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 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

Minimum qualifications

• 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

Preferred qualifications

• 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

The annual compensation range for this role is listed below.

For sales roles, the range provided is the role’s On Target Earnings ("OTE") range, meaning that the range includes both the sales commissions/sales bonuses target and annual base salary for the role.

Annual Salary:$190,000—$230,000 USD

Logistics

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

Minimum years of experience: Years of experience required will correlate with the internal job level requirements for the position

Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices.

Visa sponsorship:We do sponsor visas! However, we aren't able to successfully sponsor visas for every role and every candidate. But if we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this.

Not all strong candidates will meet every single qualification as listed. Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you're interested in this work. We think AI systems like the ones we're building have enormous social and ethical implications. We think this makes representation even more important, and we strive to include a range of diverse perspectives on our team.

How we're different

We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills.

The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences.
