Why Mozilla

Mozilla Corporation is the non-profit-backed technology company that has shaped the internet for the better over the last 25 years. We make pioneering brands like Firefox, the privacy-minded web browser, and Pocket, a service for keeping up with the best content online. Now, with more than 225 million people around the world using our products each month, we’re shaping the next 25 years of technology and helping to reclaim an internet built for people, not companies. Our work focuses on diverse areas including AI, social media, security and more. And we’re doing this while never losing our focus on our core mission – to make the internet better for people.

The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation. This means we aren’t beholden to any shareholders – only to our mission. Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms.

About this team and role:

The Sync team is looking for a senior software engineer who is motivated by curiosity, continuous learning and working collaboratively in the open. If you already know why Rust is the most-loved programming language (or maybe you are ready to learn it and love it too), we'd like to talk with you about joining Mozilla, where you can help our small, distributed team bring the connected Firefox experience to more of our global users.

What you’ll do:

• Provide Firefox users with a seamless experience to access and control their personal and browsing data (history, bookmarks, logins and more) across all of their devices.
• Help us evolve the Application-Services library at the core of our sync and storage features, and continue to support its implementation in Firefox on all platforms.
• Grow your knowledge of the Firefox browser to support Sync and Send/Close tab functionality across devices.
• Partner with engineers on and off the Sync team to deliver features that strengthen the utility and agency of Firefox for our users.
• Provide constructive feedback, timely reviews and well-documented ideas to help us improve our team practices and skills.

What you’ll bring:

• You enjoy and have experience using low-level languages such as C++, Golang or Rust to solve tough problems.
• You have strong knowledge of web or native application development in JavaScript, Kotlin or Swift and have shipped complex applications at scale.
• You are trusted to work independently because you coordinate with your colleagues to understand the business value, operational impact and security implications of your changes.
• You clearly express your ideas and increase your impact by sharing what you learn through documentation and demos.

What will make this even better:

• You are comfortable working collaboratively with a remote and globally distributed team, often iterating on ideas asynchronously.
• You want what you ship to have a positive impact on the user experience, as well as the team's objectives.
• You are curious by nature and enjoy taking on complex tasks that are outside your existing knowledge domain – but you’re not afraid to seek help when needed.
• You've also worked with multi-functional teams on desktop or mobile applications.

What you’ll get:

• Generous performance-based bonus plans to all eligible employees – we share in our success as one team
• Rich medical, dental, and vision coverage
• Generous retirement contributions with 100% immediate vesting (regardless of whether you contribute)
• Quarterly all-company wellness days where everyone takes a pause together
• Country specific holidays plus a day off for your birthday
• One-time home office stipend
• Annual professional development budget
• Quarterly well-being stipend
• Considerable paid parental leave
• Employee referral bonus program
• Other benefits: life/AD&D, disability, EAP, etc. (varies by country)
