Key skills for this role
RapidFort is looking for a deeply technical Senior OS Engineer to design, build, and maintain secure Linux-based operating system components that power hardened container images and cloud-native workloads.
This role sits at the intersection of Linux systems engineering, package management, and software supply chain security. You will be responsible for identifying vulnerabilities in OS packages, validating fixes, rebuilding or patching components, and ensuring secure, production-grade container images are delivered at scale.
You will work across multiple Linux distributions to curate, harden, and continuously improve the operating system layers used in containerized environments. This includes package-level remediation, dependency resolution, and automation of secure build pipelines.
This is a hands-on engineering role focused on Linux internals, OS packaging, and container image security — not just vulnerability scanning or policy enforcement.
