About Flox
Flox gives engineering teams reproducible environments, built on the Nix package manager, that carry the same tools and dependencies from a developer's laptop through builds and deployment, with FloxHub for sharing them. Its board shows two openings, and one is a Security Engineer, the company's first dedicated security hire, working with engineering leadership to deploy tools, configure controls and harden infrastructure for a product at the center of the software supply chain. The job is remote.

A few links on CyberJobs.cc are referral links: when one leads to a hire, a sign-up or a purchase (a lab, a course or a tool marked Partner), the company behind it may pay CyberJobs.cc a fee. You pay nothing extra, and it never changes the salary an employer offers you or which roles the board lists.
