Firefox Senior Engineer - Sync

Remote Canada, Remote US

Location Details: Mozilla’s North American office locations include San Francisco, CA, Portland, OR, and Toronto, Canada. We are also open to you working from your home office anywhere in the US or Canada for this position.

Are you a curious software developer who is motivated by learning continuously and working collaboratively in the open? Perhaps you already know why Rust is the most-loved programming language, or maybe you are ready to learn it and love it too! If so, we'd like to talk with you about coming to work at Mozilla, where you can join our small distributed team to help 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 manage their personal browsing data (history, bookmarks, logins and more) across platforms and devices.
  • Work together with our team to get our new experimentation sdk and multi-language bindings generator tools production ready to support our internal experimentation platform.
  • Help us evolve the application-services library that is at the core of our new Firefox for Android browser sync and storage features; continue to support their implementation in Firefox for iOS and Firefox Desktop.
  • Grow your knowledge of the Firefox browser to support Firefox Sync and Send tab functionality across devices.
  • Provide constructive feedback, timely reviews and well-documented ideas to help us improve our team practices and skills.

What you already do:

  • You have experience using low-level languages such as C++, Golang or Rust to solve tough problems and it brings you joy.
  • You have strong knowledge of web app or native app development in JavaScript, Kotlin or Swift and have shipped complex applications at scale.
  • When building applications, you are trusted to work independently because you communicate with all colleagues to understand the business value, operational impact and security implications of your changes.
  • You clearly express your ideas to your peers and maximize your impact by sharing what you’ve learned through documentation and demos.

What will make you happier here:

  • You are comfortable working collaboratively with a remote and globally distributed team, often iterating on ideas asynchronously.
  • You provide constructive feedback to your peers; you receive feedback graciously.
  • A desire to ship well-crafted code which highlights your professionalism in its consideration for the user experience, positive impact on the team objectives balanced by the pragmatism of shipping.
  • You are curious by nature and enjoy tackling complex tasks that are outside your existing knowledge domain; you’re not afraid to seek help when needed.
  • You have experience beyond web applications where you’ve worked with multi-functional teams on desktop or mobile applications.
