  • Work side-by-side with customer delivery leads, backend engineers, and UX designers to ensure successful, end-to-end deployments
  • Translate customer and policy requirements into secure system designs and production-ready implementations across mobile and backend components
  • Act as a trusted technical advisor to public-sector partners, guiding them through mobile security, identity standards, and platform best practices
  • Build and ship privacy-preserving applications that meet public-sector requirements for security, accessibility, and compliance
  • Integrate mobile applications with backend identity services, cryptographic libraries, and platform APIs
  • Contribute to shared Rust and cross-platform libraries that run across backend services, mobile devices, and the browser
  • Support customer deployments, debugging, and operational needs in real-world environments—whatever it takes to ensure success
  • Step outside your primary stack when needed, contributing across mobile, backend, and infrastructure as projects evolve
  • Represent SpruceID directly with partners during pilots, launches, and ongoing engagements

Qualifications

  • Strong engineering fundamentals with the ability and willingness to contribute beyond mobile when needed
  • Excellent communication skills and experience working directly with customers, ideally in a consulting or delivery-focused role
  • A proactive, “can do / will do” mindset and comfort operating outside your primary area of expertise

We believe that architectures that enable individual autonomy in the digital world are necessary for free societies and dynamic economies to thrive.
