Position Overview:
We are inviting a hands-on Senior Identity Engineer to own the design, development, and operations of our Auth0-based Customer Identity and Access Management (CIAM) platform, serving 30 million customer accounts.
This is not an administrative role. It is a Backend Engineering & Security role. You will bridge the gap between our core enterprise systems (WCS) and modern API architectures. You will deliver hands-onNode.js development for custom authentication logic while ensuring operational excellence through GitLab CI/CD pipelines and forensic troubleshooting.
ShyftLabs is a growing data product company that was founded in early 2020 and works primarily with Fortune 500 companies. We deliver digital solutions built to help accelerate the growth of businesses in various industries, by focusing on creating value through innovation.
Job Responsibilities: :
• 1. Auth0 Architecture & Backend Development (Node.js):
• Design and Code Auth0 Actions: Write efficient, asynchronous Node.js scripts to customize authentication flows. You must handle strict timeouts, race conditions, and external API dependencies efficiently.
• Manage Auth0 Forms: Develop and maintain the Universal Login experience using Auth0 Forms to ensure a seamless User Experience (UX).
• Secure API Integrations: Develop and maintain robust API integrations between Auth0 and our core e-commerce backend (WCS) and third-party services.
• 2. Forensic Troubleshooting & Operations:
• Deep-Dive Analysis: Actively monitor and analyze authentication logs using Auth0 Log Streams and Datadog. You will be responsible for diagnosing root causes of login failures, anomalies, and performance bottlenecks.
• Incident Response: Participate in the support rotation for the CIAM platform, ensuring rapid incident response and system resilience for our critical login infrastructure.
• 3. DevSecOps & Pipeline Management:
• CI/CD Management: Maintain and optimize our GitLab CI/CD pipelines for deploying Auth0 configurations, ensuring a secure, automated, and audit-ready release process across environments (Dev, Stage, Prod).
• Infrastructure as Code (IaC): Apply IaC principles to manage Identity resources, preventing configuration drift and ensuring reproducibility.
Basic Qualification::
• Deep Auth0 Expertise: 3+ years of specific experience with Auth0 (Actions, Management API, Universal Login) in a high-volume environment.
• Strong Backend Development: Proficiency in Node.js. You must be comfortable writing complex logic for API consumption, data transformation, and error handling..
• Observability Mastery: Proven experience using tools like Datadog, Splunk, or extensive log analysis to debug complex identity issues. You should be able to trace a user's session across systems to find why a login failed.
• CI/CD: Experience managing deployments via GitLab pipelines (or similar CI/CD tools) rather than manual Click-Ops configuration.
• API Security Standards: Deep understanding of OIDC, OAuth 2.0, JWT structure, and secure session practices.
Preferred Qualifications::
• Experience integrating with enterprise e-commerce platforms.
• Familiarity with Terraform for infrastructure management.
• Background in Security Engineering with on-call/rotation experience.
