team, we ask that you be technically-curious, a capable and always-interested-in-learning-more programmer, and excited to be moving the Mozilla mission forward.

Mozilla isn’t just a great place to work, it’s an experience you’ll carry with you throughout your career. As part of our internship program, you’ll have the opportunity to be mentored one-on-one by a talented and experienced developer, to impact the projects you’ll collaborate on, and to never be bored. Ever. From the passionate people you’ll learn from, to the chances you’ll have to make the Web a better place, your time with Mozilla will be unlike any other.

Below is a small snapshot of the work we do to give you an idea about some of the big things you could do at Mozilla.

We are hiring 3 interns to work out of Mountain View, CA and Portland, OR

Desktop Firefox Engineering Intern (Mountain View, CA)

The Desktop Firefox team handles the engineering for much of what makes the browser a great application for users, and more than just a rendering engine. You’ll have the opportunity to work on many facets of Firefox, from creating a refined UI that balances power and simplicity to components that store user data and integrate with online services. Expand your programming skills across multiple domains — Firefox uses cutting-edge JavaScript and CSS for its UI, C/C++ in the core, and platform-specific toolkits too. Be part of a small team with a large reach, where individuals can have a major impact.


Test Pilot Internship (Portland, OR)

The Test Pilot team is seeking someone to join a small, enthusiastic team focused around rapidly testing new features in Firefox. The team's process is built around getting feedback frequently and directly from an active user base which allows quick changes to the feature design.

As this program is about rapidly evaluating potential new features, the specifics of what the participant will be helping with haven't been settled yet--but ideas are floating around security, privacy, UI, media, and file transfer.  Come join us and help build the next big thing in Firefox.


Experimentation Engineering Intern (Portland OR, or Mountain View, CA)

As an Experimentation Engineering Intern you will work on SHIELD, Pioneer, Fathom, Context Graph, and other R&D efforts that enable us to better understand our products, our users, and the web. You will work closely with experts in user research, machine learning, and applied mathematics on projects with immediate impact on millions of people.


Basic Qualifications:

  • Currently enrolled in a Bachelor’s or Master’s degree program in Computer Science, Computer Engineering, or related technical discipline with a focus on software development, with graduation dates starting December 2018 and onward
  • Or, recent graduate from a Coding Academy (within last 6 months)


Preferred Qualifications:

  • Strong understanding of web technologies such as JavaScript, HTML, and CSS
  • Knowledge of JavaScript frameworks
  • Ability to effectively articulate technical challenges and solutions
  • Adept at handling ambiguous or undefined challenges through strong problem solving abilities
  • Ability and passion for working in the open and engaging with Mozilla’s global community.
