• Tune and maintain risk-scoring parameters, transaction-monitoring rules and screening match thresholds to reduce false positives while preserving coverage - and document every change with audit-ready evidence.
• Analyse alert output and case feedback to recommend, test and implement threshold and logic changes; run above-the-line / below-the-line testing and periodic tuning cycles.
• Translate emerging money-laundering, sanctions-evasion and fraud typologies into detection scenarios and rules, with clear written rationale and coverage assessments against LemFi's cross-border corridors.
• Tune name and entity matching logic for sanctions, PEP and adverse-media screening across onboarding and ongoing checks; maintain customer and transaction risk-scoring segmentation aligned to risk appetite.
• Build and interpret MI on alert volumes, false-positive rates and conversion to cases and SARs; produce tuning reports that leadership, auditors and regulators can rely on.
• Partner with Product and Engineering to specify changes, with Investigations for feedback loops, and with Compliance and the MLRO for policy and risk-appetite alignment.
• Support internal audit, model-validation exercises and regulatory exams with a maintained, evidence-backed change log.

Your experience

• Around 3 to 5 years in financial crime - transaction monitoring, sanctions screening and/or fraud - at a bank, fintech, payments provider or PSP.
• Hands-on experience configuring or tuning TM and/or screening systems: rules, scenarios, matching logic or thresholds, not just reviewing outputs.
• Solid working knowledge of AML/CTF, sanctions and fraud typologies and the regulatory expectations around monitoring and screening governance.
• Comfortable working with data: reading and interpreting alert and transaction data, slicing it in spreadsheets, and using basic SQL to pull what you need (or a clear and demonstrated appetite to build that skill quickly).
• Strong analytical and documentation skills - able to evidence and defend a tuning decision to an auditor or examiner in plain language.
• A clear communicator who can translate between risk and systems, working across compliance, product and engineering without losing accuracy.

Nice to have

• Experience in cross-border remittance, multi-corridor payments or a PSP operating across multiple jurisdictions.
• Exposure to specific TM or screening vendors, and/or familiarity with Python or analysis notebooks.
• Experience directly supporting internal audits or regulatory examinations.
