Zero Trust Team Lead

As a Zero-Trust Offensive Security Lead, you will be at the forefront of validating and stress-testing the "never trust, always verify" security model across our customers' networks, systems, and applications. Your role is critical in proving the resilience of Zero-Trust architectures against advanced threats, ensuring that every user, device, and service is continuously authenticated, authorized, and monitored .

You will serve as the technical lead for penetration testing and threat emulation engagements - supervising your assessment team, interfacing directly with customers, and guiding them in strengthening least privilege, micro-segmentation, and continuous verification controls. Primary work will support the Department of Defense (Navy), with additional opportunities to lead commercial sector engagements.

This is more than a penetration testing role- it's about challenging the assumptions of trust in modern architectures and proving the effectiveness of Zero-Trust implementations in the most demanding environments. You won't just find vulnerabilities; you'll help organizations architect and validate security with the assumption of compromise at its core.

Key Responsibilities

• Lead and execute offensive security operations designed to validate Zero-Trust principles across internal, external, cloud, and hybrid environments.

• Simulate advanced adversary tactics to identify weaknesses in identity management, segmentation, and trust boundaries.

• Perform vulnerability analysis, exploitation, and custom test development to challenge authentication, authorization, and monitoring controls.

• Design and conduct scenario-based penetration tests and Purple Team exercises to measure detection and prevention capabilities against MITRE ATT&CK-mapped threats.

• Deliver detailed reports and executive briefings, prioritizing remediation strategies that advance the customer's Zero-Trust maturity.

• Collaborate with SOC and IR teams to ensure findings feed into continuous monitoring and adaptive policy enforcement.

• Perform reverse engineering or malware analysis to develop defensive measures tailored to endpoint and network trust validation requirements.

Required Qualifications

• Active DoD Top Secret clearance.
• Bachelor's degree in a related field or 10+ years of relevant IT or cybersecurity experience.

• 7 + years of direct experience in penetration testing, red teaming, and vulnerability assessments.

• Proven expertise applying Zero-Trust security concepts in offensive security engagements.

• Scripting skills in Python, Ruby, Lua/NSE, and PowerShell for automation and custom testing.

• Experience developing Rules of Engagement, policies, and operational plans aligned with Zero-Trust governance.

• Familiarity with SOC/IR workflows and integration into continuous verification processes.

• Active DoD 8570 IAT Level I I or greater, plus one or more of the following: OSCP, OSCE, OSWA, OSWE, GPEN, GXPN, GWAPT.

• Deep knowledge of vulnerabilities, attack vectors, and mitigations, especially those impacting identity, access control, and segmentation in Zero-Trust designs.

• Proficiency with offensive security tools such as Nmap, Kali Linux, Metasploit, Cobalt Strike, and Burp Suite.

Preferred Qualifications

• Experience in Red and Purple Team testing methodologies.

• Familiarity with MITRE ATT&CK and D3FEND frameworks.

• Experience emulating APT campaigns to test Zero-Trust enforcement.
