Role Overview
Amadeus operates an Enterprise Identity and Access Management (IAM) system in the travel technology industry, serving thousands of employees, partners, and enterprise customers across the globe. As digital identity becomes increasingly central to platform security and user experience, the need to modernize authentication mechanisms is critical.

Traditional password-based authentication presents growing challenges in terms of usability, scalability, and vulnerability to attacks. In response, WebAuthn, the W3C standard for passwordless authentication, offers a robust alternative—leveraging biometrics, hardware tokens, and device-bound credentials to deliver secure, phishing-resistant login experiences.

This internship is embedded within the IAM Engineering team at Amadeus and focuses on designing and integrating WebAuthn-based authentication into existing IAM workflows. The goal is to enhance security posture while improving user experience for customer and internal users accessing Amadeus platforms.

Key Responsibilities

• Analyze current IAM authentication flows and identify integration points for WebAuthn in existing protocols (OAuth2, OpenID Connect).
• Design and prototype passwordless login experiences for internal and external users in the existing Entreprise IAM.
• Document technical decisions and integration patterns.

Tasks Involved

• Study state of the art of password less authentication and existing libraries.
• Build and test WebAuthn registration and authentication flows in the current Entreprise IAM architecture.
• Showcase the prototype to stakeholders and to developers who could use this solution

Technical Skills
Programming Languages and technologies:

• C++, Java, Angular
• Docker, kubernetes, openshift

Knowledge of RESTful APIs

Familiarity with OAuth2 and OpenID Connect protocols is a plus.
