Key Responsibilities:

and fraud detection rules.
● Gateway Hardening: Work with the Platform team to configure the API Gateway (Kong,
or Azure API Gateway) for maximum security.
● Auth & Partner Integration: Deliver new security design patterns and components for
authentication, authorization, SSO, MFA, and Partner security. Standardize how we
consume external APIs (Open Banking) and how we secure our own exposed endpoints.
Technical Requirements:
● Strong scripting skills (Python) to automate API attacks.
● Expertise in REST and GraphQL security.
● Deep knowledge of OAuth 2.0 and OpenID Connect (OIDC) flows.
● Experience with API Security tools (Postman, Burp Suite, 42Crunch).
