Treasury Accounting Senior Manager/ Manager (Bangkok based, relocation provided)

The Opportunity 

We are looking for an FX Controller to join our Finance team in Bangkok. This role is ideal for an experienced accounting professional with strong technical knowledge of foreign exchange, derivatives, hedge accounting and financial controls in a complex multinational environment. 

You will own the accounting and controllership framework for foreign-currency transactions and exposures across multiple entities, currencies and jurisdictions. This includes FX revaluation, realized and unrealized gains and losses, derivatives, hedge-related accounting, foreign-currency intercompany transactions, exchange-rate governance and the reconciliation of Treasury systems to the general ledger. 

You will be responsible for ensuring that FX accounting outcomes are complete, accurate, explainable and compliant with applicable accounting standards and internal policies. You will also provide clear analysis of material FX movements, identify unexpected exposures or accounting outcomes, and coordinate their resolution with Treasury, Controllership, Tax, Finance Systems and other Finance teams. 

Beyond close and reporting ownership, you will help establish a scalable FX accounting operating model. This includes strengthening controls, improving exposure and hedge visibility, automating reconciliations and ensuring that the economic intent of Treasury activity is reflected appropriately in the financial statements. 

This is a high-impact role for someone who enjoys combining technical accounting, FX and derivatives expertise, financial controllership, data analysis and cross-functional leadership.

• Ensure approved exchange rates are applied consistently, including spot rates, month-end rates, average rates, historical rates and fixed intercompany rates where required. 

• Challenge unexplained or unhedged exposures and work with Treasury and Finance teams to determine whether they arise from genuine economic positions, timing differences, missing transactions or accounting errors. 

• Establish investigation and escalation thresholds for material FX differences and unresolved reconciliation items. 

• Ensure significant FX-related balance-sheet accounts are reconciled, reviewed and signed off within the close timetable. 

Exchange-Rate Governance and Data Quality 

• Own or oversee the governance of exchange rates used in ERP, Treasury, consolidation and reporting systems. 

• Validate that approved rates are complete, accurate, timely and consistently applied across entities and accounting processes. 

• Monitor interfaces between systems, market-data sources, ERP platforms and relevant tools. 

• Investigate differences caused by incorrect rates, stale data, currency mapping or system configurations. 

• Partner with Finance Systems and Treasury teams to improve the reliability and traceability of data. 

• Maintain appropriate evidence and approval records for rates, valuations, adjustments and system-generated entries. 

Financial Reporting and Management Analysis
