Data Scientist

Role SummaryWe are seeking a highly hands-on Data Scientist with 4+ years of experience who is deeply proficient in **Large Language Models (LLMs)**both open-source and commercial—and has strong expertise in prompt engineering, applied machine learning, and local LLM deployments.This role is not purely academic. The ideal candidate will work on real-world AI systems, including AI Frontdesk, AI Clinician, AI RCM, multimodal agents, and healthcare-specific automation, with a focus on production-grade AI, domain-aligned reasoning, and privacy-aware architectures.Key Responsibilities1. LLM Research, Evaluation & Selection

• Evaluate, benchmark, and compare open-source LLMs (LLaMA-2/3, Mistral, Mixtral, Falcon, Qwen, Phi, etc.) and commercial LLMs (OpenAI, Anthropic, Google, Azure).
• Select appropriate models based on latency, accuracy, cost, explainability, and data-privacy requirements.
• Maintain an internal LLM capability matrix mapped to specific business use cases.

2. Prompt Engineering & Reasoning Design

• Design, test, and optimize prompt strategies:

• Zero-shot, few-shot, chain-of-thought (where applicable)

• Tool-calling and function-calling prompts

• Multi-agent and planner-executor patterns

• Build domain-aware prompts for healthcare workflows (clinical notes, scheduling, RCM, patient communication).

• Implement prompt versioning, prompt A/B testing, and regression checks.

3. Applied ML & Model Development

• Build and fine-tune ML/DL models (classification, NER, summarization, clustering, recommendation).
• Apply traditional ML + LLM hybrids where LLMs alone are not optimal.
• Perform feature engineering, model evaluation, and error analysis.
• Work with structured (SQL/FHIR) and unstructured (text, audio) data.

4. Local LLM & On-Prem Deployment

• Deploy and optimize local LLMs using frameworks such as:

• Ollama, vLLM, llama.cpp, HuggingFace Transformers

• Implement quantization (4-bit/8-bit) and performance tuning.

• Support air-gapped / HIPAA-compliant inference environments.

• Integrate local models with microservices and APIs.

5. RAG & Knowledge Systems

• Design and implement Retrieval-Augmented Generation (RAG) pipelines.
• Work with vector databases (FAISS, Chroma, Weaviate, Pinecone).
• Optimize chunking, embedding strategies, and relevance scoring.
• Ensure traceability and citation of retrieved sources.

6. AI System Integration & Productionization

• Collaborate with backend and frontend teams to integrate AI models into:

• Spring Boot / FastAPI services

• React-based applications

• Implement monitoring for accuracy drift, latency, hallucinations, and cost.

• Document AI behaviors clearly for BA, QA, and compliance teams.

7. Responsible AI & Compliance Awareness

• Apply PHI-safe design principles (prompt redaction, data minimization).
• Understand healthcare AI constraints (HIPAA, auditability, explainability).
• Support human-in-the-loop and fallback mechanisms.

8. AI Strategy & Roadmap

• Design and implement AI strategies aligned with business objectives, product vision, and healthcare use cases.
• Identify opportunities to leverage LLMs, Generative AI, agentic AI, and traditional ML to improve operational efficiency, automation, and customer experience.
• Define AI roadmaps, priorities, architecture, and implementation plans from proof-of-concept through production.
• Evaluate emerging AI technologies and recommend solutions based on business value, scalability, cost, security, and compliance.

Required Skills & QualificationsCore Technical Skills

• Strong proficiency in Python (NumPy, Pandas, Scikit-learn).
• Solid understanding of ML fundamentals (supervised/unsupervised learning).
• Hands-on experience with LLMs (open-source + commercial).
• Strong command of prompt engineering techniques.
• Experience deploying models locally or in controlled environments.

LLM & AI Tooling

• HuggingFace ecosystem
• OpenAI / Anthropic APIs
• Vector databases
• LangChain / LlamaIndex (or equivalent orchestration frameworks)

Data & Systems

• SQL and data modeling
• REST APIs
• Git, Docker (basic)
• Linux environments

Preferred / Good-to-Have Skills

• Experience in healthcare data (EHR, clinical text, FHIR concepts).
• Exposure to multimodal AI (speech-to-text, text-to-speech).
• Knowledge of model evaluation frameworks for LLMs.
• Familiarity with agentic AI architectures.
• Experience working in startup or fast-moving product teams.

Research & Mindset Expectations (Important)

• Strong inclination toward applied research, not just model usage.
• Ability to read and translate research papers into working prototypes.
• Curious, experimental, and iterative mindset.
• Clear understanding that accuracy, safety, and explainability matter more than flashy demos.

What We Offer

• Opportunity to work on real production AI systems used in US healthcare.
• Exposure to end-to-end AI lifecycle: research prototype production.
• Work with local LLMs, agentic systems, and multimodal AI.
• High ownership, visibility, and learning curve.

• Friendly Environment
• Excellent Salary
• 5 Days Working
• Medical + Accidental Insurance
• On-site Yoga, Gym, Sports, and Bhagwat Geeta Session
• Excellent Work-life balance
• Annual one-day Trip
• All festival celebrations
