PGS Worldwide is seeking a Linux Kernel Engineer in Owego, NY for a 7 month contract-to-hire role supporting a leading aerospace & defense company. This role focuses on developing a kernel-level solution to intercept VFS operations, manage memory, and offload data to cryptographic accelerators. You will work closely with hardware, security, and software teams to deliver high-performance, secure system capabilities.
Required Skills:
- Minimum 2 years of experience developing, building, and debugging Linux kernel modules using C (kbuild/DKMS)
- Strong knowledge of Linux internals including process scheduling, memory management, and synchronization
- Proficiency in systems-level C programming and kernel coding practices
