Data Science

Position Description :

We are seeking a highly experienced and innovative Senior AI Engineer to join our rapidly expanding AI / ML team. With 7+ years of hands-on experience, you will be instrumental in the end-to-end lifecycle of AI / ML solutions - from research and prototyping to developing, deploying, and maintaining production-grade intelligent systems. You will work on challenging problems, collaborate closely with data scientists, product managers, and software engineers, and drive the adoption of cutting-edge AI technologies across our platforms.

Your future duties and responsibilities :

• Model Development & Implementation : Design, develop, train, and optimize robust and scalable machine learning models (e.g., deep learning, classical ML algorithms) for various applications.
• Production Deployment (MLOps) : Build and maintain end-to-end MLOps pipelines for model deployment, monitoring, versioning, and retraining, ensuring reliability and performance in production environments.
• Data Engineering for AI : Work with large, complex datasets, performing data cleaning, feature engineering, and data pipeline development to prepare data for model training and inference.
• Research & Prototyping : Explore and evaluate new AI / ML technologies, algorithms, and research papers to identify opportunities for innovation and competitive advantage. Rapidly prototype and test new ideas.
• Performance Optimization : Optimize AI / ML models and inference systems for speed, efficiency, and resource utilization.
• Collaboration & Communication : Partner closely with Data Scientists to transition research prototypes into production-ready solutions. Collaborate with Software Engineers to integrate AI models into existing products and platforms. Communicate complex AI concepts to both technical and non-technical stakeholders.
• Code Quality & Best Practices : Write clean, maintainable, and well-documented code. Advocate for and implement software engineering best practices within the AI / ML lifecycle.
• Monitoring & Maintenance : Implement robust monitoring for model performance, data drift, and system health in production, and troubleshoot issues as they arise.
