The ideal candidate is a highly skilled offensive security professional with extensive experience planning, leading, and executing advanced penetration testing and red team operations across complex federal IT environments. This individual will serve as the technical lead for SBA's penetration testing program, providing expert guidance on adversary simulation, vulnerability exploitation, and security control validation to help the agency identify and remediate security weaknesses before they can be exploited by real-world adversaries.

The Senior Lead Penetration Tester will serve as the primary technical lead for all penetration testing and offensive security activities supporting SBA's cybersecurity program, overseeing the full lifecycle of penetration testing engagements, red team operations, and adversary simulation exercises across SBA's enterprise environment. This individual will bring deep technical expertise, strong leadership capabilities, and a comprehensive understanding of adversary TTPs to drive a high-quality, mission-focused penetration testing program that meaningfully strengthens SBA's security posture.

Principal responsibilities will include but are not limited to:

•  Lead the end-to-end planning, scoping, coordination, execution, and reporting of advanced penetration testing engagements across all components of SBA's enterprise IT environment, including network infrastructure, web applications, mobile applications, APIs, cloud environments, and supporting systems and services.
• Design and execute sophisticated red team operations and adversary simulation exercises that realistically emulate the tactics, techniques, and procedures (TTPs) of advanced persistent threat (APT) actors, nation-state adversaries, and other sophisticated threat actors known to target federal civilian agencies.
• Conduct advanced exploitation of vulnerabilities identified during penetration testing engagements, including privilege escalation, lateral movement, persistence establishment, credential harvesting, and data exfiltration, to accurately demonstrate the real-world impact and exploitability of identified security weaknesses.
• Develop and maintain a comprehensive, documented penetration testing methodology, program charter, and rules of engagement (ROE) for SBA's penetration testing program, ensuring alignment with industry best practices and federal security requirements including NIST SP 800-115 and applicable CISA guidance.
•  Produce detailed, high-quality penetration test reports and executive-level briefings documenting engagement scope, methodologies, technical findings, exploitation evidence, risk ratings, attack narratives, and prioritized, actionable remediation recommendations tailored to both technical and non-technical SBA audiences.
• Collaborate with SBA security leadership, the Cybersecurity Architect, SOC teams, and system owners to communicate penetration testing findings, validate remediation efforts through retesting activities, and provide expert guidance on the prioritization and resolution of identified vulnerabilities and security control gaps.
• Conduct web application penetration testing in accordance with industry frameworks and standards including the OWASP Testing Guide and OWASP API Security Top 10, identifying and exploiting vulnerabilities including injection flaws, broken authentication, cross-site scripting (XSS), insecure direct object references (IDOR), business logic flaws, and other advanced application security vulnerabilities.
• Perform cloud penetration testing and security configuration assessments across AWS, Azure, and/or GCP environments, evaluating the security of cloud service configurations, IAM policies, storage services, network controls, serverless functions, and container environments.
• Develop and utilize custom exploitation tools, offensive scripts, and proof-of-concept (PoC) code to demonstrate the exploitability of identified vulnerabilities and support penetration testing operations in scenarios where commercial tools are insufficient or inappropriate.
• Lead social engineering assessments, including phishing and spear-phishing campaigns, vishing exercises, and physical penetration testing activities, to evaluate SBA's human and physical security controls and the effectiveness of the agency's security awareness program.
• Support and validate vulnerability management activities by providing expert-level analysis of vulnerability scan results, assessing real-world exploitability and risk in the context of SBA's environment, and advising on remediation prioritization strategies based on actual exploitation risk.
• Stay current with the latest offensive security research, vulnerability disclosures, exploit development techniques, and adversary TTPs, continuously applying new knowledge to improve the quality, realism, and effectiveness of SBA's penetration testing program.
• Mentor and provide senior technical leadership to junior and mid-level penetration testers, fostering professional growth, knowledge transfer, and the continuous development of the offensive security team's technical capabilities.
• Ensure all penetration testing and offensive security activities are conducted in strict compliance with SBA's approved rules of engagement, applicable federal laws and regulations, and the ethical standards governing offensive security research and testing.
• Coordinate and lead purple team exercises in collaboration with SBA's blue team, SOC, and incident response teams, designing realistic attack scenarios to validate detection and response capabilities and drive measurable improvements in SBA's defensive posture.
