Vendor Master Data Specialist | 3-month Inside IR35 contract

I’m currently partnering with a fast-growing technology business, that is undergoing significant finance transformation, with a focus on process automation and improving data quality.

They are looking for a Vendor Master Data Specialist to support a large-scale data cleansing project across their supplier database.

With approximately 2,000 vendors on their system, 1,300 of which have been uploaded with incomplete information, this individual will play a key role in ensuring supplier records are accurate, complete and fit for purpose.

Key responsibilities:

  • Lead the clean-up and validation of vendor master data across approximately 2,000 supplier records.

  • Proactively contact vendors via outbound calls and emails to obtain missing information.

  • Review, verify and update supplier records, ensuring accuracy and completeness.

  • Identify and resolve data discrepancies, inconsistencies and duplicate records.

  • Support the wider finance team’s process automation and data improvement initiatives.

What we’re looking for:

  • Previous experience in vendor master data, accounts payable, finance operations or data cleansing.

  • Excellent communication skills – someone confident picking up the phone, chasing information and building rapport with suppliers.

  • Exceptional attention to detail and a methodical, organised approach.

  • A proactive, hands-on individual who can work independently and manage a high volume of supplier records.

  • Comfortable working in a fast-paced, evolving scale-up environment.
