We are looking for a Senior Node.js Developer to join our product engineering team building a SaaS product that integrates deeply with Coupa and other enterprise applications. The ideal candidate will have strong hands-on expertise in Node.js, TypeScript, PostgreSQL, REST APIs, data transformation, and enterprise integrations , with practical experience working with Coupa or similar procurement/ERP platforms . This is aWFHposition.
Required Qualifications
4+ years of professional software development experience building production-grade backend systems — ideally SaaS products or enterprise integration platforms, not just prototypes.
Strong hands-on expertise in Node.js, TypeScript/JavaScript, and SQL against PostgreSQL.
Solid grounding in software architecture, API design, error handling/logging, and production troubleshooting.
Experience writing automated unit and integration tests for backend services.
Hands-on experience building or supporting integrations with Coupa (or a comparable enterprise procurement/ERP platform) via REST/JSON APIs, including authentication, request/response handling, and error handling.
Working knowledge of core procurement objects and flows (suppliers, requisitions, purchase orders, invoices, receipts) sufficient to reason about integration behavior.
Proven experience with data mapping, transformation, validation, and synchronization between source and target systems, and the ability to independently scope an integration's API calls, mappings, and error handling from a requirement.
Experience troubleshooting integration failures using logs, API payloads, and database records.
Experience with Git-based workflows: pull requests, branching, and code review.
Ability to read and troubleshoot CI/CD pipeline failures.
Hands-on AWS experience, including containerized deployments (ECS or equivalent, with underlying Docker knowledge), CloudWatch, and S3.
Experience supporting customer-facing implementations or integrations, and distinguishing customer-specific configuration issues from product-level defects.
Excellent written and verbal English, with the ability to produce clear defect write-ups, technicalspecs,and runbooks.
Hands-on experience with AI-assisted development tools (e.g., Claude Code, GitHub Copilot, Cursor), and able to describe how you use them while maintaining code quality and review standards.
Preferred Qualifications
Experience building a commercial SaaS product rather than working exclusively on individual customer integrations.
Deep experience with Coupa integration architecture and Coupa APIs.
Experience integrating Coupa with NetSuite, Sage Intacct, Microsoft Dynamics, SAP, Oracle, or other ERP platforms.
Experience with Coupa customers, Coupa implementation partners, or Coupa's integration ecosystem, including working directly with Coupa Support to escalate platform-side issues.
Experience designing multi-tenant SaaS integrations where a single product supports different customer configurations and integration requirements.
Experience with Node.js async/queue-based patterns (e.g., BullMQ, AWS SQS), webhooks, scheduled integrations, retry mechanisms, and idempotency for high-volume enterprise data synchronization.
Familiarity with observability/APM tooling beyond CloudWatch (e.g., Datadog, New Relic, Sentry).
Familiarity with enterprise security practices: OAuth2, credentials/secrets management (e.g., AWS Secrets Manager or Parameter Store), audit logging, and compliance requirements.
Experience working under formal change management, release management, audit, security, or compliance processes.
Experience with embedded, docked, plug-in, or extensible application architectures.
Basic procurement/accounting literacy (PO matching, GL coding, tax/currency handling) relevant to invoice and PO data mapping.
