• Hands-on experience architecting and implementing security solutions and processes in production environments, enabling engineering teams to build and ship securely at scale.
• Expert-level knowledge of web and mobile application security, including OWASP Top 10, API security, and mobile threat vectors (iOS and Android).
• Deep hands-on experience with the full AppSec toolchain: SAST, DAST, IAST, SCA, secrets scanning, and runtime protection.

• Experience leading or heavily influencing the security architecture of distributed, microservices-based systems.

• Familiarity with security tools including Burp Suite, or Kali Linux.

Responsibilities

• Define and lead the long-term product security strategy, roadmap, and vision in alignment with company goals, risk appetite, and regulatory requirements.
• Serve as the internal authority on application and product security, providing expert guidance to engineering, product, and executive leadership.
• Drive a company-wide culture of security ownership embedding security thinking deeply into the habits of every engineering team.

• Lead the design and enforcement of secure development standards across web, mobile, and cloud including secure coding guidelines, IaC policies, and API security frameworks.
• Identify and drive resolution of systemic, high-impact vulnerabilities and architectural security gaps across Greenlight's platform.
• Lead and mature Greenlight's penetration testing program, both through internal efforts and external vendor partnerships.
