Your Role

• Integrate security seamlessly into the Software Development Lifecycle (SDLC) and DevSecOps pipelines by automating security gates (SAST, DAST, SCA, and container scanning).
• Conduct thorough threat modeling and architectural security reviews for complex applications, APIs, and microservices prior to deployment.
• Perform deep-dive manual and automated secure code reviews across various codebases to identify logic flaws and subtle implementation vulnerabilities.
• Build and maintain "secure-by-default" internal libraries, frameworks, and developer tools to systematically eliminate entire classes of vulnerabilities.
• Take ownership of the application vulnerability lifecycle, including triaging, validating, and prioritizing vulnerabilities originating from internal testing, penetration tests, and external bug bounty programs.
• Act as a strategic partner to product and engineering teams, providing pragmatic mitigation guidance that balances product velocity with security assurance.
• Design and deliver modern, hands-on secure coding training and security awareness initiatives for engineering teams (e.g., addressing OWASP Top 10, LLM/AI security risks).
• Support incident response and detection teams during application-level security incidents or potential data breaches, leading post-mortem analysis for software flaws.
• Ensure application security controls remain fully compliant with relevant financial data protection regulations, fintech standards, and internal tech policies.
• Owners of this function make sure that they follow the defined Policies & Procedures for the institution (which includes explicit processes defined for Tech, which are properly defined in the respective confluence spaces).
• Take ownership of the tech responsibilities as described in our Change Management Policies.
