Mozilla is hiring Software and Research Engineering Interns into our technical teams throughout the world. Our headquarters are based in the Bay Area, which is where this internship will be located.

We are engineers, researchers, 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 or researcher, 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 engineer, 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 have 4 positions open for the following roles:

Networking and Security Intern (Mountain View, CA)

Firefox Advanced Technology is looking for PhD (or motivated MS) level interns with previous intern experience on WebRTC, privacy-preserving advertising, and analysis of Transport Layer Security (TLS). Our group focuses on developing advanced technology and standards in the following areas; Networking, Security, Voice/Video (WebRTC, DRM) and Privacy.

Privacy Research Intern (Mountain View, CA)

My team focuses on online privacy. We would like to have an intern help develop a way to improve detection of online trackers with machine learning.

Detecting online trackers is still primarily a manual effort. That effort can be slow, complex, and difficult to maintain. Researchers have explored machine learning to improve detection of online trackers, with some promising results. But, the research is primarily based on “crawlable” web data.

Firefox is in a unique position to apply these concepts to real-world online activity and data, and to implement specific user protections. E.g., we can scale the degree of technical limitation applied - from restricting storage to resisting fingerprinting to completely blocking connections - with the degree of confidence in the classification of the tracker.

This project is to build a machine learning model trained on both crawl data and real user activity data, measure its efficacy, and apply it to improve Firefox’s Tracking Protection & Content Blocking features.

Privacy Research Intern (Mountain View, CA)

Advanced work in online privacy and security. Mozilla recently announced that it will take an active role in protecting users against web tracking and other harmful practices that are commonplace on the web. In your internship, we will work together to design, prototype, and evaluate techniques to protect users against advanced forms of tracking and related harmful practices. Projects that lead to publishable research results are preferred. The ideal candidate for this role will have research experience and strong technical skills.

Security Research Intern (Mountain View, CA)

Topics in security and privacy. As an intern, we will work together to define a specific project topic that aligns with your research area as well as the research interests of Mozilla. Working with Mozilla engineers, you will actively participate in the research effort, producing any publishable research papers that may derive from this work. This role is open to PhD students.

Basic Qualifications:

  • Currently enrolled in a Bachelor’s, Master’s or PhD degree program in Computer Science, Computer Engineering, or related technical discipline with a focus on security and privacy. We accept students with graduation dates starting December 2019 and onward.
  • Familiarity with networking, web security, and web privacy concepts

Preferred Qualifications:  

  • Experienced in C / C++, Javascript, or Python development (depending on the project)
  • Understanding of web tracking, machine learning, or cryptography concepts. We will match candidates to the role that fits their expertise.
  • Reasonable fluency in and passion for technology, excellent research and writing skills, strong communication and social skills
  • Strong analytical and critical thinking skills

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.
