Cyber Offensive Security Senior Associate

As a Senior Offensive Security Consultant on our Cyber Defense team, you will get the opportunity to lead adversarial testing engagements for clients across a range of industries. In this role, you will simulate real-world adversaries to identify exploitable weaknesses, validate detection and response capabilities, and help clients measurably strengthen their security posture. This is a hands-on technical role with significant client interaction and ideal for someone who thrives on solving complex problems and communicating impact to both technical teams and executive stakeholders.

From day one, you’ll be empowered by the greater Cyber & Risk team to help clients make the moves that will help them achieve their vision and help you achieve more, confidently.

Your day-to-day may include

• Penetration Testing: Plan and execute network, application, API, and cloud penetration tests, from scoping through exploitation, post-exploitation, and reporting.
• Adversary Emulations: Design and run, threat-informed attack simulations to validate the effectiveness of client security controls and detection coverage.
• Assume-Breach: Conduct assume-breach engagements, collaborating with defensive teams to test detection, response, and containment capabilities.
• AI Red Teaming: Perform adversarial testing of AI/ML systems and LLM-enabled applications, including prompt injection, model manipulation, data exfiltration, and abuse-case testing.
• Threat Emulation: Emulate the tactics, techniques, and procedures (TTPs) of relevant threat actors, mapping activity to frameworks such as MITRE ATT&CK.
• Reporting & Communication: Produce clear, high-quality deliverables that translate technical findings into prioritized, business-relevant remediation guidance; present results to technical staff, management, and executive/board audiences.
• Client Advisory: Serve as a trusted technical advisor, helping clients understand risk, prioritize remediation, and mature their security programs.
• Practice Development: Contribute to methodology development, tooling, automation, and the mentoring of junior team members.
