Innovation: Opportunity to experiment with cutting-edge ML and GenAI technologies in production settings. Collaboration: Work alongside backend, platform, and product teams in a highly collaborative environment. Competitive Package: Receive attractive compensation and benefits aligned with your skills and performance. Key Responsibilities Model Development: Design and implement training processes for machine learning classifiers and generative models. Fine-tuning & Prompting: Adapt pre-trained models to specific product needs through fine-tuning, prompt engineering, and parameter optimization. Hyperparameter Management: Configure and tune hyperparameters to balance accuracy, robustness, and performance. Pipeline Engineering: Build scalable training and evaluation pipelines to support continuous experimentation. Integration: Collaborate with backend and product engineers to deploy models into production systems. Monitoring & Maintenance: Establish monitoring metrics and retraining strategies to maintain model performance in dynamic environments. Qualifications Bachelor’s or Master’s degree in Computer Science, Machine Learning, Data Science, or a related field.
