Title:

Cybersecurity Practitioner

KBR is seeking a Cybersecurity practitioner with experience in software development, software assurance, and risk management to evaluate and verify third-party software deliverables, assess technical compliance reports, and provide risk‑mitigation recommendations for Information Technology (IT) and Operational Technology (OT) systems. The successful candidate will join a team that evaluates cybersecurity policies and implements the National Institute of Standards and Technology (NIST) Risk Management Framework (RMF) to assess, authorize, and monitor system risks and ultimately ensure mission success for the customer. The successful candidate will conduct Static Application Security Testing (SAST) on source code and static binary analysis on compiled executables, assess scan reports to identify software weaknesses and prioritize mitigation plans, and maintain various security testing tools. The successful candidate will reverse engineer commercial and custom software to identify software flaws, logic defects, or undocumented embedded objects. The successful candidate will leverage expertise in Development, Security, and Operations (DEVSECOPS) and secure coding practices to provide technical support that effectively directs system security engineering for acquisition and sustainment programs. The successful candidate will develop and maintain custom software utilities to gather computer system information, consolidate logs and Security Content Automation Protocol (SCAP) results, generate visual metrics, and produce Continuous Monitoring (CONMON) artifacts.

REQUIREMENTS

The position requires at least three (3) years of experience in software engineering, software development or a cybersecurity‑related field. Candidates must demonstrate an understanding of legacy and modern programming standards, secure coding principles, and risk management methodologies. Within six (6) months of the assignment, the candidate must possess or obtain one of the following certifications: CySA+, CGRC (formerly CAP), Security+, CISSP, SSCP, or CSSLP. The candidate must be familiar with secure coding and cybersecurity practices. Additionally, the candidate must be able to obtain and maintain a Secret or Top‑Secret security clearance.

PREFERRED: A bachelor’s degree in Computer Science, Computer Engineering, Software Engineering, or Cybersecurity, and at least five (5) years of experience in related engineering or cybersecurity positions. Desired qualifications include hands‑on experience with IC/SCADA systems, vulnerability hunting, threat analysis, software reverse engineering, Ghidra, Binwalk, hardware debugging interfaces (e.g., JTAG, UART, I2C). Possession of one of the following certifications: CDP, CDE, CEH, CASE, GREM, or GICSP. Direct experience supporting USAF, military service, or military weapon systems is highly preferred. Must possess an active Secret or Top‑Secret security clearance.
