Job summary

United States Digital Space LLC is hiring a Tax Technologist to own tax-related changes across billing and ERP integrations, and to build tooling for audit-ready tax data pipelines. The role partners with Tax, Data Science, Billing Engineering and Product to keep the tax stack compliant and scalable as the business grows.

The ideal candidate has 7+ years in tax technology or finance systems, strong Python/SQL, and experience with SOX-compliant data flows.

Qualifications

• Hands-on experience building or owning production integrations against billing platforms, ERPs, or enterprise tax/finance systems.
• Tax-systems fluency in at least one domain (indirect tax engines, corporate tax provision or compliance tooling, withholding).
• Proficiency writing production-grade Python with testing and code-review discipline.
• SQL proficiency to build reconciliations and validate data end to end.
• Experience building or operating SOX-aware data flows, such as IPE, control totals, or documented/testable pipelines.

Responsibilities

• Own tax-related changes in the billing codebase and the billing-to-tax-engine integration, including withholding tax considerations.
• Lead the AP tax engine implementation across ERP-connected purchasing flows: data migration, integration pipelines, parallel-run reconciliation, e-invoicing and go-live validation.
• Build and iterate tax-specific products and internal tooling across the full tax stack, including indirect tax reconciliations, provision and research credit data pipelines, transfer pricing datasets, withholding tracking, and exemption and validation tooling.
• Own the production connection points between the tax stack and our data infrastructure, feeding the central ingestion layer.
• Build SOX-aware IPE and control-total tooling on tax data flows: ingestion control totals, source-to-target tie-outs, and evidence pipelines that stand up to external audit.
• Design and build tooling that applies Claude to tax work and gives non-technical tax colleagues self-serve access to data, calculations, and evidence.
• Serve as the technical owner for vendor implementation handoffs, in the room during the build and accountable after go-live.
• Partner with Billing Engineering, Data Platform, Tax, Treasury and Product to keep the tax stack optimized and compliant as new products and jurisdictions come online.

We think this makes representation even more important, and we strive to include a range of diverse perspectives on our team.
