This role involves rapidly designing, implementing, evaluating, and maintaining machine learning models, algorithms, APIs, and software systems in a fast succeed/fast fail environment. You will contribute both as a hands-on engineer and as a technical leader, helping guide solutions from prototype through production while ensuring performance, scalability, reliability, and maintainability. What you'll get to do Design, develop, and implement machine learning models, algorithms, and API services that meet business needs and requirements. Develop full-stack solutions including frontend, middle-tier, and backend components using technologies such as React, Python, SQL, Delta Tables, GraphQL, and PySpark. Apply machine learning techniques to large datasets to identify trends, patterns, and actionable insights. Collaborate with cross-functional teams including software developers, data scientists, data engineers, and domain experts to prototype and productionize AI-driven solutions. Prepare, clean, and preprocess large-scale datasets to ensure high data quality and suitability for training ML models. Evaluate and optimize machine learning models for accuracy, efficiency, scalability, and bias mitigation. Identify and analyze potential biases in datasets, features, and model predictions, implementing fairness and mitigation strategies where appropriate. Manage end-to-end machine learning pipelines, from data preprocessing and feature engineering through training, deployment, monitoring, and continuous improvement. Deploy and integrate machine learning models into production environments and implement monitoring systems for usage, performance, and feedback collection. Develop and maintain ML software systems, reusable libraries, testing frameworks, and automated test suites. Participate in research and development of emerging machine learning and AI technologies. Mentor junior engineers and contribute technical leadership within the team.
