Senior C/C++ DeveloperExperience Level

Senior (6–10+ years)

Overview

We are seeking a highly skilled and experienced Senior C/C++ Developer with a deep understanding of system-level programming, file system architecture, storage devices, and data recovery/destruction technologies. The ideal candidate will have a strong foundation in OS internals, an analytical mindset for forensic data handling, and hands-on experience developing utilities for disk repair, low-level access, and secure data handling.

You will contribute to the design and development of high-performance tools used in environments where data accuracy, integrity, and confidentiality are paramount — such as secure enterprise environments, government, forensic labs, and data centers.

Key Responsibilities

·Design and develop robust, performant, and fault-tolerant utilities and libraries in C/C++.

·Implement data recovery techniques for inaccessible, corrupted, or deleted files.

·Develop data wiping and destruction utilities aligned with standards (NIST 800-88, DoD 5220.22-M, Gutmann method).

·Integrate hardware-level communication (SATA, NVMe, SCSI) for low-level device interaction.

·Analyze raw disk images, memory dumps, and corrupted partition tables.

·Optimize read/write operations for large volumes in degraded environments.

·Develop disk cloning, metadata carving, hash-based validation, and integrity verification tools.

·Interface with bootloaders, UEFI/BIOS, and pre-boot environments.

·Lead code architecture, mentor junior engineers, and ensure adherence to secure coding practices.

·Document internal tools, algorithms, and best practices for cross-functional collaboration.

Technical Requirements

·Proficiency in C and C++ (C11/C++14 or later) for systems-level development.

·Strong background in Windows and Linux system internals (WinAPI, POSIX, kernel I/O stacks).

·Understanding of file systems: NTFS, FAT32, exFAT, ext3/ext4, APFS, XFS, HFS+.

·Hands-on experience with disk-level data recovery, including MFT, GPT, boot sectors, and journaling file systems.

·Practical knowledge of secure erasure techniques and device-specific commands

·Familiarity with disk imaging, hex editors, partition editors, and forensic toolkits

·Familiarity with RAID, disk encryption, and wear-leveling impacts on recovery/destruction.

Preferred Experience

·Development of bootable recovery environments (e.g., Linux live systems, PXE boot).

·Firmware-level programming or reverse engineering experience.

·Digital forensics exposure, including evidence preservation and chain-of-custody procedures.

·Script automation in Python or Bash for recovery and wiping workflows.

·Familiarity with secure enclave, TPM, or self-encrypting drive (SED) architectures.

·

Soft Skills & Expectations

·Exceptional problem-solving and low-level debugging skills.

·Able to analyze undocumented file structures and non-standard behavior.

·Clear and concise communicator across technical and non-technical audiences.

·Proactive, self-driven, and capable of working independently and in collaborative teams.

Education & Certifications

·Bachelor's or Master's degree in Computer Science, Computer Engineering, or a related field.
