Senior Vendor Audit Analyst

On behalf of our oil & gas client, Vaquarii is seeking a Senior Vendor Audit Analyst for a 6-Month Contract with a high possibility of extension or conversion to full-time employment The perfect candidate will be reviewing vendor invoices against commercial contract terms to identify overbillings, and working with vendors and internal stakeholders to recover overpayments. Services would be carried out though a Hybrid Work Schedule from their downtown Calgary headquarters.

Responsibilities:

Vendor Audit Execution

• Review vendor invoices, purchase orders, change orders, timesheets, and rate schedules against contract terms to identify overbillings, non-compliance, and billing discrepancies.
• Build and maintain Excel-based audit workpapers, data sets, and reconciliation schedules to document findings and support recovery.
• Support development and execution of the vendor audit plan – scoping audits, gathering supporting documentation, and maintaining audit trails per internal governance standards.
• Engage directly with vendors (experienced candidates) to request documentation, clarify billing records, and support recovery of identified overpayments through negotiation and follow-up.
• Collaborate with internal stakeholders across Supply Chain, Finance, Legal, and Operations to resolve audit findings and coordinate recovery actions.

Data Gathering and Audit Scope Expansion

• Extract and compile vendor data from internal systems (SAP, SharePoint, ACP) and through direct vendor outreach to build the data foundation required for expanded audit coverage.
• Support planning activities for a significantly expanded audit scope — identifying data gaps, coordinating data requests, and organizing large volumes of billing and contract documentation.
• Contribute to audit reporting and management updates tracking recovery value, findings, and program performance against signed targets.

AI Initiative Support

• Gather and organize the large, clean data sets required by the vendor audit AI tool being developed by the existing team. This is a data preparation and validation function — these roles are not involved in tool development, configuration, or prompt engineering.
• Provide subject matter input on audit findings and data patterns to support tool refinement as directed.

Must Have Skills:

1. University degree in Business, Finance, Accounting, Supply Chain, Commerce, Engineering, or a related discipline.
2. Relevant professional designation considered an asset: CPA, CIA, CISA, SCMP, PMP, or equivalent.
3. Vendor audit or invoice compliance experience – reviewing vendor invoices against commercial contract terms, identifying overbillings, supporting financial recovery.  
4. Experience with engineering and construction services contracts in oil and gas or energy is the preferred background. Vendor audit experience from other industries with comparable contract complexity is acceptable – skills are transferable.
5. Project management and organizational experience in a fast-paced, multi-stakeholder environment.
6. Experience working cross-functionally across Finance, Supply Chain, Legal, or Operations in a large organization.
7. Candidates without vendor audit experience will be considered if they demonstrate exceptionally strong Excel proficiency, analytical capability, organizational skills, and the ability to learn a specialized field quickly.

Nice to Have Skills:

1. Excel proficiency at a strong working level – comfortable spending the majority of the workday building, manipulating, and reconciling large data sets. This is the single most important technical requirement.
2. SAP or ERP navigation ability for internal data extraction. Orientation will be provided; candidates must get up to speed quickly.
3. Ability to interpret commercial contract terms: pricing schedules, reimbursable cost provisions, rate structures, and payment clauses.
4. Strong analytical and problem-solving skills with high attention to detail and accuracy.
5. Clear written and verbal communication – ability to document findings precisely and interact professionally with vendors and senior internal stakeholders.
6. Self-directed and highly organized. This team moves quickly and cannot carry individuals who require close supervision.
7. Available through the summer months without extended leave of absence, this project launches immediately and requires consistent availability during the critical ramp-up period.

Job Location:

• Downtown Calgary, Alberta
• Hybrid Work Schedule (Mon/Tue/Thu in office)

WHAT SUCCESS LOOKS LIKE

• At the end of the contract, a successful candidate will have contributed directly to the team’s signed cost recovery targets and the number of audits completed.
• These are the metrics the program is measured against.
• Candidates who perform well have a realistic path to contract extension or conversion to full-time employment – approximately 70–80% of the current team joined as contractors.
