Senior Backend Engineer; Rust

Metal Bear is building the next generation of developer tools for cloud engineers
. Our flagship product,
mirrord
, lets developers run local processes as if they were running directly inside their cloud environment — without the friction of deployment or risk of breaking shared environments. Mirrord’s open-source core is already trusted by thousands of developers worldwide
, and our paid product is generating meaningful revenue — including from Fortune 500 companies
. We’re scaling quickly and looking for an experienced Rust engineer to help us push mirrord to the next level. This is a rare chance to work on deep systems engineering challenges while building an open-source product that developers love.
