About the role

  • ID.me is seeking a Senior Software Engineer to join the Wallet/Authentication Platform team, with a focus on the client-side and credential-layer experiences that power the ID.me digital identity wallet.
  • Our team is investing heavily in next-generation wallet capabilities: W3C Verifiable Credentials, ISO 18013-5 mobile driver's licenses (mDL), passkeys, and cryptographically-bound credentials secured by device hardware.
  • You will bring deep experience in mobile development, secure hardware APIs, and digital credential standards to help us ship these capabilities securely and at scale.

Responsibilities

  • Digital Wallet Client Development: Build and maintain the client-side wallet experience - credential storage, management, and presentation flows across iOS, Android, and web.
  • Deliver seamless, secure UX for issuing, holding, and presenting Verifiable Credentials and other identity artifacts.
  • Verifiable Credentials & Standards Implementation: Implement and evolve support for W3C Verifiable Credentials (VC Data Model), Decentralized Identifiers (DIDs), and related protocols (SD-JWT VC, mdoc/ISO 18013-5).
  • Design credential lifecycles with strong cryptographic guarantees for issuance, binding, revocation, and presentation.
  • Cross-Functional Collaboration: Partner with Product, Design, Security, Identity Standards, and adjacent engineering teams to ship cohesive credential experiences.
  • Mentorship & Leadership: Provide technical guidance to junior engineers through code reviews, design discussions, and pairing. Help establish and reinforce team standards for secure client development.
  • Build and maintain the client-side wallet experience - credential storage, management, and presentation flows across iOS, Android, and web.
  • Implement and evolve support for W3C Verifiable Credentials (VC Data Model), Decentralized Identifiers (DIDs), and related protocols (SD-JWT VC, mdoc/ISO 18013-5).

Requirements

  • Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent practical experience).
  • 5+ years of professional software development experience, with significant focus on mobile or client-side engineering.

Nice to have

  • Experience implementing W3C Verifiable Credentials (VC Data Model 1.x/2.x), Decentralized Identifiers (DIDs), or related decentralized identity standards (SD-JWT VC, mdoc/ISO 18013-5 mDL).
  • Hands-on experience with platform secure hardware APIs: iOS Secure Enclave, iOS Keychain, Android Keystore, Android StrongBox, or equivalent Trusted Execution Environment (TEE) primitives.
  • Familiarity with cryptographic key management in mobile contexts - key generation, attestation, binding, rotation, and secure deletion.
  • Familiarity with passkeys/FIDO2/WebAuthn, especially platform authenticator integration on iOS and Android.
  • Experience with authentication and identity protocols: OAuth 2.0, OpenID Connect (OIDC), OIDC for Verifiable Presentations (OID4VP), or SIOP v2.
  • Familiarity with NIST SP 800-63 identity assurance levels and what they mean for credential binding and presentation security.
  • Experience with React or modern web frameworks for building wallet-style web client experiences.
  • Familiarity with CI/CD pipelines, automated testing frameworks, and mobile-specific testing tooling.
