Our capabilities include cyber space operations, cyber defense and resiliency, vulnerability research, ubiquitous technical surveillance, data intelligence, lifecycle mission enablement, and software modernization. Nightwing brings disruptive technologies, agility, and competitive offerings to customers in the intelligence community, defense, civil, and commercial markets.\nSoftware Developer (System Security)\nJoin Nightwing's Products team and work at the cutting edge of multi-layered cyber resiliency solutions protecting mission-critical systems. Our software-based cyber resiliency solutions have been field-deployed since 2009, protecting the confidentiality and integrity of data and applications on Department of Defense weapon systems and platforms. Our threat model assumes adversaries have gained escalated privileges and bypassed traditional security controls-we build the last line of defense.\nWe're seeking a sharp, seasoned software developer to strengthen our flagship security products, which provide deep OS-level protections for Windows, Linux, and VxWorks environments. You'll develop security capabilities that lock down execution environments, protect applications and data at rest and during execution, and implement robust cyber detection and response mechanisms.\nThis role is ideal for an experienced systems programmer who wants to dive deep into operating system internals and low-level security engineering. While you don't need to be a kernel developer today, you should be excited about becoming one and have the foundation to get there quickly.\nSecurity Clearance:\nMust meet the requirements to obtain and maintain a Secret government security clearance\nU.S. Citizenship is required. Qualified applicants may be subject to a security investigation and must meet minimum qualifications for access to classified information.\nRequired Qualifications:\n5+ years of professional software development experience in systems-level programming\nExpert-level C/C++ skills with a deep understanding of memory management, pointers, and low-level programming concepts\nStrong OS-level systems programming experience - you've built more than desktop applications; you understand how the OS actually works under the hood\nDebugging complex systems issues - comfortable using tools like gdb, WinDbg, Visual Studio Debugger, or similar to diagnose crashes, memory corruption, and system-level problems\n Version control proficiency (Git) in a team environment\nSelf-directed learning ability - proven track record of independently mastering new technical domains\nWhat Sets Qualified Candidates Apart:\nYou don't need all of these, but strong candidates typically have several:\nExperience working close to the OS: kernel modules, device drivers, system services, OS internals projects, or security tools\nBackground in security-sensitive code: anti-malware, EDR, security monitoring, or exploit mitigation\nUnderstanding of operating system concepts: process/thread management, memory management, I/O systems, interrupt handling\nAssembly language experience (x86_64, ARM) - reading and debugging at the instruction level\nExperience with scripting languages (Python, Batch) for automation and testing\nFamiliarity with security concepts: cryptography, threat modeling, attack surfaces\nKnowledge of boot processes, firmware, or hardware security (TPM, Secure Boot, UEFI)\nUnderstanding of Linux Driver Model and/or Windows driver models (WDM/WDF/WDK) - even if just conceptual\nWhat Disqualifies Candidates:\nTo be direct about fit, this role is likely not a good match if your primary experience is:\nWeb development, mobile apps, or enterprise application development\nHigh-level languages only (Java, C#, JavaScript, Python) without C/C++ depth\nLimited exposure to systems programming or OS-level concepts\nPrimarily cloud services, DevOps, or infrastructure automation\nLess than 3-4 years of professional development experience\nWhat You'll Work On:\nDeveloping and enhancing OS-level security features that operate deep within the operating system\nBuilding detection and response mechanisms to counter advanced persistent threats\nImplementing cryptographic binding of sensitive software to trusted hardware\nCreating system lockdown capabilities that minimize attack surface\nIntegrating with Hardware Root of Trust (HRoT) solutions\nProtecting against sophisticated attacks from well-funded adversaries\nSupporting multi-OS platforms (Windows, Linux, VxWorks)\nLearning kernel programming and driver development on the job with mentorship from our senior engineers\nOur Ideal Candidate:\nYou're a strong systems programmer who gets excited about understanding how things work at the lowest levels. You've probably compiled your own kernel, reverse-engineered a binary for fun, or spent late nights in a debugger tracking down a race condition. You're comfortable reading documentation, source code, and assembly when needed. You don't have all the answers, but you know how to find them and you're energized by deep technical challenges. You understand that security is an adversarial discipline and you're ready to think like both builder and attacker.\nWhy Join Our Team:\nWork on technology protecting critical DoW weapon systems and platforms\nLearn from senior engineers with over 15 years of experience in mission-critical system protection\nGrow your expertise in Linux/Windows internals, kernel development, and low-level security\nContribute to a multi-layered cyber resiliency portfolio that spans hardware, firmware, software, and network layers\nSee the direct impact of your work on national security\nAccess to cutting-edge tools, training, and technologies\nRecognition for exceptional results\nU.S. citizenship is required, as only U.S. citizens are eligible for a security clearance.\nPreviously part of a leading Fortune 100 company and headquartered in Dulles, VA; Nightwing became independent in 2024 but continues to support the nation’s most mission impactful initiatives.\nWhen we formed Nightwing, we brought a deep set of credentials and an unfaltering commitment to the mission.
