Machine Learning Engineer

As a Machine Learning Engineer at Sardine, you'll own the systems that make real-time fraud detection possible. Our data science team builds custom models for our clients, you build and run the platform they deploy onto, and the low-latency serving path those models score on. Sardine scores millions of sessions in real time from hundreds of device and behavioural signals, inside a sub-250ms budget. That constraint shapes everything: how features are computed and served, how models are deployed and rolled back, how quickly you know when something has degraded. You'll be the person who figures out why a model broke.

• 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:
