• Design, implement, and support federated learning workflows that enable distributed model training and adaptation
• Develop and maintain machine learning pipelines supporting data preparation, model training, fine-tuning, evaluation, and deployment
• Analyze and preprocess data, including feature engineering and transformation, to support machine learning workflows
• Configure and optimize machine learning models and training processes to meet defined performance and operational requirements
• Evaluate model performance, behavior, and effectiveness using established metrics and validation techniques
• Develop processes and controls to ensure model adaptation and training occur within defined technical, security, and operational boundaries
• Integrate machine learning capabilities with existing applications, platforms, data sources, and infrastructure
• Troubleshoot model training, integration, performance, and distributed learning issues
• Develop reusable code, tools, and automation to support machine learning and federated learning workflows
• Collaborate with data scientists, software engineers, cloud engineers, cybersecurity teams, and other technical stakeholders to develop and integrate machine learning capabilities
• Document machine learning architectures, workflows, configurations, testing results, and technical implementation decisions
• Support version control, CI/CD, and other software engineering practices throughout the machine learning development lifecycle
• Support an Agile software development lifecycle
• Maintain awareness of emerging machine learning, model fine-tuning, federated learning, and distributed AI technologies and practices

Required:

• Ability to obtain and maintain a government security clearance
• Bachelor's degree in Computer Science, Data Science, Artificial Intelligence, Machine Learning, Engineering, Mathematics, or a related technical field, or equivalent relevant experience
• 5+ years of experience in software engineering, data science, machine learning, AI engineering, or related technical disciplines, including hands-on machine learning engineering experience
• Hands-on experience developing, training, fine-tuning, and evaluating machine learning models
• Experience designing and implementing machine learning training and inference workflows
• Experience with federated learning, distributed machine learning, or distributed model training concepts and architectures
• Strong programming experience using Python and common machine learning libraries and frameworks
• Experience with machine learning frameworks such as PyTorch, TensorFlow, scikit-learn, or equivalent technologies
• Experience with data preprocessing, feature engineering, and model evaluation techniques
• Experience developing and maintaining data and machine learning pipelines
• Knowledge of model evaluation techniques, performance metrics, and validation methodologies
