DET is seeking a Senior Tax Systems Engineer (Vertex) to join our IT Finance Engineering team.

Experience integrating Vertex with ERP, billing, and revenue systems via REST/SOAP APIs, middleware, or custom frameworks
Solid understanding of Quote-to-Cash and Record-to-Report processes
Strong engineering foundation in API design, data mapping, JSON/XML transformations, and secure integrations
Experience with integration platforms (e.g., MuleSoft, Boomi, Informatica)
Strong troubleshooting skills across tax, integration, and financial data flows
Experience working in Agile environments with CI/CD and version control (Git)
Bachelor’s degree in Computer Science, Engineering, Finance Systems, or a related field

Partner with Finance, Tax, Revenue Operations, and Engineering to translate regulatory and business requirements into scalable technical solutions
Troubleshoot tax calculation issues, integration failures, and reconciliation discrepancies
