What you'll be doingOwn the Payments Lifecycle: Run end-to-end global payment operations as well as crypto settlement, bridging, and custodian movements.
Execute Accounts Payable & Payroll: Prepare, review, and release accounts payable runs and payroll disbursements across entities.
Strengthen Crypto Controls: Oversee hot/cold wallet movements, whitelisting, pre-sign review, chain-to-ledger reconciliation, and on-chain parity checks; treat crypto with the same rigour as a regulated fiat .
Reconcile & Resolve Exceptions: Monitor queues across rails, investigate failed and stuck transactions, resolve breaks between rail ↔ ledger ↔ custodian ↔ bank, and enforce cut-off discipline.
Improve the Internal Treasury System: Act as the operational voice shaping our in-house Treasury payment tooling - requirements, UAT, business readiness, and change control, partnering with product and engineering.
Oversee Automated Flows: Monitor payment provider integrations, catch drift early, and prioritise the automation backlog with engineering.
Govern Procedures: Own procedure documentation, periodic reviews, and change control so controls stay current with regulatory and business change.
Report & Measure: Produce operational reports on settlement timeliness, funding utilisation, break rates, and control effectiveness; surface insights that drive decisions.
Escalate & Investigate: Spot risk early, escalate promptly to contain loss, and lead post-incident reviews with clear root cause and durable fixes.
Partner Cross-Functionally: Be the first point of contact for business, technology, risk, compliance, and finance; align stakeholders and drive timely resolution.
What You'll Need
3+ years in payments operations, treasury operations, or settlements at a bank, fintech, exchange, or payments provider.
Strong working knowledge of fiat payment rails and the operational mechanics of reconciliation, exception handling, and cut-offs
Sharp control instincts: you've owned procedure documents, change control, and audit-ready evidence, and you can spot a weak control from a mile away.
Experience executing accounts payable and / or payroll disbursements at scale, including multi-entity and multi-currency flows.
High attention to detail and accuracy in processing, reconciliation, and control activities.
Track record of delivering automation and process re-engineering that measurably improved speed, accuracy, or scalability
Nice to Have
Direct experience operating LATAM rails (SPEI, PIX, PSE, CBU) inside a regulated entity
Hands-on experience with crypto operations - custody, wallet movements, bridging, chain rebalancing, and on-chain reconciliation with a security-first mindset
Experience with a Treasury Management System and / or building an in-house equivalent
SQL for querying payment, ledger, and operational data - you don't wait for someone else to pull the numbers
Spanish and/or Portuguese proficiency
