This is a remote position.

NetForemost is looking for a Full Stack Developer with experience in .NET, SQL, Azure, ABP.IO, and n8n integrations to support the development of an invoice integration between the Arriba portal, n8n, and QuickBooks.

The developer will be responsible for building portal-side invoice triggers, tenant-level integration configuration, webhook-based communication, and n8n workflows that send invoices to QuickBooks and update Arriba when invoices are paid. This role requires someone who can move comfortably between application code, API integrations, workflow automation, and debugging cross-system data flows.

Key Responsibilities

  • Build and maintain full stack features using .NET, ABP.IO, SQL, and Azure.

  • Implement tenant-level integration settings, including:

    • Enable/disable integration per tenant

    • Webhook URLs per event

    • Shared secret or authentication references

    • Optional invoice source/type mapping

    • Test webhook action

  • Develop backend event triggers for invoice-related events, including:

    • invoice.created

    • invoice.voided

    • Invoice unsubmitted/deleted scenarios

  • Create secure outbound webhook payloads from Arriba to n8n.

  • Build and maintain n8n workflows to:

    • Receive Arriba invoice events

    • Transform invoice payloads

    • Create invoices in QuickBooks

    • Void/delete invoices in QuickBooks

    • Detect or receive QuickBooks payment updates

    • Call Arriba’s mark-as-paid endpoint

  • Integrate with QuickBooks APIs for invoice creation, voiding, and payment reconciliation.

  • Add basic observability and traceability, including correlation IDs, logs, and error visibility.

  • Work with QA to validate create, void, unsubmit, delete, and mark-paid flows.

  • Document integration setup, configuration steps, and handoff notes.

  • Collaborate with the project manager, QA engineer, and client stakeholders during UAT.
