We are seeking a highly skilled Senior Machine Learning Engineer to join our team in advancing the frontier of AI-driven solutions. In this role, you will play a critical part in designing, implementing, and maintaining both traditional machine learning models and cutting-edge systems built with Generative AI technology. The ideal candidate will have extensive experience in GenAI, AWS services, machine learning model development and deployment processes, and data engineering tools. You will be responsible for implementing GenAI applications, evaluating models, and ensuring their performance and governance, all while aligning solutions with our business objectives.

Key Responsibilities:

• Develop, implement, and maintain robust machine learning models using GenAI.
• Engage in prompt engineering to optimize the interaction with large language models, with other AI systems or tools.
• Utilize techniques like Retrieval-Augmented Generation (RAG) to enhance AI solutions with real-time information retrieval.
• Develop and design graph databases using tools such as NetworkX or AWS Neptune for relationship-oriented data modeling.
• Fine-tune Large Language Models (LLMs) to tailor solutions to specific business needs and improve model efficiency.
• Leverage AWS services (including S3, ECS, ECR, Lambda, SageMaker, and more) to build scalable machine learning solutions.
• Utilize data engineering skills with Glue and PySpark for efficient data preparation and processing.
• Conduct model evaluation and testing to ensure accuracy, reliability, and robustness.
• Monitor machine learning models in production, implementing strategies for ongoing performance tracking and optimization.
• Ensure the security of models and data through secure API integration, utilizing tokens and comprehensive data security principles.
• Govern models in compliance with the Machine Learning Development Lifecycle (MDLC) and Machine Learning Production Lifecycle (MPLC) processes.
• Collaborate with cross-functional teams, including data scientists, engineers, and business stakeholders, to deliver impactful machine learning solutions.
• Stay up-to-date with the latest advancements in machine learning, generative AI technologies, and methodologies.
