Join a dynamic front-end engineering team focused on building secure, seamless identity experiences across web applications. This role is ideal for someone who enjoys turning complex authentication and authorization requirements into reusable, user-friendly solutions that support enterprise-scale applications.

Responsibilities

• Integrate a third-party identity platform into custom web applications using SDKs, APIs, hosted components, and authentication services.
• Build reusable front-end components, hooks, and libraries that can be adopted across multiple applications.
• Implement secure authentication and authorization flows using modern standards such as OAuth 2.0, OpenID Connect, SAML, JWTs, and PKCE.
• Connect identity workflows with application routing, state management, backend services, and session handling patterns.
• Ensure user experiences meet requirements for usability, responsiveness, accessibility, performance, branding, and internationalization.
• Partner with security, architecture, product, UX, and vendor teams to translate requirements into production-ready solutions.
• Support secure token handling, session controls, error management, and protection against common web application vulnerabilities.
• Create and maintain automated tests for identity-related workflows using modern testing tools.
• Troubleshoot authentication issues across browser, application, API, network, and vendor-platform boundaries.
• Contribute to logging, telemetry, and monitoring efforts to help measure authentication performance and user experience.
• Take part in code reviews, architecture discussions, sprint planning, backlog refinement, and production readiness activities.
• Document implementation patterns and help onboard other application teams to shared identity solutions.

Skills

• Professional front-end development experience, with hands-on work in React and TypeScript.
• Experience integrating web applications with RESTful APIs, SDKs, and backend services.
• Working knowledge of authentication and authorization concepts, including access tokens, ID tokens, refresh tokens, cookies, and browser sessions.
• Experience implementing secure sign-in and access flows in single-page or server-rendered applications.
• Strong understanding of browser security concepts such as CORS, CSP, XSS, CSRF, secure cookies, and storage risks.
• Experience with automated testing tools such as Jest, React Testing Library, Cypress, Playwright, or similar.
• Familiarity with source control, pull requests, CI/CD workflows, and automated quality checks.
• Ability to investigate issues using browser tools, logs, API traces, and monitoring platforms.
• Clear communication skills and the ability to work effectively with technical and non-technical partners.

Preferred Skills

• Direct experience with commercial identity platforms such as Ping Identity, Okta/Auth0, Microsoft Entra External ID, ForgeRock, Transmit Security, or similar solutions.
• Background in customer identity, workforce identity, or business-to-business identity environments.
• Experience building shared component libraries, design systems, or reusable platform capabilities.
• Knowledge of role-based and attribute-based access control approaches.
• Familiarity with identity federation, social login, step-up authentication, adaptive authentication, or risk-based authentication.
• Exposure to Next.js, Node.js, GraphQL, micro-frontends, or module federation.
• Experience working in cloud-based or cloud-native application environments.
• Familiarity with observability tools such as Splunk, Datadog, Dynatrace, New Relic, or Grafana.
• Experience in regulated, high-volume, retail, consumer, or enterprise environments.
