Position Summary: Describe below the primary purpose and function of this job
We are looking for a Machine Learning Engineer with expertise in traditional Artificial Intelligence (AI) techniques, such as statistical modeling, classical machine learning algorithms, and optimization methods. The ideal candidate will have a strong foundation in implementing, deploying, and fine-tuning traditional AI solutions to solve real-world problems, while also being familiar with modern tools and techniques for AI/ML workflows. This role focuses on leveraging tried-and-true AI methods to build efficient and interpretable models, process data, and improve decision-making systems across various business domains.
Key Duties & Responsibilities: List up to 5 key duties and responsibilities, management responsibilities and time spent (if applicable)
1. AI/ML Model Development: - Design, implement, and optimize traditional AI algorithms such as regression models, decision trees, random forests, support vector machines (SVM), clustering (e.g., K-means), and ensemble methods. - Leverage techniques like dimensionality reduction (e.g., PCA, LDA), and optimization algorithms to improve model performance. 2. Data Processing and Feature Engineering: - Work on pre-processing structured and unstructured datasets using techniques like data cleaning, normalization, and feature extraction. - Identify and engineer relevant features for classical machine learning models. 3. Model Deployment & Monitoring: - Deploy models into production systems and ensure their scalability and reliability. - Monitor and maintain deployed models to ensure long-term performance. 4. Evaluation and Validation: - Use statistical and validation methods (e.g., cross-validation, A/B testing) to evaluate model accuracy and generalization. - Interpret results and provide actionable insights. 5. Collaboration and Documentation: - Collaborate with data scientists, software engineers, and product teams to integrate AI models into applications. - Document model design, implementation details, and performance results comprehensively. 6. Optimization & Efficiency: - Focus on designing lightweight, explainable models that prioritize computational efficiency.
