Senior Data Scientist

Roles & Responsibilities

Analytical Delivery & Modeling

• Design, develop, and deploy predictive modeling and data science solutions — including regression,clustering, survival analysis, time series forecasting, and Monte Carlo simulation — to address clinical development challenges.
• Conduct rigorous statistical investigations and exploratory data analysis across clinical datasets including trial data, EHR/EMR, and real-world evidence (RWE).
• Translate moderately ambiguous scientific or operational problems into structured, hypothesis-driven analytical frameworks spanning study feasibility, trial execution, and patient analytics.
• Build and maintain data and analytics pipelines — contributing to pipeline design decisions and ensuring computational efficiency within established architectural patterns.
• Partner with senior data scientists and engineering teams on data quality, pipeline reliability, and scalability improvements.

AI & GenAI Solutions

• Design and implement AI/GenAI-powered solutions — including LLMs, RAG frameworks, and Agentic AI architectures — to augment clinical workflows and decision-making under senior guidance.
• Apply prompt engineering best practices and contribute to LLM orchestration patterns within the clinical development context.
• Stay current with emerging AI/ML methodologies and proactively surface opportunities to apply new techniques to clinical problems.

• Stakeholder Engagement & Communication
• Collaborate with clinical, medical, and scientific stakeholders to define project objectives, shape data-driven hypotheses, and align on KPIs.
• Present analytical findings and recommendations to functional leads and cross-functional teams through clear visualizations and structured narratives.
• Communicate trade-offs between analytical approaches clearly and confidently, with appropriate scientific justification.Engineering & MLOps Practices
• Apply MLOps and GitOps practices in your own work — ensuring models and pipelines are versioned,documented, and maintainable.
• Adhere to and actively contribute to engineering standards, code quality, and best practices established by the team.
• Work within cloud platforms (AWS/Azure), big data technologies (Spark), and version control tooling(GitHub) at scale.
• Support junior data scientists with technical guidance and peer code review as needed.

Skills & Competencies

Technical Skills

• Strong proficiency in Python, PySpark, or R — including clinical and statistical packages and ML frameworks.
• Solid understanding of experimental design, hypothesis testing, survival analysis, and clinical trial statistical methodologies.
• Hands-on experience with modern data pipeline and orchestration frameworks (e.g., Kedro, Dagster,Airflow).
• Practical working knowledge of AI/GenAI technologies — LLMs, RAG frameworks, Agentic AI, and prompt engineering.
• Experience with agentic AI frameworks such as LangChain, AutoGen, LlamaIndex, or OpenAI Agents in project or near-production settings.
• Familiarity with SDLC principles; exposure to front-end development (e.g., React) is a plus.
• Understanding of clinical trial data structures and standards
• Familiarity with real-world data (RWD) sources including claims, EHR/EMR, an patient registries.

Soft Skills

• Clear and structured communication — able to present complex findings to both technical peers and clinical stakeholders.
• Strong analytical and problem-solving skills with the ability to navigate ambiguity independently.
• Collaborative mindset with a drive for scientific rigor and continuous learning.
• Ability to evaluate and articulate trade-offs between different methodologies with sound judgment.

Experience

• Bachelor's, Master's, or Ph.D. in Data Science, Statistics, Biostatistics, Computer Science, or a related discipline.
• 5+ years of progressive experience in data science or ML engineering, with meaningful exposure to biopharma, pharma, or clinical research settings.
• Demonstrated track record of delivering end-to-end analytical or ML solutions — from problem framing through deployment.
• Experience working with clinical trial data, EHR/EMR, or RWE/RWD sources; Understanding of data governance in regulated environments.
• Working knowledge of the biopharma drug development lifecycle — clinical phases, regulatory landscape, and data standards.
• Practical experience with AI/GenAI technologies — LLMs, RAG, Agentic AI, and prompt engineering —applied to real or near-real use cases.
• Familiarity with model explainability (XAI) and HIPAA compliance considerations in clinical data workflows.
• Experience contributing to capability assessments or tool evaluations is a plus.

Good to Have

• Hands-on experience with LLM-driven or LLM-augmented workflows in a clinical or drug development context.
• Experience building and deploying data science applications with a React-based front end and Python/API-driven back end.
• Familiarity with responsible AI principles — fairness, transparency, and explainability in clinical settings.
• Contributions to open-source AI/GenAI projects, publications, or participation in relevant hackathons or conferences.
• Exposure to AI/ML capability roadmap initiatives or center-of-excellence (CoE) contributions.
