CORE WORK ACTIVITIES

Product Strategy and Roadmap

• Own the vision and multi-release roadmap for tax integration across Coupa P2P, Coupa S2C, and Birchstreet.

• Prioritize the backlog against compliance requirements, technical dependencies, financial impact, and platform constraints.

Technical Solution and Integration Design

• Define integration architecture and data flows between Coupa, Birchstreet, Vertex (O Series or Vertex Cloud), middleware, and the ERP.

• Specify API requirements, field mappings, authentication, error handling, retry logic, and idempotency for real-time and batch tax calls.

• Own technical requirements for master data: ship-to/ship-from, product and commodity tax codes, supplier tax attributes, exemption certificates, and chart of accounts mappings.

• Define tax calculation behavior at each stage (requisition, PO, receipt, invoice, credit memo, expense), including PO-to-invoice tax variances, tolerance handling, and supplier-charged vs. self-assessed use tax.

• Define non-functional requirements: performance, scalability, availability, latency, monitoring, and disaster recovery.

• Partner with architects on security, data privacy, and environment strategy (sandbox, UAT, production).

Delivery and Execution

• Write clear epics, user stories, technical specifications, and acceptance criteria. Lead sprint planning, backlog grooming, and release readiness.

• Collaborate daily with developers, QA, DevOps, Coupa and Birchstreet administrators, Vertex consultants, and implementation partners.

• Drive test strategy, including integration, regression, performance, and end-to-end testing of tax scenarios across jurisdictions, with automation where possible.

• Lead UAT with Tax, AP, and Procurement; manage cutover, data migration, and hypercare for go-lives across entities and countries.

• Troubleshoot integration defects and production incidents, performing root-cause analysis with logs, payloads, and tax determination results.

Governance, Compliance, and Operations

• Ensure traceability of tax determinations, overrides, and audit logs to support SOX, internal audit, and tax audit requirements.

• Define observability and KPIs: tax calculation accuracy, API success rates, exception volumes, override rates, and processing latency.

• Track Vertex releases, Coupa and Birchstreet release cycles, and regulatory changes (e-invoicing mandates, new jurisdictional rules), and plan upgrades and regression impacts.

Stakeholder Leadership

• Translate between technical and non-technical audiences, including Tax, Procurement, AP, Finance, and executive sponsors.

• Communicate status, risks, and decisions to operating committees.

Change Management & Communication

• Develop stakeholder engagement, communication, and training plans

• Partner with change management teams to drive user adoption across global business units
