Identity Platform Integration Engineer

Responsibilities

Peraton is seeking an Identity Platform Integration Engineer to support the Department of Defense's next‑generation enterprise Identity, Credential, and Access Management (ICAM) platform that is replacing DS Logon and providing secure authentication services for millions of Service Members, Veterans, Family Members, and Beneficiaries. The Alternative Multi‑factor Authentication Support Services (AMASS) Program provides secure, scalable identity and access management services across the Department of Defense, enabling authentication, authorization, and digital identity interoperability for high visibility DoD systems.

In this role you will specialize in identity integration, secure authentication services, and API development, not general‑purpose backend application development. The ideal candidate has hands‑on experience with modern IAM/ICAM standards, secure API design, enterprise identity services, and mission‑critical service integration within Federal environments.

This is a 100% remote role.

• Design, develop, and integrate RESTful APIs supporting identity workflows and partner application authentication.
• Implement OAuth 2.0, OpenID Connect (OIDC), PKCE, and secure token management patterns.
• Build secure API authentication and authorization services using JWT, access tokens, and refresh tokens.
• Integrate backend services with the Okta Identity Engine (OIE), Okta Embedded SDK, and DoD enterprise IAM solutions.
• Implement identity service integrations with authoritative identity repositories and enterprise data sources.
• Develop secure backend web services using Java, Spring Boot, .NET, or equivalent technologies.
• Support API gateway configurations, microservices architecture, and service orchestration patterns.
• Implement JSON/XML data exchange models and develop API contracts supporting partner application consumption.
• Apply enterprise integration patterns and asynchronous messaging (queues, events, service buses).
• Design authentication workflow orchestration and session management services.
• Develop backend services supporting mobile authentication for native iOS and Android applications.
• Apply advanced API security practices, including OWASP API Security Top 10, mTLS, and certificate‑based authentication.
• Implement secure database integration and data access patterns.

• Develop reusable identity services supporting multiple Partner Applications.
• Implement API Gateway integrations.
• Implement enterprise audit logging and operational telemetry.
• Contribute to CI/CD pipelines, automated builds, and Dev Sec Ops  processes.
• Perform unit, integration, and API testing using tools such as Postman, Swagger/OpenAPI, or equivalent.
• Participate in Agile development, Git‑based version control, and secure configuration management.
• Integrate enterprise ICAM/CIAM platforms in cloud or hybrid environments.
• Ensure identity solutions comply with NIST SP 800‑63 Digital Identity Guidelines and Zero Trust Architecture principles.
• Support DoD cybersecurity requirements, including RMF and STIG compliance.
