About the Job

Requirements

  • At least 4 years of experience in offensive security, red team operations, penetration testing, application security, cloud security, cyber defense, or related security assessment roles.
  • Hands-on experience supporting security assessments, adversary emulation, control validation, vulnerability analysis, or threat-informed testing.
  • Working knowledge of common attack techniques across Windows, Linux, Active Directory, web applications, APIs, cloud platforms, and identity systems.
  • Ability to write or modify scripts and tools using languages such as Python, PowerShell, Bash, JavaScript, or similar.
  • Familiarity with offensive security tools, vulnerability validation, command-and-control concepts, detection engineering concepts, and MITRE ATT&CK mapping.
  • Understanding of AI security risks such as prompt injection, excessive agency, insecure tool use, sensitive data exposure, insecure plugins, model abuse, and AI-enabled social engineering.

Responsibilities

  • Support the planning and execution of Red Team, Purple Team, adversary simulation, and control validation engagements.
  • Assist with target research, scope development, rules of engagement, infrastructure preparation, and operational documentation.
  • Coordinate with defensive, engineering, risk, and business stakeholders to ensure engagements are well-structured and findings are actionable.
  • Perform hands-on offensive security testing across network, endpoint, identity, application, cloud, and selected physical attack surfaces.
  • Execute techniques such as reconnaissance, initial access validation, privilege escalation, lateral movement, persistence simulation, and control evasion in approved environments.
  • Develop, modify, and safely use scripts, payloads, tooling, and tradecraft to support realistic adversary emulation.
  • Support adversarial testing of AI and large language model systems, including prompt injection, data leakage, tool misuse, model behavior abuse, and guardrail bypass scenarios.
  • Analyze AI-enabled applications, copilots, automation workflows, agents, plugins, APIs, and data integrations for security and abuse risks.
  • Document AI security observations in clear business and technical terms, including risk impact, exploitability, control gaps, and recommended remediation.
  • Use AI-assisted analysis responsibly to accelerate research, data review, reporting, detection mapping, and test-case development.
  • Track emerging AI threats, attacker use of AI, and relevant industry guidance to inform Red Team scenarios and validation priorities.
  • Drive research into real-world threat actor tactics, techniques, and procedures and emerging AI-enabled attack techniques.
  • Sponsor development of red team tools, scripts, and repeatable methodologies to increase realism, scale, and efficiency.
  • Establish standards for tooling governance, safe use, and audit readiness.
  • Prepare engagement notes, evidence packages, attack narratives, findings, remediation guidance, and executive-ready summaries.
  • Map observations to relevant frameworks, controls, detections, and business risk themes where appropriate.
  • Partner with blue team, cyber defense, engineering, governance, and application teams to validate remediation and improve control effectiveness.

Desired Qualifications

  • Exposure to AI security, large language model testing, AI governance, data security, machine learning workflows, or secure use of AI-assisted tools.
  • A bachelor's degree in Cybersecurity, Computer Science, Information Technology, Engineering, Data Science, or equivalent experience.
  • Security certifications such as OSCP, GPEN, GWAPT, GCIH, GCIA, GSEC, CISSP, or similar.
  • Familiarity with regulatory, risk, or control frameworks such as NIST, FFIEC, GLBA, SOX, PCI, or internal control standards.
