Responsibilities

Conduct technical analysis of target platforms, including discovery of zero-day vulnerabilities through fuzzing and code analysis.
Reverse engineer software applications, firmware, and hardware components using disassemblers, debuggers, and binary analysis tools.
Discover vulnerabilities through automated fuzzing, manual code review, and dynamic and static analysis techniques.
Rapidly prototype proof-of-concept exploits to validate findings and assess operational utility.
Analyze target system architectures, protocols, and security mechanisms to identify attack surfaces and weakness patterns.
Document vulnerability technical details, exploitation methodology, and recommended capability development approaches.
Provide technical intelligence briefs to capability developers on target system weaknesses and exploitation pathways.
Collaborate with capability development teams to translate vulnerability research into operational tools.
Maintain awareness of public vulnerability disclosures, exploit techniques, and adversary tradecraft relevant to target systems.
Apply offensive cyber domain expertise, including red/purple team operations, to develop and deliver mission-critical solutions.
Conduct limited TDY travel as mission requires.
