Senior Machine Learning Engineer

Senior Machine Learning Engineer @ Berry AI Senior Machine Learning Engineer Location Taipei - Neihu Employment Type Full time Location Type Hybrid Department Engineering Berry AI builds AI-powered operations platforms for QSR restaurants — drive-thru analytics, loss prevention, and store management tooling deployed at thousands of locations across the US — and growing. Computer vision sits at the core of what we ship. We're hiring a Senior ML Engineer to own model development end-to-end and turn business requirements into production systems. What you'll work on - Drive iteration across our AI/ML stack — object detection and tracking, person/vehicle Re-ID, and video understanding running on edge. - Build efficient algorithms for resource-constrained hardware — implement lightweight architectures and optimization techniques within latency and compute budgets. - Turn business asks into algorithmic problems — design the metrics, run experiments, and drive each iteration with ablation studies and error analysis. - Partner with product engineers to ship and monitor ML systems in production — deployment paths and feedback loops that catch data drift and failure modes. - Improve data and labeling quality — sampling strategy, annotation guidelines, and tooling that keeps a long-lived dataset healthy. You're a strong fit if you have - 5+ years building production ML systems, with deep hands-on experience in computer vision, especially in object detection and multi-object tracking. - Strong ML/DL fundamentals — statistics, classical methods, and modern deep learning, with a clear grasp of model internals, training dynamics, and common failure modes. - Python and DL framework experience — PyTorch or TensorFlow, including custom training loops, distributed training, and end-to-end model debugging. - A track record of driving research independently — picking the metric, designing the experiment plan, and interpreting noisy results honestly. - Producti
