Transaction Monitoring Specialist

Location: Mexico City; Brazil Office Workplace: onsite About Unlimit Unlimit is the global financial infrastructure for the borderless agentic economy. Designed to bridge the gap between fragmented local markets and the future of autonomous commerce, Unlimit provides the programmable operating layer for the world’s most ambitious businesses. Through an integrated technology stack, the platform unifies global payment acceptance, programmable financial accounts, and digital asset rails into a singular financial layer. By mapping hyper-local payment ecosystems directly into its architecture, Unlimit enables businesses to move value and settle transactions instantly across continents.

With major hubs in London, San Francisco, Singapore, São Paulo, and Mexico City, Unlimit is building the infrastructure that makes global expansion a matter of code, not geography. The Transaction Monitoring Specialist sits at the intersection of financial crime detection and payment operations: monitoring transaction flows in real time, reconciling fiat and crypto movements as they settle, keeping liquidity available across banking rails, PSPs, exchanges and wallets, and acting as first responder when payment flows degrade. This is a hands-on operational role for someone comfortable making decisions quickly on live money movement, and equally comfortable documenting why those decisions were made. What You’ll Be Doing Monitor transactions and manage alerts : monitor fiat and crypto transactions in real time, investigate anomalies and suspicious activity, review alerts from transaction monitoring, sanctions screening, and blockchain analytics tools, and escalate cases to Compliance/MLRO when required. Perform payment reconciliation : reconcile internal ledgers with banks, PSPs, card acquirers, exchanges, and on-chain records; investigate and resolve breaks, unmatched items, duplicates, failed settlements, and other discrepancies. Manage reconciliation exceptions and customer-impacting issues : maintain the exception log, drive root-cause analysis and resolution, and support refunds, returns, chargebacks, misdirected deposits, and fund recovery. Manage liquidity and positions : monitor fiat and crypto balances across accounts and platforms, execute funding, rebalancing, and sweep instructions, and identify liquidity shortfalls, concentration risks, and settlement timing mismatches. Handle payment incidents and operational issues : detect, triage, escalate, and track incidents through resolution; monitor payment provider and blockchain network health and take mitigating actions when necessary. Maintain operational processes and partner relationships : keep runbooks, playbooks, checklists, and escalation procedures up to date and act as an operational point of contact for banking, PSP, and exchange partners. Prepare operational reporting : produce regular MI covering transaction volumes, success/failure rates, alerts, reconciliation breaks, incidents, and liquidity utilization, providing reliable data for Finance and Treasury. Drive continuous improvement: identify recurring manual work and operational issues, propose automation and control improvements, and work with Product and Engineering to implement and test process improvements. Qualifications You Will Bring 3 years of relevant experience in payment operations, transaction monitoring, AML/financial crime operations, settlement, or treasury within payments, fintech, crypto, or banking. Strong understanding of payment rails: SEPA / SEPA Instant, SWIFT, Faster Payments, local ACH schemes, card acquiring, and open banking.

Understanding of AML/CTF and sanctions requirements for virtual assets, including KYC/CDD, PEP and sanctions screening, source of funds, Travel Rule, SAR/STR escalation, MiCA, and local VASP requirements. Strong reconciliation and control mindset: comfortable working with ledgers, debits/credits, settlement cycles, cut-offs, and transaction discrepancies. Strong analytical and investigative skills: ability to work with raw transaction data, identify root causes, reach defensible conclusions, and clearly document findings. Advanced Excel/Google Sheets and preferably SQL: able to analyse large volumes of transaction and operational data. High attention to detail, sound judgement, and strong communication skills: able to work under time pressure, handle sensitive financial data with discretion, and communicate clearly in written and spoken English.
