hirify.global builds privacy-preserving, standards-based digital identity and credentialing solutions for governments and enterprises, including public-sector partners such as the California Department of Motor Vehicles.

What you will do

• Design, build, and maintain production-grade native mobile applications and SDKs for digital identity and credentialing, including secure digital identity wallets.
• Develop mobile capabilities for receiving, storing, managing, and presenting digital credentials, including device and biometric authentication, secure storage, cryptographic operations, and privacy-preserving data exchange.
• Integrate identity standards, backend APIs, issuance systems, verification services, and platform security features into iOS and Android applications.
• Collaborate with engineers, designers, product teams, and government partners to translate complex requirements into accessible mobile experiences.
• Contribute to Rust-based shared libraries and cross-platform components supporting mobile, backend, and browser environments.
• Own the mobile lifecycle from architecture and implementation through testing, releases, monitoring, optimization, and continuous improvement; Staff-level candidates also provide technical leadership and mentorship.

Requirements

• 5+ years of professional software engineering experience, including significant experience building and shipping production mobile applications; Staff-level candidates need additional experience leading mobile architecture and major technical initiatives.
• Deep expertise in native iOS development with Swift, SwiftUI, and UIKit and/or native Android development with Kotlin, Jetpack Compose, and Android SDK.
• Strong understanding of mobile architecture, platform security, application lifecycle management, concurrency, performance, and reliability.
• Experience with mobile security capabilities such as iOS Keychain, Secure Enclave, Android Keystore, hardware-backed key storage, or biometric authentication.
• Ability to design and deliver complex user-facing mobile applications from initial architecture through production deployment.
• Experience integrating mobile applications with backend services, APIs, and authentication systems.
• Familiarity with secure software development, cryptographic concepts, and protecting sensitive user information.
• Strong engineering judgment, ability to navigate ambiguity, cross-functional collaboration, and communication of technical tradeoffs to technical and nontechnical audiences.
• Appreciation for open-source software, open standards, interoperability, and privacy-first product design.
• Must be based in the United States and work remotely.

Nice to have

• Experience with mobile driver's licenses, digital identity wallets, verifiable credential applications, or digital document solutions.
• Familiarity with ISO/IEC 18013-5, ISO/IEC 18013-7, W3C Verifiable Credentials, OpenID4VCI, OpenID4VP, or related digital identity standards.
• Experience with NFC, Bluetooth Low Energy, QR code, or proximity-based credential exchange protocols.
• Knowledge of public key cryptography, PKI, certificate validation, digital signatures, key management, and device attestation.
• Experience integrating Apple Wallet, Google Wallet, or other platform-level digital credential capabilities.
• Familiarity with Rust and integrating shared Rust libraries into native mobile applications.
• Experience with React Native, Flutter, Kotlin Multiplatform, or similar cross-platform technologies.
• Knowledge of OAuth 2.0, OpenID Connect, passkeys, WebAuthn, or federated identity systems.
• Experience designing mobile SDKs or reusable libraries, managing App Store and Google Play releases, mobile CI/CD, automated testing, crash reporting, and production observability.
• Familiarity with accessibility practices including WCAG, Section 508, VoiceOver, and TalkBack; experience in government technology, regulated industries, financial services, or other security-sensitive environments.
• Contributions to open-source projects or digital identity standards communities such as W3C, OpenID Foundation, IETF, or ISO.

Culture & Benefits

• Work on privacy-preserving, open, and interoperable identity technology with large-scale public-sector impact.
• Collaborate on challenging problems across mobile platforms, applied cryptography, open standards, and government technology.
• Meaningful ownership of architecture and product outcomes in a fully remote engineering role.
• Commitment to equal employment opportunity across diverse backgrounds and protected characteristics.
