This role is focused primarily on designing, implementing, and optimizing enterprise tax solutions using Vertex , with strong engineering knowledge of system integrations across Finance, ERP, Billing, and Revenue platforms. The ideal candidate brings deep expertise in Vertex configuration and indirect tax processes (Sales & Use Tax, VAT/GST), combined with hands-on technical experience integrating Vertex with enterprise systems via APIs, middleware, and event-driven architectures. This is not a middleware-only role — it is a tax systems engineering role with integration architecture responsibilities.
