Position Overview

TRP has a current vacancy for a Senior Accounts Payable/Project Accountant that will provide hands-on accounting and finance operations support to the Finance and Admin Lead. The role focuses on account reconciliations, affiliate and partner account tracking, investigation and resolution of accounting and cost issues, and ongoing audit support, helping maintain accurate financial records and reliable project cost reporting. The role maintains audit-ready reconciliations and supporting records throughout the year, coordinates outstanding documentation and follow-up actions, and supports improvements to internal controls and accounting procedures. Technical accounting conclusions and matters requiring management approval are escalated to the Finance and Admin Lead.

Key Responsibilities

General Finance Support

• Provide hands-on support to the Finance and Admin Lead across day-to-day finance activities, information requests, and issue resolution. Investigate discrepancies, coordinate corrective actions with relevant teams, and track outstanding matters through to resolution, escalating issues and competing priorities as needed.
• Prepare and maintain financial schedules, reconciliations, and supporting records for management review, reporting, and month-end support. Investigate differences, follow up on aged outstanding items, and coordinate required adjustments with the accounting team.
• Maintain affiliate and partner tracking schedules covering invoices, recharges, payments, balances, and outstanding items.

• Own the end-to-end tracking and coordination of all supporting documentation provided to the client for monthly cost-plus billings. Maintain a complete, traceable register linking billed costs to supporting records and tracking submission dates, client queries, outstanding requirements, and resolution status. Coordinate with relevant teams (procurement, subcontract, cost control, AP) to obtain missing evidence, retain a clear record of all submissions and responses, and follow outstanding items through to closure, escalating delays or unresolved issues to the Finance and Admin Lead.
• Provide ad hoc financial analysis, tracking reports, documentation, and finance-related administrative support as assigned by the Finance and Admin Lead. Coordinate information requests across teams, maintain clear records of actions and decisions, and support practical improvements to finance and AP workflows.

Compliance & Audit Support

• Coordinate ongoing internal and external audit requests under the direction of the Finance and Admin Lead. Prepare audit schedules, reconciliations, cost breakdowns, transaction listings, and supporting documentation; maintain a request tracker; and follow up with relevant teams to resolve missing evidence and outstanding queries within agreed deadlines.
• Perform periodic reviews of project transactions to assess compliance with approval limits, delegated authorities, procurement procedures, and financial control requirements.
• Support the implementation of improved internal controls, standard operating procedures, and documentation requirements to reduce audit findings and recurring control deficiencies.
