Job Description:

The Firefox team is a community of engineers who care deeply about delivering the fastest, friendliest, most usable browser possible. We are responsible for making the things you see in the browser work securely, quickly, and well! The Enterprise team is a cross-disciplinary team in charge of improving and maintaining Firefox support for large Enterprise deployments. As part of the team, you will be responsible for all things related to OS integration - such as updates, installs, and integrating Firefox with the different operating systems - and helping us grow our user base. Our team is geographically-distributed, and working in the open is the norm. We contribute to the code driving Firefox on a number of desktop platforms - Windows, Linux, and macOS. A Senior Software Engineer contributes to architectural discussions, and driving feature development within a team. At Mozilla, Senior Engineers are expected to work independently on scoped projects, collaborate closely with peers, and play a key role in delivering high-quality software that aligns with team goals.

Job Responsibility:

  • Develop, innovate, and ship the next experience of Firefox through improved integration with the operating system
  • Improve the ease of use and security of Firefox in large deployments by developing better administration and monitoring tools
  • Improve Firefox functionality by better integration with remote services
  • Assess what work supports the team and product roadmap and make insightful recommendations in regards to priorities
  • Optimize the quality of Firefox by hunting down and fixing software defects, improving the experience of hundreds of millions of users
  • Work with a geographically-distributed development team

Requirements:

  • Experience with systems programming on a major desktop platform (Windows, macOS or Linux)
  • A solid understanding of C/C++ and some knowledge of Rust
  • A solid understanding of JavaScript and typical interactions with the backend (services, REST, ... )
  • You are an excellent communicator and have participated effectively on a distributed team
  • You’re pragmatic about how to move things forward in specific timeframes including trade-offs and safeguards when implementing new functionality
  • Experience working collaboratively with product managers, project managers, and/or other non-engineering teams

Nice to have:

  • Professional programming experience in Rust
  • You have developed cross-platform desktop applications, particularly when this involves some low level systems programming such as Win32 APIs on Windows, Cocoa APIs on macOS or GTK on Linux
  • You have previously successfully contributed to an open source project
What we offer:
  • Generous performance-based bonus plans
  • Rich medical, dental, and vision coverage
  • Generous retirement contributions with 100% immediate vesting
  • Quarterly all-company wellness days
  • 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)
  • Flexible work environment
  • Industry-leading paid parental leave
  • Reimbursement for professional development (up to $3,000/year)
  • A work setup including the latest hardware and software of your choice
