At Ryz Labs we are looking for a Full Stack AI Engineer – BuilderEx to build intelligent, secure, and scalable identity experiences across our platforms. In this role, you will work end-to-end—from frontend UX to backend services and AI models—focusing on authentication, authorization, identity verification, fraud detection, and personalization.
This role combines full stack engineering, AI/ML integration, and identity architecture, with close collaboration across product, security, and platform teams to deliver privacy-first, highly reliable systems.

Essential Responsibilities:
Design, build, and maintain full-stack applications powering identity and access management (IAM) experiences.
Develop and integrate AI/ML models for identity use cases such as fraud detection, anomaly detection, risk-based authentication, and identity verification.
Lead and execute SSO migrations across products and platforms, consolidating authentication flows while minimizing user disruption.




Drive domain consolidation initiatives by unifying identity systems, services, and user data models across multiple platforms or brands.
Improve developer experience (DevEx) by building internal tools, SDKs, APIs, and documentation that simplify identity integrations.
Design and evolve secure, scalable APIs supporting authentication, authorization, and identity data services.
Partner closely with Security, Platform, and Product teams to implement and standardize protocols and patterns such as OAuth 2.0, OpenID Connect, SAML, JWT, and zero-trust architectures.
Ensure AI-powered identity systems are observable, explainable, and production-ready, with robust monitoring and feedback loops.
Balance security, performance, and usability while maintaining high standards for privacy and compliance.
Contribute to architectural decisions, technical design discussions, and code quality standards.
