## About the role

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.

## What they're looking for

- Experience building, not just using, model serving infrastructure
- Production ownership of ML systems: you've been paged when something broke, you found out why, and you changed something so it didn't happen again
- Strong Python, and solid software engineering fundamentals, testing, code review, CI/CD, the discipline that makes a platform other people can rely on
- Comfort with Kubernetes, containers and a major cloud (we're mostly GCP), plus infrastructure-as-code
- Enough understanding of models to debug them. You don't need to have trained one recently, but when precision drops you should know the difference between a data problem, a feature pipeline problem, and a model problem
- Experience building tooling other engineers or data scientists actually use, and the judgement to know what should be self-serve and what shouldn't
