About the Role
We are looking for an experienced UX/UI Developer with a background in authentication and identity workflows to join a large, complex enterprise organization on a contract basis. You will be part of a team building a next-generation, centralized authentication platform from the ground up, owning all user-facing login and identity flows across web, Android, and iOS. This role is well-suited for someone accustomed to the governance and change management demands of a large global organization, and who understands the unique UX and security requirements of authentication surfaces. Experience in banking/financial services or other highly regulated industries is a big plus.
Key Responsibilities
•    Design and build user-facing authentication components including login pages, multi-factor authentication flows, and account recovery experiences across web, Android, and iOS
•    Develop and maintain SDKs and UI libraries that integrate with underlying identity vendor services (Transmit, Ping, Arcus Labs, ThreatMetrix, and others)
•    Contribute to the identity Abstraction Layer, a vendor-agnostic library that decouples application teams from specific identity vendor SDKs
•    Collaborate with identity architects, backend API teams, and security engineers to ensure UI implementations align with authentication protocols and security requirements
•    Implement passkey and passwordless flows using FIDO2/WebAuthn standards
•    Build with forward compatibility in mind to support credential consolidation across multiple products and business lines over time
•    Maintain documentation for components, integration guides, and change requests in alignment with enterprise change management policies
•    Support testing, accessibility compliance, and performance optimization across all platforms
Required Qualifications
•    4+ years of experience in front-end or mobile UI development
•    Proficiency in React for web development; experience with React Native, native Android (Kotlin/Java), or native iOS (Swift) for mobile
•    Hands-on experience building or integrating with authentication flows: login, MFA, SSO, OAuth 2.0 / OIDC, or SAML
•    Familiarity with identity or authentication SDKs (any vendor: Ping, Transmit, Okta, ForgeRock, Auth0, or similar)
•    Understanding of security principles as they apply to UI: token handling, session management, secure storage on mobile
•    Experience working within large, complex enterprise environments at Fortune 150 scale or equivalent; exposure to regulated industries (financial services, healthcare, government) is a plus
•    Ability to work independently and manage deliverables with limited day-to-day supervision
Preferred Qualifications
•    Experience with passkeys or FIDO2/WebAuthn implementations
•    Familiarity with Transmit Security or Ping Identity products
•    Experience building shared UI component libraries or SDK wrapper layers
•    Exposure to centralized authentication or single sign-on architecture patterns
•    Familiarity with WCAG accessibility standards
•    Prior work in financial services, online banking, or other high-stakes consumer-facing digital products is a plus
Contractor Requirements
•    Must be based in the United States and authorized to work without sponsorship
•    Must be able to pass a background check
