Finance Systems Engineer, Tax

About the Role

Anthropic's Tax Technology function, within Finance Systems, is responsible for systems that ensure all revenue and purchasing transactions are bookable, taxable, and auditable. We seek a tax technologist who understands tax systems and builds integrations, tooling, and production code to connect them with Anthropic's billing, ERP, and data warehouse systems. You will work across indirect tax, corporate income tax and provision, withholding tax, R&D credits, and transfer pricing. As a foundational hire on a small team, you will collaborate directly with the Tax Technology Lead and cross-functional partners in Tax, Data Science, Billing Engineering, and Product. You will be the key technical resource for Anthropic tax technology, building and hardening tax-specific tooling and audit-ready evidence pipelines to support business growth. Future projects include leveraging Claude to automate tax work end-to-end and developing high-impact, user-friendly internal products for the Tax team.

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, encompassing 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 withstand external audit.
• Design and build tooling that applies Claude to tax work and provides non-technical tax colleagues with self-serve access to data, calculations, and evidence.
• Serve as the technical owner for vendor implementation handoffs, actively participating during the build and remaining accountable post-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 emerge.

Requirements & Tech Stack

• Hands-on experience building or owning production integrations against billing platforms, ERPs, or enterprise tax or finance systems.
• Tax-systems fluency in at least one domain (indirect tax engines, corporate tax provision or compliance tooling, withholding, research credit, or transfer pricing systems), acquired from 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 the tax team without an intermediary.

Qualifications

• 7+ years in tax technology, finance systems engineering, or a closely related field.
• Experience owning changes within a shared production codebase alongside a product engineering team.
• Warehouse and analytics-engineering skills such as dbt, BigQuery, or comparable.
• Breadth across multiple tax domains, including indirect (sales/use, 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.
• Record of novel AI applications for foundational tax tasks or problems.
• Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience.
• Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience.

Compensation

• Annual Salary: $205,000—$270,000 USD

Logistics

• Location-based hybrid policy: Expect to be in one of our offices at least 25% of the time. Some roles may require more time in offices.
• Visa sponsorship: Available, with a commitment to making reasonable efforts for offers.
