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 and Toronto!

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.

Research Intern

Mozilla is looking for PhD (or motivated MS) level interns to take on various projects within our Research Group. Past interns have done substantial work in Language Design, Compiler Optimizations, Garbage Collection, Static/Dynamic Analysis, Record-and-Replay Debugging, Parallel Algorithms, Graphics, Video Codecs, and Web Application Optimization. Your work will be highly visible and fully open, just like the rest of Mozilla. We’ve put together a list of possible research topics for this particular term, but we’d love it if you have research ideas of your own to bring to the group. As always, we strongly encourage our research interns to submit their results to relevant academic conferences. To apply, submit your resume via the online form located below.

Servo Intern (San Francisco, CA)  

Servo is Mozilla’s next-generation research web engine, written in the Rust programming language, which balances processor, memory, and energy efficiency with the safety of a modern statically typed language. Servo is part of the Mixed Reality research group, and is our testbed for features targeted at 3D immersive web experiences.

As an intern, you would help improve the security, efficiency, or support for new web technologies in Servo. Projects might include Spectre mitigation, safety of worker threads, constant time cryptography, new web APIs such as shared memory or immersive web content, or another topic depending on the skills and interests of the intern. If you have other research ideas which align with Servo’s goals (such as parallelism, distributed systems, memory safety, or garbage collection integration), please apply.

Basic Qualifications:

  • Currently enrolled in a Master’s or PhD program in Computer Science, Computer Engineering, or related technical discipline with a focus on software development
  • Must be currently enrolled in university with graduation dates starting December 2019 and onward or have graduated from a Coding Academy within last year

Preferred Qualifications:

  • Research interests which align with the Servo project
  • Prior experience with reading/writing Rust code
  • Experience solving systems-level problems (such as crashes, intermittent errors, or concurrency bugs)

General Qualifications

  • Ability to quickly learn and be effective within a large code base
  • Experience with writing and publishing academic papers
  • Interest in web technology
  • Excellent research and writing skills
  • Ability to interpret large amounts of data, multi-task, and produce results independently and collaboratively in a team

Note that this is a long wishlist of qualifications: if you feel you have some but not all of these skills, but you are interested, please do apply anyway.

**Please include a cover letter describing your research topic and/or dissertation topic and relevant project choice/area of interest.**

Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Voluntary Self-Identification of Disability

Why are you being asked to complete this form?

Because we do business with the government, we must reach out to, hire, and provide equal opportunity to qualified people with disabilities1. To help us measure how well we are doing, we are asking you to tell us if you have a disability or if you ever had a disability. Completing this form is voluntary, but we hope that you will choose to fill it out. If you are applying for a job, any answer you give will be kept private and will not be used against you in any way.

If you already work for us, your answer will not be used against you in any way. Because a person may become disabled at any time, we are required to ask all of our employees to update their information every five years. You may voluntarily self-identify as having a disability on this form without fear of any punishment because you did not identify as having a disability earlier.

How do I know if I have a disability?

You are considered to have a disability if you have a physical or mental impairment or medical condition that substantially limits a major life activity, or if you have a history or record of such an impairment or medical condition.

Examples of reasonable accommodation include making a change to the application process or work procedures, providing documents in an alternate format, using a sign language interpreter, or using specialized equipment.
