• Support internal reviews and documentation for AI ethics, explainability, and model risk management as part of enterprise compliance 

Qualifications 

Education and Experience:  

• Bachelor’s or Master’s degree in Computer Science, Data Science, Statistics, AI/ML, or related fields. 
• 8+ years of experience in AI/ML, data science, or applied machine learning, with 2+ years of hands-on experience with modern AI technologies, including LLMs, NLP, and deep learning frameworks. 
• Demonstrated success deploying ML models or LLM-powered applications into production at scale. 

Technical Expertise:  

• Strong programming skills in Python and experience with AI/ML libraries (Scikit-learn, PyTorch, TensorFlow, HuggingFace). 
• Experience with cloud platforms (Azure preferred; AWS or GCP acceptable). 
• Expertise in designing and optimizing AI workflows using LangChain, Haystack, or similar orchestration frameworks. 
• Familiarity with dbt, SQL, Power BI, and enterprise data integration tools. 
• Familiarity with Replit, Cursor, Jupyter, and other AI-native dev environments. 

Leadership and Communication: 

• Proven ability to lead multidisciplinary teams, mentor junior engineers, and drive cross-functional initiatives. 
• Strong communication skills with the ability to explain complex technical topics to non-technical stakeholders. 

Compliance and Governance:  

• Strong understanding of data governance, CCPA, HIPAA, and compliance requirements. 

Additional Preferred Skills: 

• Experience working in a healthcare or regulated industry (HIPAA/CCPA knowledge a plus). 
• Background in MLOps and DevOps best practices. 
• Knowledge of automated testing, CI/CD pipelines for ML, and observability tools.
