- Hands-on experience with IMA/EVM, dm-verity, cryptsetup, keyrings, and filesystem-level protections.

- Strong understanding of vulnerability management, CVE analysis, and Linux patching workflows.


Preferred Skills :


- Familiarity with secure software lifecycle practices and threat modeling frameworks (e.g., STRIDE, DREAD).

- Experience with custom Linux distributions using Yocto or Buildroot.

- Exposure to virtualization and container technologies such as KVM, Xen, Docker, LXC, or Kata Containers.

- Background in industries with high security and compliance requirements such as automotive, medical devices, or industrial systems.

- Understanding of compliance and security standards (e.g., FIPS, CIS Benchmark, GDPR, ISO 21434).
