Senior Mobile Authentication Integration Engineer (iOS/Android)

Peraton is seeking a highly experienced Mobile Authentication 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 native mobile identity integration to support a Federal customer's secure mobility and authentication programs with emphasis on implementing phishing-resistant authentication, enterprise identity workflows, and secure SDK integrations into native iOS and Android applications.

* Implement FIDO2/WebAuthn, passkeys, and other phishing-resistant authentication mechanisms
* Integrate CAC/PIV, Purebred, and other government-issued mobile credentials
* Manage secure storage of credentials and tokens using iOS Keychain and Android Keystore
* Implement device registration, trusted device policies, and mobile biometric authentication (Face ID, Touch ID, Android Biometrics)
* Apply mobile application security controls including OWASP Mobile Top 10, certificate pinning, TLS configuration, and secure network communication
* Troubleshoot authentication, SDK, API, and mobile platform integration issues

Design mobile enrollment workflows compliant with NIST SP 800-63.

Implement secure application routing using Universal Links and Android App Links.
* Implement proxy user experiences supporting dependent access.
* Design seamless in-app authentication experiences eliminating browser redirects.
* Support integration of native mobile applications with enterprise IAM/CIAM systems used across Federal agencies
