Senior Specialist, Vendor Audit and AI Enablement

About the Role

This role sits inside a leading energy infrastructure company and supports the planning and execution of a growing vendor audit program. The work centers on reviewing vendor invoices against commercial contract terms to find overbillings, recover overpayments, and strengthen vendor compliance across a large, complex supplier base. It is not an internal audit role; the day-to-day is hands-on with invoices, purchase orders, rate schedules, and financial data, in close partnership with Supply Chain, Finance, Legal, and Operations teams.

The ideal candidate is a seasoned external vendor auditor who is equally comfortable diving into large Excel data sets and engaging vendors directly on billing disputes. They are organized, curious, and self-directed, someone who proactively chases discrepancies to resolution rather than waiting to be pointed at a problem. Comfort supporting a parallel AI-enabled audit initiative, including data gathering, validation, and organization, will set a strong candidate apart.

Key Responsibilities

1. Review vendor invoices, purchase orders, change orders, timesheets, and rate schedules against commercial contract terms to identify billing discrepancies and non-compliance

2. Prepare and maintain Excel-based audit workpapers, reconciliation schedules, and supporting documentation that meet internal governance standards

3. Work directly with vendors to request documentation, clarify billing records, and support recovery of identified overpayments

4. Partner with Supply Chain, Finance, Legal, and Operations teams to resolve audit findings and coordinate recovery efforts

5. Extract and compile vendor data from SAP, SharePoint, and other internal systems; identify data gaps and organize large volumes of billing and contract documentation

6. Gather, validate, and organize high-quality data sets to support an AI-enabled vendor audit initiative and future automation capabilities

7. Contribute to audit reporting, recovery tracking, and program performance updates

8. Recommend and support continuous improvements to vendor audit processes, documentation, and operational efficiency

Required Skills & Experience

• Minimum 2 years of external vendor audit or invoice compliance experience

• University degree in Business, Finance, Accounting, Supply Chain, Commerce, Engineering, or a related discipline

• Demonstrated experience reviewing vendor invoices against commercial contract terms to identify overbillings and support financial recovery

• Strong Microsoft Excel skills including building, manipulating, and reconciling large data sets

• Experience extracting data from SAP or another ERP system

• Ability to interpret commercial contract terms including pricing schedules, rate structures, reimbursable cost provisions, and payment clauses

• Strong analytical, organizational, and problem-solving skills

• Excellent written and verbal communication skills in English

• Self-directed with the ability to manage multiple priorities in a fast-paced environment

Preferred Skills

• CPA, CIA, CISA, SCMP, PMP, or equivalent professional designation

• Experience with engineering and construction service contracts in the energy or oil and gas industry

• Experience working across Finance, Supply Chain, Legal, and Operations in a large organization

• Direct vendor engagement experience involving negotiation and overpayment recovery

• Experience supporting large-scale data collection and audit initiatives, including data preparation for automation or AI tools
