KBR is seeking a Vulnerability Researcher to support vulnerability discovery and validation efforts against embedded systems and firmware. In this role, you will focus on handson vulnerability research, including building emulationbacked test environments, developing fuzzing workflows, performing crash triage and rootcause analysis, and assisting with proofofconcept exploit development in a controlled lab setting.

The Vulnerability Researcher works closely with reverse engineers and senior vulnerability researchers to deliver reproducible findings and highquality technical documentation for government customers while continuing to deepen technical proficiency across missionrelevant domains.

Key Responsibilities

• Conduct vulnerability research on embedded targets using assetsafe approaches such as emulation, virtualization, and controlled experimentation
• Develop and execute fuzzing campaigns, including target setup, fuzz harness development, seed/corpus management, and coveragedriven testing
• Perform crash triage and rootcause analysis to identify and characterize security vulnerabilities
• Assist in the development of proofofconcept exploits to validate vulnerability impact in controlled laboratory environments
• Create and maintain test harnesses and supporting infrastructure to exercise payload delivery and validate behavior repeatably
• Reverse engineer firmware and binaries as needed to understand vulnerable code paths and exploitation constraints
• Collaborate with vulnerability researchers, reverse engineers, and developers support mission objectives
• Document findings and produce technical reports and artifacts suitable for release
• Research and apply new vulnerability research tools and techniques under senior technical guidance

Minimum Qualifications

• Security Clearance: Must have an active U.S. government Secret security clearance, which is something only a U.S. citizen can obtain
• Bachelors degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field
• 49 years of experience in vulnerability research, reverse engineering, or exploit development
• Strong understanding of embedded systems, firmware, operating systems, and lowlevel software behavior
• Proficiency in C/C++, Python, and assembly for vulnerability research, harness development, and automation
• Experience with embedded emulation environments
• Experience with coverageguided fuzzing, fuzz harness development, and crash triage workflows

Preferred Qualifications

• Experience developing proofofconcept exploits for vulnerability validation
• Exposure to analysis techniques such as symbolic execution, concolic execution, or taint analysis
• Experience with hardwarefocused vulnerability research or embedded security testing
• Demonstrated ability to communicate technical findings clearly in written reports

Basic Compensation:$99,200 - $148,700 (For Beavercreek, OH Only)
The offered rate will be based on the selected candidates knowledge, skills, abilities and/or experience and in consideration of internal parity.
