Key Responsibilities

Design, build, and maintain full‑stack components of the digital credentials platform using modern JavaScript frameworks (React, Vue, Angular), Python, Java, HTML5, CSS3 and similar stacks.
Develop and extend open source Open Wallet Foundation ACA-PY, credential exchange protocols, DID resolution services, and secure messaging workflows.
Implement credential lifecycle features—including issuance, presentation, revocation, and IETF Status List support—aligned with W3C Verifiable Credentials and decentralized identity standards.
Build secure APIs and asynchronous services to support verification flows, trust framework compliance, and interoperability across issuers, holders, verifiers, and external systems.
Apply strong security practices, implementing cryptographic operations, secure key management, and hardware‑backed storage patterns.
Ensure back‑end integrations follow best practices for authentication, authorization, encryption, and secure data exchange.
Support front‑end user interfaces and admin dashboards that interact with credential services, ensuring usability, performance, and accessibility.
Develop automated tests (unit, integration, API‑level), participate in code reviews, and uphold high engineering standards across the stack.
Collaborate closely with architects, DevOps, security specialists, and cross‑ministry stakeholders to ensure end‑to‑end functional integrity.
Document system designs, workflows, schema definitions, and operating procedures to support maintainability and knowledge sharing.
Participate in Agile ceremonies, support milestone planning, and assist in troubleshooting distributed digital credential environments.

Must-Haves:

- In-depth development experience with JWT/JWS, PKI (X.509), OAUTH2, and SHA/SHA2.
- Build user‑facing components, dashboards, or admin consoles that interface with digital credential services using modern JavaScript frameworks (React, Vue, Node.js), Python, Java, HTML5, CSS3 and similar stacks.
- Integrate backend systems into broader enterprise and cross‑ministry ecosystems using REST APIs, event‑driven services, and secure messaging systems.
