Full description
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 to modernize how identity is issued, verified, and used.
As a Senior Mobile Engineer , you will sit at the intersection of engineering, customer delivery, and digital identity. You will work directly with state governments and other public-sector partners to design, build, and deploy mobile-first identity solutions, often serving as the primary technical representative of SpruceID in the field.
This role combines hands-on mobile development with consulting, systems design, and customer success. While much of our current work leverages Flutter, we are looking for engineers who are comfortable operating across multiple mobile environments—including native (iOS/Android) and cross-platform frameworks such as Flutter or React Native—as our technology stack evolves over time.
You will ensure SpruceID’s mobile technology is deployed securely, effectively, and with lasting real-world impact, while contributing to decisions about how our mobile architecture grows and adapts.
This job is fully remote within the US.
What You'll Do
-
Lead the design and development of mobile applications for state governments and enterprise customers across native and cross-platform environments (e.g., Flutter, React Native, iOS, Android)
-
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
