AI Engineer - Computer Vision in Mysore, भारत

Work Description :- Train and fine-tune instance segmentation and object detection models (Mask R-CNN, YOLO-family) to detect irrigation and landscape symbols across mixed symbol libraries, varying scales and rotations.- Build the hatch and bed-line segmentation pipeline that measures areas for sod, seed, mulch, paving and similar, including cases where identical hatches carry different labels or appear nowhere in the legend.- Design the tiling and preprocessing strategy for large-format plan sheets, and own the trade-off between tile count, detection recall and inference cost.- Implement calibrated confidence scoring, and the "unknown - needs review" path so unfamiliar symbols surface instead of being misclassified with false confidence.- Run the three fine-tuning rounds : train, evaluate against acceptance criteria, error-analyse which classes underperform, and carry a written remediation plan into the next round.- Deploy models to Amazon SageMaker asynchronous endpoints with scale-to-zero, and keep releases immutable and version-tagged so any release can be rolled back.- Work with the QA engineer on per-class acceptance measurement, no-regression checks and the calibration and held-out https://jobeax.com/link/TvvvAMRHuWyhd20k required : - Strong Python, and production experience with PyTorch on detection or segmentation tasks - not just notebook experiments.- Hands-on work with Mask R-CNN, YOLO, Detectron2 or similar, including training on custom datasets and diagnosing class-level failure.- OpenCV and image preprocessing : tiling, rotation, scale normalisation, morphology.- PDF and raster handling at scale (PyMuPDF, pdf2image, Poppler, Pillow).- A working understanding of detection metrics - mAP, IoU, precision and recall per class - and why aggregate accuracy hides per-class regression.- AWS : S3, SQS, and either SageMaker or comparable managed https://jobeax.com/link/ejPw2GxN6D9Ckh0T to have :- Experience reading engineering, architectural or CAD-derived drawings.- Active learning or human-in-the-loop correction pipelines.- Model optimisation for inference: TensorRT, ONNX, quantisation.- Annotation tooling and labelling workflow design.
