Finance Systems Engineer, Tax

Details

Anthropic's Tax Technology function sits within Finance Systems and owns the systems that make revenue and purchasing activities bookable, taxable, and auditable. The role will build integrations, tooling, and production code connecting tax systems with billing, ERP, and data warehouse systems. It covers indirect tax, corporate income tax and provision, withholding tax, R&D credits, and transfer pricing, while partnering with Tax, Data Science, Billing Engineering, Product, Treasury, and Data Platform teams.

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, including data migration, integration pipelines, parallel-run reconciliation, e-invoicing, and go-live validation.
• Build and iterate tax-specific products and internal tooling across the tax stack, including indirect tax reconciliations, provision and research credit data pipelines, transfer pricing datasets, withholding tracking, and exemption and validation tooling.
• Own production connection points between the tax stack and the data infrastructure, feeding the central ingestion layer.
• Build SOX-aware IPE and control-total tooling for tax data flows, including ingestion control totals, source-to-target tie-outs, and audit evidence pipelines.
• Design and build tooling that applies Claude to tax work and gives non-technical tax colleagues self-service access to data, calculations, and evidence.
• Serve as the technical owner for vendor implementation handoffs, participating during the build and remaining accountable after go-live.
• Partner with Billing Engineering, Data Platform, Tax, Treasury, and Product to optimize and maintain compliance of the tax stack as new products and jurisdictions come online.

Requirements

• Hands-on experience building or owning production integrations with billing platforms, ERPs, or enterprise tax and finance systems.
• Tax-systems fluency in at least one domain, such as indirect tax engines, corporate tax provision or compliance tooling, withholding, research credit, or transfer pricing systems.
• Experience gained in a tax-technology practice, tax software vendor, or in-house tax-systems team.
• Proficiency writing production-grade Python, with testing and code-review discipline.
• SQL proficiency sufficient to build reconciliations and validate data end to end.
• Experience building or operating SOX-aware data flows, such as IPE, control totals, or documented and testable pipelines.
• Ability to work independently in a constantly changing and fast-paced environment.
• Ability to work directly with vendors, auditors, engineers, and tax professionals without an intermediary.
• Minimum education of a bachelor's degree or equivalent combination of education, training, and experience.

Preferred Qualifications

• 7+ years of experience in tax technology, finance systems engineering, or a closely related field.
• Experience owning changes inside a shared production codebase alongside a product engineering team.
• Warehouse and analytics-engineering skills, such as dbt or BigQuery.
• Experience across multiple tax domains, including sales/use tax, VAT/GST, corporate income tax and provision, withholding, research credit, and transfer pricing data.
• Experience building internal tools or interfaces for non-technical finance or tax users.
• Experience building with LLMs or applying AI to finance or tax work.
• Marketplace, usage-based, or platform billing exposure.
• Experience taking over vendor-built systems and hardening them for long-term ownership.
• UAT design and change-management experience on finance-systems implementations.
• A record of novel AI applications for foundational tax tasks or problems.

Compensation and Logistics

• Annual salary: $205,000–$270,000 USD.
• Staff are currently expected to work from one of Anthropic's offices at least 25% of the time, although some roles may require more office time.
• Anthropic sponsors visas and makes reasonable efforts to support visa applications, with assistance from an immigration lawyer.
• Anthropic offers competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and office collaboration spaces.
