Remote position, only for professionals based in Argentina or Uruguay

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.





Qualifications & Requirements of the Position:

- 5+ years of experience as a Full Stack Engineer, Platform Engineer, or AI Engineer with ownership of production systems.

- Strong proficiency in JavaScript/TypeScript and modern frontend frameworks (React, Next.js, or equivalent).

- Backend development experience with Python, Java, or Node.js, including building secure, scalable APIs.
- Hands-on experience delivering AI/ML solutions into production environments.

- Solid understanding of identity and access management (IAM) concepts, including authentication, authorization, and identity lifecycle.

- Proven experience leading or contributing to SSO migrations using OAuth 2.0, OpenID Connect, and/or SAML.

- Experience with domain consolidation or identity unification initiatives across multiple applications or platforms.

- Demonstrated ability to improve developer experience (DevEx) through internal tooling, APIs, SDKs, or platform improvements.

- Experience working with cloud platforms (AWS, GCP, or Azure) and containerized environments (Docker, Kubernetes).

- Strong security mindset, including experience designing systems with privacy, compliance, and resilience in mind.

- Ability to collaborate cross-functionally and communicate complex technical concepts clearly.

Knowledge, Skills, and Abilities Required:

- Background in cybersecurity, fraud detection, trust & safety, or abuse prevention.

- Experience with graph-based ML, NLP for security signals, or time-series anomaly detection.

- Knowledge of adversarial ML, model evasion techniques, or secure model design.

- Experience building systems operating under strict latency or reliability constraints.

- Prior work in regulated or high-risk environments.

- Security certifications or relevant coursework (e.g., OSCP, CISSP concepts).

- Experience with SIEM/SOAR tools or security telemetry platforms.

- Publications, talks, or open-source contributions in AI, security, or related fields.
