This role involves leading security architecture and design reviews for high-priority products, conducting threat modeling, and performing technical security assessments of complex applications, APIs, and distributed systems. You will identify material security risks, review application code, and evaluate authentication, authorization, and sensitive data flows. The position requires identifying recurring weaknesses to define reusable security requirements and secure design patterns. You will utilize AI-assisted security analysis and testing to validate security assumptions. Key requirements include expertise in application security fundamentals, cloud-native applications, and technical risk assessment. You must be able to influence architectural decisions and communicate complex risks to engineering and product leadership.

What you'll do

  • Lead security architecture and design reviews for high-priority products from early development through launch.
  • Conduct threat modeling and technical security assessments of complex applications, APIs, and distributed systems.
  • Evaluate authentication, authorization, trust boundaries, and sensitive data flows to identify potential vulnerabilities.
  • Review application code to investigate security weaknesses and validate that proposed fixes address underlying risks.
  • Assess security implications of new technologies, including AI-powered applications and agentic workflows.
  • Partner with engineering leadership to prioritize material security risks and track them through remediation.
  • Define reusable security requirements and secure design patterns to implement preventive controls.
  • Leverage AI-assisted security analysis and testing to improve security assessments and validate assumptions.

What we're looking for

  • 5+ years of experience in product or application security with expertise in secure architecture and technical risk assessment.
  • Experience leading security design reviews and threat modeling for complex applications, APIs, or distributed systems.
  • Deep understanding of authentication, authorization, trust boundaries, sensitive data protection, and common application security vulnerabilities.
  • Strong software engineering fundamentals, including the ability to read application code and analyze vulnerability paths.
  • Experience assessing security risks in cloud-native applications and understanding the security implications of system architecture.
  • Ability to communicate complex security risks and influence engineering and product leadership.
  • Experience securing AI-powered applications or agentic systems (preferred).
  • Experience with penetration testing, vulnerability research, or securing financial technology products (preferred).
