Responsibilities

• Lead Technical Strategy: Define the long-term vision for offensive security at Greenlight, moving beyond point-in-time testing to continuous security validation.
• Red Teaming & Adversary Simulation: Design and execute complex, multi-stage adversary simulations targeting our cloud infrastructure (AWS), mobile applications (iOS/Android), and internal corporate environments.
• Vulnerability Research: Conduct deep-dive research into high-risk areas of our ecosystem, identifying zero-day vulnerabilities or sophisticated logic flaws that automated tools miss.
• Pave the "Golden Path": Partner with DevOps and Engineering to build automated security guardrails and "self-healing" infrastructure that prevents common attack vectors from being introduced.
• Incident Response Support: Work closely with the Detection and Response team to improve our monitoring capabilities by performing "purple team" exercises to validate alert coverage.
• Mentorship: Act as a force multiplier by mentoring senior and mid-level engineers, fostering a culture of security-minded development across the entire R&D organization.

Requirements

• Expert-level Offensive Skills: 8+ years of experience in offensive security, red teaming, or penetration testing, with a proven track record of uncovering critical vulnerabilities in complex environments.
• Cloud Native Expertise: Deep understanding of AWS security architecture, including IAM bypass techniques, container escapes (Kubernetes), and serverless security.
• Application Security Depth: Experience with manual code review (Node.js, Python, or Go) and bypass techniques for modern web and mobile security controls.
• Automation Mindset: Ability to script in Python, Bash, or Go to automate exploitation chains or integrate security testing into CI/CD pipelines.
• Strategic Communication: The ability to translate complex technical risks into business impact for executive stakeholders while remaining a trusted peer to software engineers.
• Relevant Certifications (Optional but valued): OSCP/OSCE, GXPN, or equivalent demonstration of deep technical skill.
• An Ethical Hacker at Heart: You are curious, persistent, and think outside the box to find ways around traditional security controls.
• A Collaborative Partner: You believe that "breaking things" is only half the job; the real value is in helping the team build them back stronger.
• Owner Mindset: You take pride in your work and feel a deep sense of responsibility for the safety of our families and their finances.
