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.
Key Responsibilities
- 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 & Requirements
- 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.
Preferred / Nice-to-Have Qualifications
- 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. At SpruceID, we value diversity of perspectives and backgrounds. We are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity, or veteran status.
About Spruce
Spruce, founded in 2020 by Wayne Chang and Gregory Rocco in New York, builds open-source identity and data control infrastructure for Web3. Its products, SpruceID and Kepler, provide decentralized identifiers, credential wallets and storage that let users control authentication and data sharing across apps without centralized providers, using DIDs and verifiable credentials. Headquartered in New York with a distributed team, Spruce collaborates with Ethereum Foundation, ENS and government pilots on privacy-preserving identity standards. The company emphasizes open standards, cryptographic verifiability and developer tooling over custodial identity. Backed by leading investors, Spruce advances self-sovereign identity research and interoperability. Its standards collaborations with ENS, Ethereum Foundation and government pilots advance verifiable credential adoption while preserving user control over selective disclosure. Expect a research and standards-driven culture that values privacy engineering, open collaboration and building durable, user-controlled identity rails for the ecosystem.
