Job description

Referment is working with a regulated payments business providing business accounts and international payment services across multiple currencies and jurisdictions. It is looking for a Treasury Solutions Engineer to connect the operational work of moving money with the systems and data needed to keep it accurately reconciled and reportable.

You’ll sit between Finance and Technology, owning day-to-day treasury integrity and ledgers across group entities. The balance is genuinely hands-on: you might investigate a failed payment, manage liquidity between banking partners or write the reconciliation logic that prevents the same issue recurring.

This role needs more than treasury knowledge or technical skills in isolation. You’ll work directly with banking partner and internal APIs, understand how payment flows affect the ledger, and turn that information into reliable reconciliations and reporting. Finance will be a close partner on month-end and audit work, while Technology will support platform improvements and issues beyond your own integrations.

The Role

• Maintain and reconcile multi-currency ledgers across live business accounts and banking rails, investigating discrepancies and ensuring financial records remain accurate.
• Manage cash movements, liquidity and settlement timing between banking partners.
• Reconcile safeguarded accounts daily under applicable payment services requirements, including PSR 2017.
• Own SEPA and ECB settlement operations across EUR flows, covering cash management, reconciliation and issue resolution.
• Reconcile customer contracts against fee schedules and correct billing discrepancies before they reach customers.
• Build and improve treasury reporting on cash positions, safeguarding, banking partner performance and fee reconciliation using API data and analysis tools.
• Resolve failed payments and support new banking partner integrations from testing through go-live.

What We’re Looking For

• At least five years in treasury, banking operations or fintech reconciliation at scale, including regulated payments or e-money experience.
• Strong multi-currency ledger, daily reconciliation, FX operations and liquidity management knowledge.
• Working knowledge of safeguarding under PSR 2017 or equivalent EMR 2011 requirements.
• A technical or engineering background with practical REST API and JSON skills, including working directly with endpoints without relying on engineering for every task.
• Confidence with SQL, Power BI and advanced Excel, and the ability to resolve operational and technical issues with banking partners.

Desirable Experience

Python would be useful. Direct SEPA operations or ECB settlement experience is particularly valuable.

This could suit a technically capable treasury or reconciliation specialist, or a finance systems professional with substantial regulated payment operations experience.
