Java Full Stack Engineer II - WFH

Key Responsibilities: Design, develop, enhance, test, and maintain secure enterprise web applications, including responsive front-end components, back-end services, APIs, and business logic throughout the Software Development Life Cycle (SDLC).Develop intuitive, responsive, accessible, and secure user interfaces using modern front-end technologies and frameworks. Implement identity-verification screens, user enrollment and verification workflows, form validation, dynamic response handling, error messaging, and exception-management interfaces in accordance with accessibility and usability standards. Design, develop, configure, and integrate secure back-end components and RESTful services that consume Experian or comparable identity-proofing APIs. Implement identity-verification workflows, secure data exchange, risk-signal processing, decision-response handling, exception management, and integrations with existing enterprise applications and digital service platforms. Develop secure API integrations using REST, JSON, API gateways, OAuth 2.0, OpenID Connect (OIDC), mutual TLS (mTLS), certificates, token-based authentication, secrets management, and least-privilege access controls. Secure communication between front-end applications, back-end services, identity-verification platforms, and enterprise systems. Apply secure coding practices and identity-proofing principles aligned with NIST SP 800-63 guidelines. Implement encryption, data masking, Personally Identifiable Information (PII) protection, secure data handling, retention controls, fraud mitigation, audit logging, and transaction traceability across application and integration layers. Develop and execute unit, integration, API, functional, regression, accessibility, performance, and security tests across front-end and back-end components. Diagnose and resolve UI defects, API integration failures, authentication issues, identity-verification errors, performance bottlenecks, and security vulnerabilities through root-cause analysis and remediation. Implement secure software delivery practices using source control, peer code reviews, automated testing, CI/CD pipelines, configuration management, and controlled deployments. Support vulnerability remediation, application monitoring, centralized logging, Security Information and Event Management (SIEM) integration, release validation, incident troubleshooting, and documented rollback procedures. Maintain application designs, UI specifications, API integration documentation, identity-verification workflow configurations, deployment procedures, operational runbooks, and reusable implementation standards. Collaborate with solution architects, cybersecurity teams, business stakeholders, QA engineers, infrastructure teams, and Experian vendor support personnel to support implementation, operational readiness, and knowledge transfer.

Required Qualifications: 5+ years of professional software development and integration experience across the full SDLC, including enterprise web applications, responsive front-end interfaces, secure back-end services, and complex system integrations. Strong proficiency in HTML5, CSS3, JavaScript/TypeScript, and modern UI frameworks such as Angular, React, or comparable technologies. Experience developing reusable UI components, responsive web applications, client-side validation, asynchronous API interactions, accessible interfaces, and secure user-facing workflows. Hands-on experience developing server-side application components, RESTful APIs, service-layer business logic, and secure integration services using enterprise back-end technologies. Strong understanding of JSON, request and response processing, API error handling, data validation, exception management, and integration design patterns. Experience integrating Experian or comparable identity-verification services into enterprise applications, including identity-proofing API configuration and consumption, verification workflows, risk signals, decision responses, exception handling, and vendor-supported integration troubleshooting. Proficiency with OAuth 2.0, OpenID Connect, mutual TLS, API gateways, certificates, token management, secrets management, secure communication protocols, and least-privilege access controls. Strong knowledge of secure coding practices, NIST SP 800-63 identity-proofing concepts, encryption, PII protection, data masking, privacy controls, audit logging, secure data retention, fraud mitigation, and auditable transaction tracking. Experience performing unit, integration, API, regression, accessibility, performance, and security testing. Ability to troubleshoot application defects, integration failures, authentication issues, and security vulnerabilities through root-cause analysis. Knowledge of application monitoring, centralized logging, and SIEM integration. Experience with Git or comparable source control systems, peer code reviews, automated testing, CI/CD pipelines, configuration management, vulnerability remediation, controlled deployments, and rollback procedures. Ability to prepare API specifications, technical designs, configuration documentation, operational runbooks, and knowledge-transfer materials.

Preferred Qualifications: Experience delivering enterprise or public-sector identity-verification, digital identity, cybersecurity, or application modernization initiatives. Hands-on experience configuring Experian identity-proofing services, risk-based decision workflows, verification responses, and exception-handling processes. Experience developing and consuming secure RESTful APIs and integrating third-party identity-verification services with modern web applications. Familiarity with modern application architecture, API gateway configurations, distributed services, and enterprise integration patterns. Experience implementing accessible digital services aligned with WCAG standards and applicable enterprise accessibility requirements. Experience with automated UI testing, API testing frameworks, vulnerability scanning, application performance monitoring, and DevSecOps practices. Experience supporting production applications, managing integration incidents, and coordinating technical issue resolution with external service providers. Strong analytical, problem-solving, technical documentation, communication, and cross-functional collaboration skills. Employment TypeFull-TimeWork Arrangement Remote
