Senior Vulnerability Researcher/CNO Developer (Onsite)

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, both developing and defeating new and advanced security techniques. Projects are undertaken in small teams with close coordination with customers. All engineers write code, but 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.

This position is an onsite role.

• Experience with C or C++
• BS/MS in a technical discipline or equivalent work experience

• Understanding of network protocols (TCP/IP stacks, wire-level protocols, RF communications, BGP, routing protocols, or others)
• Understanding of exploit mitigations such as DEP and ASLR
• Experience using reverse engineering tools such as IDA Pro, HexRays, Ghidra, Binary Ninja, or objdump
• Experience using debuggers such as gdb, WinDbg, OllyDbg
• Experience building and using tools to find, exploit, and productize vulnerabilities in complex software systems
