We are looking for an experienced and versatile software engineer to work on the tools and systems that support Firefox engineering.
This is a broad software engineering role spanning internal engineering systems, developer tooling, workflow automation, and the infrastructure required to operate them. We are looking for an engineer with strong software development skills and meaningful experience deploying and operating production systems.
Our Cloud Engineering teams provide shared platforms and foundational services, while engineering teams own the applications and services they run on them.
