About SpruceID
SpruceID builds privacy-preserving, standards-based digital identity and credentialing solutions that give individuals control of their information while enabling governments and enterprises to deliver secure, interoperable services. We partner with public-sector organizations, including the California Department of Motor Vehicles (DMV), to modernize how identity is issued, stored, presented, and verified.
We're looking for a Senior or Staff Forward-Deployed Engineer to help build and scale the next generation of digital identity experiences. You'll play a key technical role in developing secure, intuitive mobile applications and SDKs that enable people to use digital credentials in everyday interactions.
This role combines deep mobile engineering expertise, security-conscious architecture, and hands-on collaboration with government partners. You'll work at the intersection of mobile platforms, cryptography, open standards, and real-world deployments, helping deliver digital identity infrastructure that can serve millions of people.
This is a fully remote role open to candidates based in the United States.
What You'll Do
Design, build, and maintain production-grade mobile applications for digital identity and credentialing, with a particular focus on initiatives supporting the government partners.
Lead the development of secure digital identity wallets that enable individuals to receive, store, manage, and present digital credentials.
Develop and maintain native iOS and/or Android applications, with a strong emphasis on platform capabilities, performance, reliability, security, and user experience.
Architect and implement mobile features involving secure credential storage, device authentication, biometric authentication, cryptographic operations, and privacy-preserving data exchange.
Integrate emerging identity standards into mobile applications and SDKs.
Work with engineers, designers, product teams, and government partners to translate complex requirements into elegant, accessible mobile experiences.
Build and maintain mobile integrations with backend APIs, identity issuance systems, credential verification services, and platform security features.
Contribute to Rust-based shared libraries and cross-platform components that support secure identity functionality across mobile, backend, and browser environments.
Own the mobile engineering lifecycle, from architecture and implementation through testing, release management, production monitoring, and ongoing improvements.
Help establish mobile engineering best practices, including automated testing, CI/CD, observability, secure development, and application performance optimization.
For Staff-level candidates, provide technical leadership across projects, drive architectural decisions, mentor engineers, and help define the long-term direction of SpruceID's mobile identity platform.
Qualifications
5+ years of professional software engineering experience, with significant experience building and shipping production mobile applications. Staff-level candidates should bring additional experience leading mobile architecture and major technical initiatives.
Deep expertise in native iOS development (Swift, SwiftUI, UIKit) and/or native Android development (Kotlin, Jetpack Compose, Android SDK).
Strong understanding of mobile application architecture, platform security, application lifecycle management, concurrency, performance, and reliability.
Experience working with mobile security capabilities such as iOS Keychain, Secure Enclave, Android Keystore, hardware-backed key storage, or biometric authentication.
Demonstrated 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 practices, cryptographic concepts, and protecting sensitive user information.
Strong engineering judgment, ability to navigate ambiguity, and experience collaborating across engineering, product, design, and external stakeholders.
Excellent communication skills, including the ability to explain technical tradeoffs and architectural decisions to both technical and nontechnical audiences.
Appreciation for open-source software, open standards, interoperability, and privacy-first product design.
Based in the United States (remote) and excited to work on digital identity infrastructure with public-sector partners.
Nice to Have
Experience developing mobile driver's licenses (mDLs), 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 implementing NFC, Bluetooth Low Energy (BLE), QR code, or proximity-based credential exchange protocols.
Understanding 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, including integrating shared Rust libraries into native mobile applications through FFI or other cross-language bindings.
Experience with cross-platform mobile development using React Native, Flutter, Kotlin Multiplatform, or similar technologies.
Knowledge of OAuth 2.0, OpenID Connect, passkeys, WebAuthn, or federated identity systems.
Experience designing mobile SDKs or reusable libraries consumed by other engineering teams or external partners.
Experience with App Store and Google Play release management, mobile CI/CD, automated testing, crash reporting, and production observability.
Familiarity with accessibility best practices, including WCAG, Section 508, VoiceOver, and TalkBack.
Prior experience working in government technology, regulated industries, financial services, or other security-sensitive environments.
Contributions to open-source projects or participation in digital identity standards communities such as W3C, OpenID Foundation, IETF, or ISO.
