- Development of modular implants or payload frameworks
- Process injection or similar low-level techniques
- Command and Control (C2) systems (e.g., Mythic, Cobalt Strike, Vermilion Strike)
- Network stack programming (sockets, protocols, TCP/IP)

Preferred Experience

8 years experience
Strong background in *nix environments (Linux preferred)
- Windows expertise will be considered with equivalent depth
Demonstrated experience building complex offensive tooling end-to-end
- Highly desirable: experience developing and cross compiling a full Remote Access Tool (RAT)
