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.\r\nPrincipal Software Developer (System Security)Join 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.\r\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.\r\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.\r\nSecurity Clearance:Must meet the requirements to obtain and maintain a Secret government security clearance.\r\nU.S. Citizenship is required.
