Financial Crime Analyst

• The Fincrime Product team builds and maintains the platform that protects LemFi and its customers from sanctions breaches, money laundering and fraud
• As our Rules Modeller / FinCrime Analyst, you are the bridge between financial-crime risk and the systems that detect it: you own the tuning, thresholds and risk-scoring logic that decide what gets flagged, and you own the evidence that proves those decisions are sound
• This is a domain-led role on a small, senior team
• You will spend your time in typologies, alert data and detection logic - reducing false positives without letting real risk slip through - working closely with Compliance, Investigations, Product and Engineering
• Your tuning directly shapes both our operational cost and our regulatory posture across more than 21 countries and dozens of corridors
• 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
