From the job listing:
We are looking for a software engineer who is excited about becoming part of Rust’s infrastructure and/or crates.io teams. As a member of these teams, you will
- improve the Rust project’s development infrastructure, including continuous integration, build artifact generation, GitHub bots, and other development workflows.
- help develop crates.io, the central package manager for Rust
- help develop related components to crates.io, for example custom private registries and cached binaries
As Rust is an open-source project, a big focus for this role is collaboration and mentorship. You will work with people from both inside and outside of Mozilla. You should have experience in back-end server and operations work. Some experience with AWS and CI systems like Travis and AppVeyor would be a plus. Development work will primarily be in Rust.
