Our work touches millions of users every day, combining strong engineering practices with Mozilla’s values of openness, privacy, and accessibility.

We collaborate across engineering, creative, and product teams to deliver performant, reliable, and privacy-respecting web experiences that help advance Mozilla’s mission.

As a Backend Engineer (P2) on the Websites & MarTech team, you’ll contribute to the design, development, and maintenance of high-traffic websites and supporting services. You’ll work closely with frontend developers, site reliability engineers, designers, and data and marketing partners to create scalable, maintainable systems that help us connect with users worldwide.

• An understanding of testing, monitoring and automation best practices.
• A collaborative mindset and the ability to work effectively on a remote, globally distributed team.
