About the role

Key responsibilities & impact

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.

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.
