Audit Specialist

Responsibilities

Must Have: internal audit, financial statement audit, or SOX compliance backgrounds

This role will be posted and sourced under the title 'Vendor Audit Specialist.' Applicants from internal audit, financial statement audit, or SOX compliance backgrounds without invoice-level vendor billing experience are not a match for this role and will not be shortlisted.

The Vendor Audit Specialist supports the planning and execution of TC Energy's expanding vendor audit program. This role is fundamentally about reviewing vendor invoices against commercial contract terms to identify over billings, and working with vendors and internal stakeholders to recover over payments. This is not an internal audit role — candidates with exclusively internal audit backgrounds will not be considered.

Two positions are available to address a capacity gap created as existing team members are partially redeployed to support development of a new AI-enabled audit capability. The successful candidates will maintain audit execution and data gathering activities during this transition period — gathering large volumes of vendor data from internal systems and directly from vendors to support both ongoing audits and the data foundation the new tool requires.

The work is highly manual and data-intensive. The majority of time is spent in Excel — building spreadsheets, manipulating data sets, reconciling billing records against contract terms. Candidates who do not enjoy this type of work should not apply.

• Review vendor invoices, purchase orders, change orders, timesheets, and rate schedules against contract terms to identify over billings, non-compliance, and billing discrepancies.
• Build and maintain Excel-based audit work papers, 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 over payments through negotiation and follow-up.
• Collaborate with internal stakeholders across Supply Chain, Finance, Legal, and Operations to resolve audit findings and coordinate recovery actions.

• 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.

• 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.

• University degree in Business, Finance, Accounting, Supply Chain, Commerce, Engineering, or a related discipline. A minimum of a university degree is required; candidates without post-secondary credentials will not be considered regardless of experience.
• Relevant professional designation considered an asset: CPA, CIA, CISA, SCMP, PMP, or equivalent.

• Vendor audit or invoice compliance experience — reviewing vendor invoices against commercial contract terms, identifying over billings, supporting financial recovery. This is the primary experience filter. Candidates with this background are prioritized regardless of industry.
• 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…
