Sr. Machine Learning Engineer — ML/AI Team

Who you are

A Place for Mom is seeking a Senior Machine Learning Engineer to design, build, and scale production-grade machine learning and Generative AI systems. This role will focus on developing advanced ML and LLM-powered applications that leverage structured and unstructured data to drive business impact.

The ideal candidate combines strong foundations in traditional machine learning with hands-on experience building and deploying Large Language Model (LLM) solutions and prompt-engineered systems in production environments.

What you will do

• Machine Learning Model Development and Maintenance:
• Study and transform data science prototypes using appropriate ML and GenAI architectures.
• Design and develop machine learning and LLM-powered systems using modern GenAI architectures (e.g., RAG, prompt engineering, embeddings, vector databases).
• Solve complex problems with multilayered data sets and optimize existing machine learning libraries and frameworks.
• Construct optimized data pipelines to feed both traditional ML models and LLM-based systems.
• Run machine learning tests and experiments and document findings and results.
• Model Maintenance and Monitoring:
• Implement and monitor model and data quality checks to ensure accuracy and consistency of our models and pipelines in production.
• Ensure system reliability, performance optimization, and responsible deployment of ML and LLM solutions in production.
• Manage the full model lifecycle, including retraining, performance monitoring, and continuous improvement.
• Collaboration and Support:
• Partner with Product, Engineering and Business stakeholders to translate requirements into scalable AI/ML and GenAI solutions, contributing to system architecture and technical design.
• Provide technical guidance and support on AI/ML initiatives, delivering clear, actionable insights to stakeholders.
• Contribute to AI engineering standards and best practices across the organization.
• Best Practices and Documentation:
• Create and maintain comprehensive documentation for ML and GenAI systems, including prompt libraries, evaluation frameworks, and architectural decisions.
• Establish and promote best practices across MLOps, LLMOps and AI system governance.
