📋 Description

• Build, train, and optimize computer vision models for image classification, face liveness detection, and presentation attack detection (PAD) / anti-spoofing • Work on real-world identity verification and biometric authentication problems, improving model performance on noisy, adversarial inputs such as spoofed images, replay attacks, deepfakes, and synthetic media • Design and run experiments to improve model accuracy, recall, robustness, and fraud detection performance using techniques such as augmentation, class balancing, architecture tuning, and hard-negative mining • Design, train, and improve deep learning models (e.g., CNNs, Vision Transformers, and foundation models), including loss function design, hyperparameter optimization, and performance tuning on large-scale image datasets • Prepare and curate large, noisy datasets, including data ingestion, validation, cleaning, deduplication, labeling strategies, and dataset QA to improve model reliability and generalization • Develop evaluation protocols and success metrics that balance fraud detection effectiveness, false acceptance rates, false rejection rates, and overall business impact • Develop production-grade training and inference pipelines on AWS with strong reproducibility, monitoring, observability, and cost controls • Productionize models as resilient Python services and libraries; collaborate with platform teams to optimize APIs, latency, scalability, and operational reliability • Contribute to the evolution of our Identity Verification (IDV) platform by modernizing legacy components and improving model performance, maintainability, and modularity • Partner closely with Product, Customer Success, Fraud, and Platform Engineering teams to ensure ML solutions meet privacy, compliance, security, and reliability requirements • Support and mentor other engineers through design reviews, code reviews, experimentation best practices, and knowledge sharing • Research and evaluate emerging techniques in face liveness detection, presentation attack detection (PAD), deepfake detection, biometric authentication, and adversarial machine learning to strengthen our fraud prevention capabilities

🎯 Requirements

• Bachelor's degree in Computer Science, Electrical Engineering, Computer Engineering, or a related technical field (or equivalent professional experience) • 5+ years of experience in applied machine learning, computer vision, or ML engineering with strong software engineering fundamentals (or equivalent combination of education and experience) • Strong Python programming skills and experience building production-quality machine learning systems • Experience developing and deploying computer vision models for image classification, detection, segmentation, or related image-based learning tasks in production environments • Hands-on experience designing, training, evaluating, and optimizing deep learning models using PyTorch or TensorFlow • Strong computer vision background, including experience with CNNs, Vision Transformers, foundation models, image processing, and feature extraction techniques • Experience working with large-scale image datasets, including data preprocessing, augmentation, labeling strategies, dataset QA, and model evaluation • Understanding of model performance tradeoffs, including precision, recall, false positive rates, false negative rates, and robustness in real-world environments • Proven ability to build reliable training and inference pipelines and collaborate on production deployment of machine learning systems • Strong communication and collaboration skills with the ability to work effectively across engineering, product, fraud, operations, and platform teams • Experience evaluating and improving model performance in adversarial, noisy, or highly imbalanced datasets

🏖️ Benefits

• Wellness: Universal, supplemental, and private healthcare plan choices based on country specifics • Financial future: retirement/pension plan contributions, MTK stock plan participation • Income protection: life event & disability coverage • Paid time off: generous annual leave, company holidays, volunteer time off • Learning: e-learning license, tuition reimbursement, hackathons • Home office setup allowance • Additional/optional benefits: pet insurance, identity theft protection, legal assistance
