About the role

Machine Learning Engineer responsible for real-time fraud detection platform, including model serving infrastructure, feature pipelines, deployment paths, and productionML systems with monitoring, drift detection, and on-call ownership.

Responsibilities

  • Build and own the model serving infrastructure, real-time inference, feature retrieval, and the latency budget that governs both
  • Build the deployment path our data scientists use to ship models themselves, including bring-your-own-model support for clients hosting their own
  • Own models in production: monitoring, drift detection, retraining, incident response, and the on-call rotation
  • Build and optimise the pipelines that turn raw device and behavioural signals into production-ready features
  • Work across Python and our Go backend to keep inference fast inside the request path
  • Build models yourself where it makes sense, roughly 20% of the role, and more if you want it
  • Champion testing, observability, security and compliance in a regulated environment

Qualifications

  • Experience building, not just using, model serving infrastructure
  • Production ownership of ML systems: paged when something broke, identified cause, and implemented fixes
  • Strong Python and solid software engineering fundamentals (testing, code review, CI/CD)
  • Comfort with Kubernetes, containers and a major cloud (GCP) plus infrastructure-as-code
  • Understanding of models to debug them (diagnose data vs feature pipeline vs model problems)
  • Experience building tooling for engineers or data scientists with self-serve vs guardrails
