  3. PEPPOL Leadership: Enhance and maintain our proprietary PEPPOL e-invoicing access point, ensuring alignment with the latest global framework updates.
  4. Blockchain Innovation: Maintain and evolve our blockchain service, converting invoices into encrypted NFTs via Solidity smart contracts.
  5. Quality Assurance: Write robust unit tests and end-to-end integration scenarios to ensure a fully automated, fail-safe deployment pipeline.
  6. Technical Research: Provide technical documentation and strategic solutions based on evolving PEPPOL standards and Software Partner updates.

Skills & Experience Required

  1. Education: Tertiary degree in Computer Science, Software Engineering, or a related field.
  2. Experience: 4+ years in professional software development using modern JavaScript/TypeScript.
  3. FinTech Domain: 4+ years of experience working with enterprise APIs (Xero, MYOB, QBO).
  4. E-Invoicing Expertise: 2+ years of hands-on experience with PEPPOL, XML schematrons, and a solid understanding of AS4 transport mechanisms.
  5. Web Development: Proven track record of building responsive, user-friendly web applications.
  6. Blockchain: 1+ years of experience with Solidity and Smart Contracts.

  1. Frontend: React, Styled Components, JSS, TypeScript.
  2. Backend: Node.js, RESTful APIs (JSON-based), and decoupled architecture.
  3. Testing: Cypress and Jest.
  4. Cloud & DevOps: AWS (CloudFront, Lambda, API Gateway), CI/CD practices, and DevOps culture.
  5. Observability: Experience with logging and monitoring tools (Splunk, Kibana, New Relic).
