Responsibilities :
- Triage incoming CVEs using NVD, CVSS/EPSS scores, and CISA KEV data; prioritize backport work by risk severity
- Write and apply C/C++ patches for EOL packages (CentOS 6/7/8) where upstream fixes are unavailable or inapplicable
- Build, test, and sign RPM packages using mock, rpmbuild, and GPG; maintain spec files and package metadata
- Debug regressions and build failures with gdb, strace, and valgrind; resolve symbol, linkage, and ABI issues
- Collaborate with reviewers to meet quality gates; respond to technical review feedback on patch correctness and security impact
- Document remediation decisions, patch rationale, and build reproduction steps in Jira and Confluence
- Contribute to automation improvements (CI pipelines, scripted build environments) to increase team CVE velocity
Requirement :
- 12+ years of professional C and C++ development and system admin level experience on Linux systems.
- RPM packaging expertise — Hands-on experience with RPM packaging:
- Writing and maintaining .spec files, understanding of rpm build phases and macros
- Building in isolated environments using mock; managing dist tags and dependencies
- Deep Linux internals – Strong Linux internals knowledge:
- Kernel subsystems (memory management, process scheduling, file systems, networking stack)
- System calls, device drivers, and kernel module development fundamentals
- Package management proficiency with yum/dnf and familiarity with rpm database operations
- Practical debugging skills: gdb, strace, ltrace, valgrind, core dump analysis
- Scripting in Bash and Python for build automation and tooling
- Familiarity with SELinux policy analysis and enforcement modes
- Experience with git and git-lfs for patch management and source control
Nice to Have :
- Prior experience backporting security patches for EOL distributions (CentOS, RHEL, Oracle Linux, Rocky, AlmaLinux)
- Knowledge of OpenSSL, libxml2, openldap, or Ruby C extensions at the source level
- Familiarity with CVSS v3/v4 scoring, EPSS, and KEV prioritization workflows
- Experience with virtualization tooling: libvirt, QEMU/KVM, Vagrant, VirtualBox
- CI/CD pipeline experience (Jenkins, GitHub Actions) for automated package builds
- Understanding of networking layers (L2/L3), socket programming, and network-facing service hardening
- Exposure to CIS Benchmarks or DISA STIGs for hardened image configuration
All employees are expected to demonstrate AI fluency appropriate to their role and level, including responsible use of AI tools, sound judgment, and adherence to company AI governance and security policy standards.
