Upbound is hiring a Senior Software Engineer to help us build and operate Upbound Spaces, the multi-control-plane management software at the heart of the Upbound Platform.

As part of the Spaces team, you’ll help us scale Upbound to reliably support thousands of control planes while extending enterprise-grade control plane management and operations across both cloud and on-premises environments.

For this particular opening, we’re focused on growing our engineering presence in the San Francisco Bay Area and Seattle, and are prioritizing candidates who are currently based in, or able to work from, one of those two markets.
