Design and develop computer vision models and pipelines, contributing to biometrics use cases such as face detection, quality assessment, and recognition
Collaborate on benchmarking of models across datasets and operating conditions
Train and optimize models using PyTorch, TensorFlow, and/or JAX
Contribute to end-to-end ML pipelines, from data ingestion to deployment. Help design automated pipelines (Airflow) for data ingestion and cleaning.
Production Engineering: Optimize models for low-latency inference (quantization, distillation, TensorRT/ONNX) and support deployment on AWS.
Collaborate with and mentor ML engineers, and contribute to technical best practices across the Computer Vision team.

What We’re Looking For

Experience: 5+ years of industry experience in Machine Learning with a focus on Computer Vision (e.g., image classification, object detection, segmentation, image quality, generative models)
Strong Computer Vision fundamentals
Fairness & Ethics: Awareness of algorithmic bias and willingness to learn domain-specific fairness practices
Strong Engineering: Strong proficiency in Python (Pillow, OpenCV, PyTorch, etc). You write clean, modular, production-ready code
Systems Architecture: Experience designing or contributing to ML pipelines and familiarity with orchestration tools like Airflow
Cloud Native: Experience with GPU-based training and deploying ML services on AWS

Nice to Have

Research Publications in top computer vision venues (CVPR, ICCV, ECCV)
Large Scale Search: Familiarity with vector databases and ANN search
Synthetic Data: Experience with GANs or diffusion models for data augmentation
Mobile/Edge Experience: CoreML, LiteRT, and/or TFLite
Familiarity with privacy, security, and compliance considerations in sensitive ML applications
