- Evaluate authentication, authorization, trust boundaries, sensitive data flows, and business logic to identify potential vulnerabilities and abuse cases.

- Review application code, investigate security weaknesses, and validate that proposed fixes address the underlying risks.

- Assess security implications of new technologies and product capabilities, including AI-powered applications and agentic workflows.

- Partner with engineering leadership to prioritize material security risks, agree on mitigations, and track them through remediation or approved risk acceptance.

- Identify recurring security weaknesses, define reusable security requirements and secure design patterns, and partner with engineering teams to implement preventive controls.

- Leverage AI-assisted security analysis and testing to continuously improve security assessments and validate important security assumptions.

**Requirements:**

- 5+ years of experience in product or application security, with strong expertise in secure architecture, application security fundamentals, 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, analyze vulnerability paths, and evaluate security fixes.

- Experience assessing security risks in cloud-native applications and understanding the security implications of system architecture and implementation decisions.

- Ability to communicate complex security risks, recommend practical mitigations, and influence engineering and product leadership.

- Ability to operate independently in ambiguous environments and collaborate effectively across teams.

**Nice to Have:**

- Experience securing AI-powered applications or agentic systems.

- Experience with penetration testing, vulnerability research, or security testing of complex business logic.

- Experience securing financial technology products or systems handling sensitive or regulated data.
