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.

We’re looking for a Senior Full-Stack Engineer to join our forward-deployed engineering team. You’ll work directly with state governments and public sector partners, and enterprise clients to design, build, and deploy impactful identity solutions. This role blends hands-on software development, technical consulting, and customer success: ideal for someone who thrives at the intersection of technology and mission-driven impact.

This is a fully remote role open to candidates based in the United States.

What You'll Do

  • Design, build, and deploy full-stack solutions for state governments and public sector partners.
  • Collaborate with customer delivery leads, engineers, and UX designers to ensure successful deployments.
  • Translate customer requirements into technical architectures and production-ready systems.
  • Serve as a trusted technical advisor for partners adopting open identity standards and privacy best practices.
  • Build backend services and full-stack web or mobile apps that meet public sector security, privacy, and accessibility standards.
  • Contribute to Rust codebases that run across backend, mobile, and browser environments.
  • Manage customer deployments and provide post-launch technical support.
  • Qualifications

  • 2+ years of experience building backend systems in statically typed languages (Rust, Go, C#, or Java).
  • Strong background in modern web frontends (React, TypeScript, or similar) with an eye for accessibility and security.
  • Proven ability to lead cross-functional engineering efforts and deliver production-grade systems.
  • Strong appreciation for open-source software, standards-based design, and community-driven development.
  • Hands-on experience with cloud infrastructure (AWS, GCP, or Azure) and DevOps practices.
  • Excellent communication skills and comfort working directly with customers or stakeholders.
  • Based in the U.S., excited to collaborate with state government partners.
  • Nice to Have

  • Experience with digital identity, cryptography, data privacy, or blockchain technologies (e.g., Verifiable Credentials, Decentralized Identifiers, OAuth, OpenID Connect).
  • Familiarity with PostgreSQL, GraphQL, or RESTful API design and development.
  • Understanding of CI/CD pipelines, infrastructure as code, and automation using Terraform, or similar tools.
  • Exposure to mobile app development (React Native, Flutter, or similar frameworks).
  • Experience in security engineering, access control, federated identity, or PKI systems.
  • Prior work in public sector, government technology, or other high-compliance environments.
  • Interest in usability, accessibility (WCAG, Section 508), and inclusive product design.
  • Contributions to open-source projects or participation in digital identity standards bodies (W3C, DIF, IETF) is a plus.
