You think adversarially, understand modern application architectures, and can clearly articulate risk tradeoffs to engineering, product, and security leadership
• You are comfortable operating independently in ambiguous situations, influencing outcomes through credibility and collaboration rather than formal authority. You communicate clearly, mentor others naturally, and help elevate application security maturity across teams by embedding secure design principles into everyday engineering practices
• 6+ years of experience in application security or product security roles
• Demonstrated impact improving application security outcomes across multiple teams, systems, or business domains
• Deep experience securing web applications, APIs, distributed systems, WAFs, and customer identity platforms
• Strong understanding of authentication and identity protocols (OAuth2, OIDC, SAML, JWT, MFA)
• Proven ability to review system designs, data flows, and identify architectural security risks
• Solid understanding of cloud-native application architectures and CI/CD pipelines from an application risk perspective
• Experience designing or maintaining automated security tooling and pipelines (SAST, DAST, SCA, secrets detection)
• Proficiency in one or more modern programming languages

• Identify, assess, and clearly communicate application-centric security risks across application code, CI/CD pipelines, identity systems, and cloud environments
• Independently own and drive resolution of complex and ambiguous application security challenges with broad organizational impact
• Apply threat modeling, attack-path analysis, and adversarial thinking to inform defensive improvements and strengthen application resilience
• Contribute technically to broader security programs by shaping standards, best practices, secure patterns, and technical guidance
• Support security incidents and targeted threat-hunting efforts by providing application security expertise, root-cause analysis, and remediation guidance
• Design, improve, and help operationalize automated security tooling and pipelines (e.g., SAST, DAST, SCA, secrets detection)
• Mentor engineers and security partners across teams, acting as a force multiplier to improve secure design and decision-making at scale
• Communicate risks, recommendations, and standards clearly to senior engineers and security leadership to influence technical direction
