Job Description
Job #217683

Chipton-Ross is seeking a Software Engineer for a contract hybrid position in Owego, NY.

REQUIREMENTS

• Minimum 2 years of professional experience developing, building, and debugging Linux kernel modules (C language, kbuild/DKMS).
• Strong knowledge of core Linux internals (process scheduling, memory management, synchronization primitives).
• Proficient in systems level C programming and familiar with kernel coding style and static analysis tools.
• Demonstrated understanding of secure coding practices for kernel space (avoid leaks, race conditions, proper error handling).
• Experience working with SELinux/AppArmor or similar LSM frameworks in a production environment.
• Active Secret security clearance.
• Effective written and verbal communication skills; proven ability to produce clear design documentation and work within cross functional teams.

RESPONSIBILITIES

We are seeking a senior level Linux kernel engineer to design and implement a kernel level solution that intercepts VFS read/write operations, pins user memory pages, builds scatter gather DMA tables, and offloads the data to a cryptographic accelerator (hardware engine or user space process). The engineer will collaborate with hardware, security, and software teams to deliver a stable, high performance, and secure off load path that complies with Lockheed?Martin coding standards and regulatory requirements.

DESIRED

• VFS & kprobe/kretprobe - Implemented handlers for vfs_read, vfs_write, or similar VFS entry points.
• Page pinning & Memory Management - Used pin_user_pages_fast, get_user_pages, and managed pin count cleanup.
• Scatter Gather / DMA engine - Built and populated struct sg_table / struct scatterlist; interfaced with dma_map_sg / dma_unmap_sg.
• Linux Crypto API - Registered and used symmetric/asymmetric algorithms via the Crypto API, including async request handling.
• Kernel Key Management - Managed cryptographic keys with the kernel keyring (keyctl, request_key) or integrated external KMS/HSM.
• User Space Communication - Designed netlink, character device, ioctl, or shared memory interfaces for status updates and key exchange.
• Testing & Profiling - Created kernel module unit tests (kselftest/kunit), used perf, ftrace, bpftrace for latency/performance analysis.
• Hardware Crypto Offload - Experience with Intel QAT, ARM TrustZone, FPGA based accelerators, or similar off load engines.
• Up stream Contributions - Submitted patches accepted to VFS, Crypto, DMA engine, or related subsystems.
• Trusted Execution Environments / Secure Enclaves - Worked with OP TEE, Intel SGX, or comparable TEEs.
• DPDK or High Performance User Space I/O - Familiarity with DPDK or similar frameworks for user space data paths.
• Certifications - Linux Foundation Certified Engineer (LFCE), CISSP, GSEC, or specialized hardware security training.
• Regulated Industry Experience - Prior work on aerospace, defense, or ITAR controlled projects with required documentation and audit practices.
