About Nightwing

Nightwing provides technically advanced full-spectrum cyber, data operations, systems integration, and intelligence mission support services to meet our customers' most demanding challenges. For over four decades, our team has delivered these capabilities to the U.S. government on its most important missions. We bring disruptive technologies, agility, and competitive offerings to customers in the intelligence community, defense, civil, and commercial markets.

At Nightwing, we value collaboration and teamwork. You will have the opportunity to work alongside talented individuals who are passionate about what they do. Together, we leverage our collective expertise to drive innovation, solve complex problems, and deliver exceptional results for our clients.

About the Role

Vulnerability Researchers at Nightwing CODEX analyze systems to understand how they work and how they behave when they break. Candidates must be able to play both sides of the fence, developing and defeating new and advanced security techniques. Projects are undertaken in small teams with close coordination with customers.

While all our engineers write code, many spend as much time taking systems apart as building new ones. A typical day can involve studying disassembly or writing Python to audit a piece of C++ code. We invite you to join us as we embark on this new journey and shape the future of cybersecurity and intelligence together.

Equal Opportunity

Nightwing is an Equal Opportunity/Affirmative Action Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, veteran status, age, or any other federally protected class.
