- Work closely with data scientists and product teams to build and deploy machine learning models, focusing on the technical aspects of model deployment.
- Implement and optimize Python-based ML pipelines for data preprocessing, model training, and deployment.
- Monitor model performance and implement strategies for bias mitigation and explainability.
- Responsible for ensuring models are scalable and efficient in production environments.
- Write and maintain code for model training and deployment, collaborating with software engineers to integrate models into applications.
- Partner with a diverse team of experts, leveraging cutting-edge technologies to build scalable and impactful AI solutions.
Minimum Qualifications – Education & Prior Job Experience:
- Bachelor’s degree in computer science, Computer Engineering, Data Science, Information Systems (CIS/MIS), Engineering or related technical discipline, or equivalent experience/training
