• Collaborate with application teams to ensure secure and frictionless authentication flows.
Customization & Extensibility
• Develop custom Auth0 Actions, Rules, and Hooks using Node.js to implement complex business logic.
• Customize authentication pipelines, login pages, branding, and user journeys.
User Migration & Identity Management
• Design and execute silent migration strategies to move users from legacy identity stores to Auth0 without disrupting login experiences.
• Configure and maintain Role-Based Access Control (RBAC), permissions, and user roles.
• Manage identity providers including social (Google, Facebook), enterprise (ADFS, Azure AD), and database connections.
Automation & CI/CD Enablement
• Use the Auth0 Management API, Terraform, and infrastructure-as-code tools to automate tenant configuration.
• Implement CI/CD pipelines for managing and deploying Auth0 configurations across environments.
• Maintain documentation, versioning, and governance of identity configurations.
Security & Compliance
• Ensure adherence to application security best practices including secure token handling, session management, and PKCE flows.
• Collaborate with security teams to perform audits, penetration testing, and compliance checks.
• Monitor and respond to authentication-related issues, anomalies, and security incidents.

• Hands-on knowledge of containerized environments (Docker, Kubernetes).
• Strong understanding of Terraform or equivalent IaC tools.
Preferred Qualifications
• Experience with CIAM platforms (Okta, Azure AD B2C, ForgeRock) is a strong advantage.
• Knowledge of customer-facing identity workflows, self-service portals, or B2C authentication flows.
• Exposure to microservices, API gateways, and distributed systems.
• Auth0 Certifications (if applicable).
Soft Skills
• Strong problem-solving and debugging abilities.
• Excellent communication and ability to work with cross-functional teams.
• Attention to detail with a strong focus on security and user experience.
• Ability to work in agile teams and fast-paced environments.
