Key Responsibilities:
● API Logic Security: Hunt for Business Logic vulnerabilities (BOLA/IDOR, Mass
Assignment) that traditional firewalls miss.

implementations to ensure users can only access their own data.
● Attack Simulation: Script automated attacks against the API Gateway to test rate limiting
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).

Staying safe while you apply

Never pay to apply, interview or accept an offer. ROLIVA never asks you for payment to apply to a job.
Apply only through the official “Apply on the employer’s site” button, on the employer’s own site, and check that a recruiter’s email uses that employer’s own domain rather than a free email address.
Be cautious of an offer made with no real interview, or pressure to decide quickly or share financial details early.
