1d•$150,000 - $180,000

About The Position

Markon is seeking a CNO Developer Level 2 to support advanced vulnerability research, reverse engineering, and development of capabilities targeting complex software and embedded systems. This role involves deeper technical analysis of operating systems, network protocols, and low-level architectures, with responsibility for developing and operationalizing exploits. The developer will work both independently and as part of a team to deliver mission-focused cyber capabilities.

Requirements

Active TS/SCI W/ Polygraph
Bachelor’s degree in Computer Science, Engineering, or related field with 10+ years of experience
Demonstrated experience with Assembly, C, C++, and/or Python
Strong understanding of operating system internals (Windows, Linux, iOS, Android)
Experience with vulnerability research and exploit development
Experience reading and writing assembly across multiple architectures (x86, x64, ARM, PPC, MIPS, etc.)
Proficiency with reverse engineering tools (e.g., IDA Pro, Hex-Rays, Ghidra, Binary Ninja, objdump)
Experience using debugging tools (e.g., gdb, WinDbg, OllyDbg)
Experience with embedded systems and hardware interfaces (e.g., JTAG/BDI)
Strong understanding of network protocols (TCP/IP, routing protocols, RF communications, etc.)
Knowledge of exploit mitigations such as DEP and ASLR
Experience with modern C++ (e.g., C++11/14, RAII)
Experience building tools to identify, exploit, and operationalize vulnerabilities
Ability to work independently and collaboratively within a team environment

Responsibilities

Conduct vulnerability research on complex software systems, operating systems, and embedded platforms
Perform reverse engineering using tools such as IDA Pro, Ghidra, Binary Ninja, and related technologies
