RapidFort, Inc. - Senior OS Engineer — Linux Security & Container Supply Chain
Requirements
• 5+ years in Linux systems engineering, OS engineering, platform engineering, DevSecOps, or release engineering • Deep expertise in Linux operating systems and distributions (Debian, RHEL, Ubuntu, Alpine) • Strong experience with OS package management systems (apt, rpm, dnf, apk) • Hands-on experience patching, rebuilding, or maintaining OS packages • Technical Depth • Strong understanding of Linux internals (processes, memory, filesystem, system libraries) • Experience working with system-level libraries and dependencies (glibc, openssl, etc.) • Deep knowledge of dependency resolution, ABI compatibility, and package lifecycle management • Experience with container internals and Linux runtime behavior • Security & Supply Chain • Experience remediating CVEs in OS packages and container environments • Understanding of SBOMs, software provenance, signing, and artifact trust models • Familiarity with supply chain security frameworks (e.g., SLSA, reproducible builds) • Strong scripting/programming ability in Python, Bash, Go, or C/C++ • Experience building CI/CD pipelines for OS or system-level build processes • Strong debugging skills across Linux systems and build environments • Experience contributing to or maintaining Linux distributions or open-source OS projects • Experience building minimal, distroless, or hardened container images • Familiarity with package build infrastructure (Koji, OBS, Launchpad, mock, etc.) • Experience with kernel hardening or low-level OS security modules • Knowledge of large-scale container security platforms • Contributions to open-source security, Linux, or container ecosystems • What Success Looks Like • Rapid and reliable remediation of OS-level CVEs across supported distributions • Stable and secure base images with minimal attack surface • Automated, repeatable OS patching and build pipelines • High-confidence SBOMs and supply chain transparency across all artifacts • Robust, reproducible OS build and packaging systems
Benefits
• Own end-to-end CVE remediation across Linux OS packages and system libraries • Analyze vulnerabilities affecting core OS components (glibc, openssl, kernel modules, runtime libraries, etc.) • Validate upstream fixes and determine patching or backporting strategies • Rebuild, patch, and curate OS packages across multiple Linux distributions (Debian, RHEL, Alpine, etc.) • Container Image Hardening • Build and maintain secure, minimal, production-ready container images • Remove unnecessary packages and reduce image attack surface • Ensure OS-level changes propagate safely into container environments • Validate image integrity, compatibility, and runtime stability • Supply Chain Security • Generate and maintain SBOMs for OS packages and container images • Implement provenance, signing, and artifact trust mechanisms • Ensure reproducible and verifiable builds across OS components • Strengthen software supply chain security across all image pipelines • Automation & Build Systems • Design and scale automated pipelines for OS patching, package rebuilding, and image generation • Integrate CVE scanning, remediation, and validation into CI/CD workflows • Build tooling for OS-level dependency tracking and vulnerability analysis • Improve build efficiency, reliability, and reproducibility • Cross-Functional Collaboration • Partner with platform, DevOps, infrastructure, and security teams • Work closely with engineering teams to integrate secure OS layers into product pipelines • Support production environments with stable, secure OS baselines • This role is foundational to RapidFort’s mission of eliminating vulnerabilities in containerized environments. Every secure container image begins with a secure OS layer, and this role ensures that foundation is trusted, minimal, and continuously hardened. • This Senior OS Engineer role offers a base salary range of $150,000 – $200,000, depending on experience and technical depth. In addition to base compensation, RapidFort provides a competitive benefits package including health, dental, and vision insurance, paid time off, and equity participation. Total compensation is designed to reflect the critical nature of this role in securing Linux-based systems, container images, and software supply chain infrastructure at scale. • $150,000 – $200,000
