Required Skills & Experience - 7+ years of engineering experience, including 7+ years in Application Security Engineering.
- 2+ years of hands-on threat modeling experience, including complex application and platform architectures.
- Experience building AI/LLM-enabled Application Security solutions for enterprise production environments.
- Strong automation and software engineering or scripting experience.
- Ability to analyze architectures, data flows, trust boundaries, APIs, controls, and security risks.
- Experience partnering with software engineering, architecture, cloud, and platform teams.
- Ability to remain a hands-on threat modeling practitioner while providing principal-level technical leadership.
Desired Skills & Experience - Deep knowledge of secure application architecture, STRIDE or similar threat modeling methodologies, OWASP risks, API security, authentication, authorization, cryptography, and data protection.
- Programming experience with technologies such as Java, .NET, Python, JavaScript/TypeScript, Node.js, or Go.
- Cloud and platform security experience across Azure, AWS, or GCP, including CI/CD and modern distributed or microservices architectures.
