Responsibilities
- Own the design and development of end-to-end intelligent systems combining predictive modeling, LLMs, and domain-specific SLMs
- Design and deploy predictive models (e.g., classification, regression, ranking, time series forecasting, anomaly detection, churn and risk modeling, and recommender systems), and integrate these signals into LLM- and SLM-based systems (e.g., RAG pipelines, decision engines)
- Build and fine-tune proprietary SLMs trained on clinical notes and healthcare corpora
- Develop and deploy LLM-based and agentic AI systems for reasoning, automation, and decision support
- Engineer and optimize models across structured and unstructured data (tabular, text, and image)
- Develop advanced clinical NLP solutions using embeddings, semantic search, and domain-specific models (e.g., ClinicalBERT, PubMedBERT)
- Extract insights from large-scale unstructured healthcare data, including clinical text corpora
- Build and extend multimodal AI capabilities, including computer vision models (e.g., image classification) as complementary systems
- Prototype and explore emerging approaches in LLMs, SLMs, and agentic AI to drive continuous innovation
- Translate AI outputs into actionable clinical and business insights
- Lead end-to-end delivery, from rapid prototyping and MVP development to scalable production systems
- Partner with engineering, product, and business stakeholders to align AI solutions with strategic goals
- Deploy and monitor ML/LLM/SLM systems, including model performance, drift, bias, and impact
- Implement MLOps best practices, including CI/CD, model lifecycle management, and scalable cloud deployment (Azure/AWS)
- Drive Responsible AI practices, including explainability, governance, and compliance in healthcare environments
- Opportunity to shape the direction of applied AI systems in a rapidly evolving healthcare domain
- Exposure to cutting-edge techniques across LLMs, SLMs, and agentic AI
- Clear path to expanded ownership, technical leadership, and strategic influence
Skills
- Bachelor's degree in Data Science, Computer Science, Statistics, Engineering, Mathematics, or a related quantitative field, or equivalent practical experience
- 4+ years of experience in data science, machine learning, or applied AI, with strong foundations in statistical modeling
- Proven experience developing and deploying LLM and/or SLM-based systems in real-world environments
- Hands-on expertise fine-tuning domain-specific models (e.g., LoRA, QLoRA, RLHF, DAPT, DPO)
- Strong experience in predictive modeling, including feature engineering, validation, and production deployment
- Experience working with structured and unstructured data, particularly NLP and text-based systems domain-specific models (e.g., ClinicalBERT, PubMedBERT)
- Proficiency with modern AI/ML ecosystems, including Hugging Face, PyTorch/TensorFlow, Databricks, and MLOps practices
- Ability to independently own and drive complex AI solutions from concept to production
- Master's degree in a quantitative or technical field
- Experience working with clinical or healthcare data
- Exposure to multimodal AI systems (text + image)
- Experience developing domain-specific or proprietary language models
