Job description

About Anthropic

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

About the role

We are looking for a Vendor Admin Lead to own vendor master data for our global Finance Operations team. Reporting to the Director of Global Accounts Payable, you will be the single point of accountability for who our vendors are and get paid: onboarding, bank-detail verification, supporting documentation vetting, data quality and the controls around all of it. Anthropic's vendor base is growing quickly across the US, Europe and Asia-Pacific, and a clean, verified vendor data is what keeps a fast-growing company scale with the necessary controls.

This role is deliberately separate from invoice processing and payments. You will control vendor records and bank details; you will not book invoices or move money. That separation is the point of the role, and you will own the SOX controls that enforce it and help design the access model that keeps it that way.

This is an opportunity to build a vendor-master function from the ground up and leverage process automation with Claude while supporting the team making AI safe.

Responsibilities

Supplier onboarding

• Run intake for every new vendor and payee: validate completeness, collect and verify supporting documentation, and enable records in the ERP backbone system against agreed service levels

• Validate supporting documents; set 1099-reportable and tax flags correctly

• Confirm third-party risk and restricted-party screening before activation

• Set up one-time and non-vendor payees with the right record type rather than forcing them through full onboarding

• Partner with TPRM and IA teams on control requirements and continuous process improvement

• 1099 annual reporting

Bank details and fraud prevention

• Own every bank-detail setup and change; validate against a bank letter on letterhead or an approved equivalent (void checks, etc.)

• Run independent callbacks per policy using contact details sourced independently of the request, and record the evidence

• Validate international bank formats and addresses (IBAN, SWIFT/BIC, ABA, SEPA, BSB, IFSC, Japanese bank/branch codes)

• Identify and elevate business-email-compromise attempts and other payment-fraud red flags

Data quality and maintenance

• Maintain vendor structure: parent/child and remit-to relationships, entity and country records, contacts and payment terms

• Lead vendor consolidation: eliminate duplicate vendors and bank accounts, execute merges and inactivations in batched, logged, reviewed changes

• Run periodic health reviews for dormant vendors, stale bank letters, missing tax forms and incomplete records; drive 1099 and TIN readiness for year-end

• Own periodic vendor deactivation campaigns

Controls and audit

• Own the vendor-master SOX controls as the named control owner: maker-checker on every create and change, change-log review, evidence retained on every record

• Prepare the periodic review of bank-detail changes paid, and address Internal Audit and external auditor requests

• Partner with Finance Systems to design and maintain ERP security roles so vendor master, invoicing and payments stay separated

• Flag any suspicious vendor set-up activity through the appropriate channels

Process, systems and improvement

• Own vendor-master documentation, intake ch
