AI Blue-Green Model Deployment Engineer

Aurora Vestergaard

Full-time · Job · Berlin

About the role

Deploying a new model version shouldn't feel like defusing a bomb. Blue-green deployment eliminates the risk: the new model runs alongside the old one, receives a small percentage of traffic, and only takes over fully once metrics confirm it's performing at least as well. If anything goes wrong, traffic reverts to the old model in under 30 seconds. You'll build the deployment orchestration that manages this process: spinning up the new model environment, configuring traffic splitting, monitoring comparison metrics in real time, and automating the promotion or rollback decision. The system needs to handle 340 models across 28 clients, each with different SLOs, comparison metrics, and rollback triggers. The deployment platform team is four engineers. As the junior engineer, you'll focus on the traffic management and metric comparison layers. Your senior teammates handle the underlying Kubernetes orchestration; you handle the deployment workflow that decides when it's safe to proceed.

  • Implement traffic splitting with configurable percentages
