What You'll Do:
The Adversarial Red Team Lead Associate Principal provides professional input to complex Red Team assignments and projects, strengthening OCC's security posture by independently conducting covert black-box and occasional white-box assessments across network, web application, cloud, mobile, physical, and social engineering domains, while coordinating with Security and IT teams to address and retest remediated findings. This individual works independently and reviews or guides the work of more junior Red Team professionals, enhancing the knowledge and skill base of the organization. Ideal candidates will bring 7+ years of deep expertise in areas such as OSINT, penetration testing, C2 infrastructure development, evasion techniques, and custom scripting, along with strong communication skills and a commitment to staying ahead of emerging threats. All team members are held to the highest standards of ethics, integrity, and accountability, and are expected to foster a collaborative, bar-raising dynamic with OCC's defensive security teams.
Primary Duties and Responsibilities:
