Senior Mobile Application Developer @ SecureAuth Corporation

SecureAuth is on a mission to eliminate passwords and revolutionize how people authenticate. We are looking for a Senior Mobile Application Developer to lead the implementation of advanced authentication flows – especially passkeys (WebAuthn / FIDO2) – in our cross-platform mobile app, SecureAuth Authenticate. In this role, you will build seamless, secure login experiences that leverage the latest passwordless technologies on both iOS and Android. If you are passionate about cutting-edge mobile development and creating user-friendly security solutions, this is an opportunity to make a significant impact on next-generation identity management.

About SecureAuth

With hundreds of customers already using our solutions to solve challenges ranging from digital transformation to zero trust, SecureAuth is leading a revolution in the IAM industry with a game-changing approach to authentication and access management. The company is headquartered in Irvine, CA with offices in Argentina, Canada, and Europe. We are a global company with a remote-first work culture driven by passionate employees who embrace delivering innovative solutions that let the right people in and keep the wrong people out, giving employees and customers peace of mind.

Required Qualifications :

• 5–8+ years of professional mobile application development, with a strong track record of building and shipping native iOS and Android apps (enterprise or consumer, at scale)
• Deep knowledge of iOS development, including Objective-C++ and Objective-C (for low-level or legacy integrations), as well as Swift and SwiftUI for modern UI development. Comfortable working with iOS frameworks and extensions (e.g. implementing an AutoFill Credential Provider Extension for passkeys on iOS)
• Strong proficiency in Android development using Kotlin. Experience with modern Android libraries and patterns such as Jetpack Compose for UI and AndroidX libraries. Ability to build Android services and components (e.g. an Android CredentialProviderService for the Android 14+ Credential Manager API) and handle different Android OS versions
• Hands-on experience with device security features – including using the Secure Enclave on iOS and Android Keystore / StrongBox – for key generation and storage. Familiarity with biometric authentication flows (fingerprint, face recognition prompts) and ensuring sensitive data is handled securely
• Working understanding of WebAuthn, FIDO2, or similar cryptographic authentication protocols. You know how public / private key authentication works and have implemented or used cryptographic signing workflows (even if not in production, you grasp the concepts deeply)
• Ability to write high-quality, secure, and maintainable code. Experience implementing thorough testing (unit and integration tests) for mobile apps. Familiarity with secure coding guidelines and tools to detect and remediate vulnerabilities in mobile applications
• Comfortable with mobile CI / CD pipelines and app distribution processes. For example, configuring automated builds, tests, and deployments to the App Store and Google Play. Knowledge of managing provisioning profiles, certificates, signing, and Play Console release tracks
• Solid understanding of RESTful API integration and network security in mobile apps. While this role is mobile-focused, you should be adept at working with backend services (authentication APIs, cloud sync endpoints) and handling data serialization, encryption, and synchronization with cloud systems
• Excellent communication and teamwork skills. Proven ability to work closely with designers, product managers, and backend engineers to shape feature requirements and deliver end-to-end functionality. Comfortable in an agile development environment, giving and receiving feedback on code and design
• Background in security, identity, or authentication domains is a plus. For example, experience building multi-factor authentication (MFA) apps, identity verification tools, or zero-trust security products will help you hit the ground running

Build, enhance, and maintain native iOS and Android codebases for SecureAuth’s mobile authentication app, ensuring high performance, security, and reliability, Integrate passkey authentication (WebAuthn / FIDO2) into the app by developing platform-specific components – including an iOS Credential Provider Extension and an Android CredentialProviderService – to interface with each OS’s passwordless authentication framework, Work extensively with hardware-backed key storage (Apple Secure Enclave and Android StrongBox / Keystore). Implement generation and secure storage of cryptographic keys, and use biometric prompts (Face ID, Touch ID, Android Biometric Authentication) to unlock credentials when needed, Design and code robust cryptographic key management and signing flows. Ensure secure registration, authentication, and key synchronization via SecureAuth’s cloud APIs so that users’ passkeys and credentials seamlessly sync across devices, Extend existing authentication methods (such as QR code enrollment and push notification login) to incorporate passkey-based login. For ex., enable users to scan a QR code and confirm login using a passkey, or approve a push notification with a biometric-unlocked passkey instead of a password, Write clean, testable, well-documented code. Establish unit tests and work with QA to automate testing of security features. Perform code reviews to uphold best practices for secure coding and maintainability in an enterprise mobile app, Work closely with cross-functional teams – including UX / UI designers, product managers, and backend cloud engineers – to plan new features and ensure the mobile app integrates smoothly with SecureAuth’s platform.
