Principal Digital Security Architect

Key Responsibilities 1. API & Ecosystem Architecture ● The API Fortress: Architect the security layer for our API Gateway (e.g., Kong, Apigee, AWS Gateway). Define global policies for Rate Limiting, Throttling, and Authorization (preventing BOLA/IDOR attacks). ● Supply Chain Security: Design secure integration patterns for our 3rd party partners (Fintechs, Credit Bureaus, Payment Processors). Ensure their insecurities do not become our breaches. ● Microservices Mesh: Define how our internal services trust each other. Move from "Network Trust" to "Cryptographic Trust" using mTLS and Service-to-Service authentication. 2. Identity & Access Management (CIAM) ● Identity Strategy: Own the architecture for Customer Identity (CIAM). Design flows for Biometric Binding, Adaptive MFA, and Step-Up Authentication for high-value transactions. ● Token Lifecycle: Define the standards for OAuth 2.0 and OpenID Connect (OIDC). Ensure we are using Financial-grade API (FAPI) standards for token issuance, revocation, and storage. 3. Secure Development Lifecycle (SDLC) ● Threat Modeling: Lead "Whiteboard Hacking" sessions with product owners. Identify business logic flaws (e.g., race conditions in ledgers, bypassable KYC steps) before a single line of code is written. ● Paved Roads: Work with DevOps to architect secure-by-default libraries. (Example: Create a standard "Encryption Wrapper" library that all developers must use, so they don't invent their own crypto). 4. Data Privacy & Cryptography ● Data Defense: Define the architecture for Field-Level Encryption (FLE) in the database for PII and Banking Secrets. ● Privacy Engineering: Architect systems that support "Right to be Forgotten" (GDPR/CCPA) without breaking the immutability of the financial ledger. Strategic Deliverables ● Identity Patterns: Deliver new security design patterns and components for authentication, authorization, SSO, MFA, and Partner security to ensure seamless and secure user access. ● Mobile & Edge: Deliver new security design patterns and components for Mobile security, ensuring consistency between iOS, Android, and the backend. ● Modern Tech Stack: Deliver API, container, cloud, and AI security design patterns to support the bank's move toward intelligent, cloud-native infrastructure. What We Are Looking For 1. The Background ● 8+ Years Experience: A mix of Software Engineering and Security Architecture. ● Ex-Developer: You must be able to read code (Java, Kotlin, React or Node.js, ). ● Banking/Fintech Experience: Strong preference for candidates who have secured payment gateways, ledgers, or wallets. 2. The Technical Skills ● API Security: Deep mastery of REST and GraphQL security. ● Auth Protocols: You can draw the OAuth 2.0 Authorization Code Flow with PKCE from memory. You understand JWT signing and JWKS key rotation. ● Mobile Security: Understanding of how mobile apps store secrets (KeyStore/Keychain) and how to prevent API abuse from emulators/bots. 3. The Mindset ● Business Aligned: You understand that a bank exists to process transactions. You design security that reduces risk without destroying the User Experience (UX). ● Pragmatic: You know when to demand a "Blocker" fix and when to accept a "Risk Acceptance" waiver.
