Finance Systems Engineer, Tax

About the role

Anthropic is building reliable, interpretable, and steerable AI systems. The Tax Technology function within Finance Systems needs a technologist who can design, implement, and maintain the tax‑related integrations that make revenue and purchasing flows bookable, taxable, and auditable from day one.

Key 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, covering 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, such as indirect tax reconciliations, provision and research credit pipelines, transfer‑pricing datasets, and exemption validation tools.
• Maintain production connection points between the tax stack and Anthropic’s data infrastructure, feeding the central ingestion layer.
• Develop SOX‑aware IPE and control‑total tooling on tax data flows, including ingestion control totals, source‑to‑target tie‑outs, and audit‑ready evidence pipelines.
• Design tooling that leverages Claude to automate tax work and provide non‑technical tax colleagues with self‑serve access to data, calculations, and evidence.
• Serve as the technical owner for vendor implementation handoffs, staying involved through build and post‑go‑live support.
• Partner with Billing Engineering, Data Platform, Tax, Treasury, and Product teams to keep the tax stack optimized and compliant as new products and jurisdictions are added.
