The Firefox Platform Layout team is a global community of engineers who care deeply about how the Web looks and feels. We are the team responsible for Page Layout, CSS, images, text, printing, and animations in Gecko, the engine behind Firefox. We strive to build and maintain an engine that is both high-performance and standards-compliant, while providing support for features unique to Firefox. Are you the type of software engineer who wants to collaborate with other driven, committed team members to help bring new capabilities to the Open Web for millions of people? Do you have experience with either C++ or Rust? If so, we'd love to hear from you!

On our team, you will be able to design and develop standards-compliant CSS and page layout features that all of our users see, with a current particular focus on Asynchronous Pan and Zoom (APZ), our technology for making user interaction snappy and delightful.  You will be helping make the Web Platform more usable, accessible, beautiful, and interactive over time.  We are looking for Engineers with experience in C++ and/or Rust. You’ll be responsible for writing code, tests, specifications, building prototypes, solving problems, and analyzing data. You are a self-starter who wants to have a direct, immediate impact on the web.

Our team is geographically-distributed, and working virtually and in the open is the norm. You can expect to work on the code driving the Firefox browser on a number of platforms - Android, Windows, Linux, and macOS. Our focus is on writing fast, lightweight and maintainable code to make Firefox phenomenal for users.

What You’ll Do:

• Work cooperatively with other Mozillians to identify and correct issues, and ask for help as needed
• Write high-quality, performant, open source, and standards compliant code
• Develop innovative layout, graphics, and user interaction techniques, algorithms and tools to maximize the rendering quality and performance of Firefox
• Participate in regular code reviews, team meetings and long-term planning
• Help triage and test bugs, taking the initiative to drill down to root causes and explore potential solutions

• Bachelor’s degree or equivalent experience in Computer Science or similar field
• Experience developing C/C++ and/or Rust applications
• Strong debugging and optimization skills in a multi-threaded environment
• Experience with memory and performance optimizations tools
• Excellent written and verbal communication skills
• Proven record of finishing projects where the work spans several months
• Ability to quickly learn and be effective with a large code base

Bonus points if you have any of the following:
