Apply for this job
Emerging Technologies
Berlin, Portland, San Francisco, Toronto

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 have 4 positions open for the following roles:

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.

Aside from the general qualifications listed below, each project has its own list of preferred qualifications. As a Research Intern at Mozilla, potential projects you will work on include:

Servo (Berlin, Toronto, San Francisco)

Servo is a new web engine designed for maximum performance and safety on modern hardware architectures. Our goal is nothing less than building the fastest and most secure web engine. We’re looking for interns to take on projects in a variety of areas such as graphics, parallel algorithms, testing, JavaScript integration, and general performance improvements.

Some potential projects you could work on are:

  • Experimentally replace the browser’s memory allocator and the JS engine’s garbage collector
  • Building alternative backends for WebRender, our GPU-powered drawing subsystem, such as a PDF backend for printing
  • Finding new performance optimizations for popular benchmarks
  • Proving safety properties of our JS language integration
  • Adding audio and video support
  • Experimenting with security mitigations for C/C++ dependencies in Rust
  • Prototyping new CSS layout features

WebEmbedding (Berlin or PDX)

The WebEmbedding team is building an application development platform aimed at bringing the best of the modern web to application developers. Using the Rust systems programming language and Servo, the next generation browser engine coming out of Mozilla Research, we want to make an uncompromisingly modern development stack available to a broad audience: web frontend developers.
