Job Summary

Senior CNO Developers at Nightwing 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, both developing and defeating new and advanced security techniques. Senior CNO developers need to have leadership experience and working with customer stakeholders to drive requirements for small to medium sized projects over the course of their development, test, and release cycles. All our engineers write code, but many of our engineers 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.
