8d•$190,000 - $230,000•Hybrid

About The Position

Anthropic is seeking a Vendor Admin Lead to manage vendor master data for its global Finance Operations team. This role is crucial for ensuring the accuracy and integrity of vendor information, including onboarding, bank-detail verification, supporting documentation vetting, data quality, and associated controls. The position is designed to be separate from invoice processing and payments, focusing solely on controlling vendor records and bank details. The Vendor Admin Lead will own the SOX controls related to vendor master data and contribute to designing the access model to maintain these controls. This is a unique opportunity to build a vendor-master function from scratch, leverage process automation with AI tools like Claude, and support Anthropic's mission of making AI safe.

Requirements

7+ years in vendor master or AP operations with 3+ years of ownership.
Owned a vendor master in an ERP end to end — process, controls and data — across multiple entities and countries.
Hands-on experience verifying bank details and preventing payment fraud: bank letters, independent callbacks, BEC red flags, international bank formats.
Experience with vendor tax documentation: W-9/W-8 validation, TIN matching, VAT/GST IDs, 1099 flagging.
Working knowledge of procure-to-pay controls — segregation of duties, maker-checker, change logs, audit evidence — and have performed or owned a SOX control.
Led a vendor data cleanup, consolidation or ERP migration and can show the outcome.
The confidence to hold the line with requesters, vendors and senior stakeholders under time pressure while staying clear and helpful.
Strong Excel or Google Sheets skills with large datasets (dedupe, lookups, reconciliations) and exceptional attention to detail.

Nice To Haves

Workday Financials vendor management, and experience with Zip, Coupa or a similar procure-to-pay platform.
SOX experience at a public company or one preparing to go public.
Experience supporting APAC and EMEA vendors in a high-growth, multi-entity company.
Experience designing or reviewing ERP security roles with a systems team.
Comfort using AI tools to automate validation, follow-ups and reporting.

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 escalate 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 checklists, requester guidance and service levels.
Serve as the vendor-data expert through process migrations, including data conversion and post-migration fixes.
Partner on automation: AI-assisted intake validation, document extraction, bank-format checks and a vendor self-service portal.
Report monthly on onboarding volume, cycle time, bank changes, exceptions and data quality, and use the data to improve the process.
