Data Scientist

About Role:

• We’re looking for a data scientist who is passionate about Natural Language Processing (NLP), Generative AI, and traditional machine learning—and who knows how to ship high-impact, production-grade models.
• This is a hands-on role where you’ll work across the full ML lifecycle: from prototyping to deployment, with a strong emphasis on production-readiness, APIs, and scalable architecture.
• You’ll collaborate with AI engineers, product managers, and domain experts to develop intelligent systems that power next-generation insights for the pharma industry.

Responsibilities:

• Design and develop NLP and generative AI solutions using LLM frameworks like LangChain, LlamaIndex, CrewAI, or direct model provider SDKs/APIs (e.g., OpenAI, Anthropic, HuggingFace).
• Build and fine-tune traditional ML models (e.g., classification, regression, clustering) to support data-driven applications.
• Create robust and scalable AI pipelines and APIs using Python and FastAPI.
• Deploy models to production using AWS services such as ECS, Lambda, and S3, with attention to CI/CD, observability, and cost-effectiveness.
• Apply strong system design principles to architect scalable, maintainable, and secure ML systems.
• Use critical thinking to analyze complex problems, identify edge cases, and propose pragmatic, data-driven solutions.
• Think creatively and outside the box to explore new ML techniques, tools, or approaches that push the boundaries of what we can do.
• Work closely with cross-functional teams to turn ambiguous business problems into well-scoped, technically sound AI solutions.
• Contribute to a culture of technical excellence and innovation in a fast-moving AI/ML team.

Required Experience

• Experience in data science or machine learning.
• Experience in NLP, LLMs, and generative AI—comfortable with both the theory and tooling.
• Experience with modern LLM stacks such as LangChain, LlamaIndex, CrewAI, or similar.
• Skilled in traditional ML methods using libraries like scikit-learn, XGBoost, etc.
• Python programmer —you write clean, maintainable, testable code.
• Experience exposing models as production-ready APIs using FastAPI (or similar frameworks).
• Strong understanding of AWS services—especially ECS, Lambda, and S3.
• Experience with MLOps and DevOps best practices is a plus (e.g., Docker, Terraform, Azure DevOps, Github Actions).
• Proven ability in system architecture, problem-solving, and independently leading projects from concept to deployment.
