RECENTLY POSTED

In short: A high-growth fintech is looking to bring on a Senior Data Scientist to build and ship production-grade scam intelligence that runs before payments clear. You’ll turn multi-source signals (transaction context, counterparty intelligence, behavioural patterns, unstructured evidence) into reliable, explainable risk decisions - under real-world constraints like latency, uptime, and auditability. About the company: The company is building a payment intelligence layer for banks - running real-time “investigations” on payments to provide rich context on the counterparty and situation. The goal: intercept scams while ensuring genuine payments flow smoothly. They’re early-stage, moving fast, and working on problems where correctness, security and reliability are non-negotiable. Who we’re looking for You’re a hands-on ML/AI builder who’s comfortable owning the full loop: data → modelling → deployment → monitoring → iteration. You care about practical decisioning (not just metrics), you’re thoughtful about trade-offs (customer experience vs protection), and you’re excited about building systems that are explainable and bank-grade. What you’ll do

  • Build and ship scam risk models and signals (typology classification, risk scoring, decision logic)
  • Engineer features across heterogeneous data: transaction context, behavioural sequences, counterparty signals, network/graph patterns, and unstructured evidence
  • Design calibrated outputs (scores + reason codes) that are actionable and explainable for banking workflows
  • Own evaluation end-to-end: leakage avoidance, cost-sensitive metrics, thresholding, phased rollouts, and post-incident learning
  • Productionise ML: packaging, deployment, monitoring, drift detection, and retraining strategies
  • Collaborate closely with backend/product teams to integrate intelligence into real-time payment flows
  • Work alongside agent/LLM workflows for evidence gathering and synthesis, while keeping the decision core predictable and auditable Must-haves:
  • Strong experience shipping applied ML into production (not just experimentation)
  • Strong Python + ability to write maintainable, tested code
  • Strong SQL + comfort working directly with messy, high-volume data
  • Solid modelling judgement: calibration, leakage, bias, thresholding, cost trade-offs, monitoring/drift
  • Experience building decisioning systems where reliability, latency, and explainability matter Nice-to-haves:
  • Experience in fraud/scams, payments, risk, trust & safety, AML, or adjacent domains
  • Familiarity with graph/network features and entity resolution style problems
  • Experience with MLOps tooling (model registry/MLflow, feature stores, orchestration)
  • Comfort with cloud-native/event-driven systems and working closely with platform/backend engineers
  • Experience integrating unstructured signals (text/embeddings/RAG style pipelines) into decision systems Why join
  • Work on a mission with real-world impact: stopping scams before money leaves
  • Build real-time, bank-grade ML systems with ownership end-to-end
  • Early team + high autonomy + meaningful technical decisions
