The Data Scientist is a hands‑on individual contributor supporting the analytical work of the Vice President, Data Science. You will work directly on the VP's projects, taking direction and inputs from senior team members and turning them into rigorous, well‑documented analysis, models, and deliverables that support pharmaceutical, biotech, and medical technology clients.

This role suits someone who thrives in an ambiguous, fast‑moving environment. Requirements will not always arrive fully formed; you will be comfortable working from partial direction, asking good clarifying questions, making reasonable assumptions, and moving work forward without waiting to be told every next step. You will contribute across three core areas: HCP targeting and segmentation built on real‑world and prescribing data;

patient and consumer audience analytics, including journey and adherence modeling; and ML model development supporting marketing activation and measurement.

• Build, test, and refine machine learning models and predictive analytics solutions for life sciences commercial and marketing challenges.
• Contribute across the ML pipeline — data acquisition, feature engineering, model training, and validation — with support from senior team members on production deployment.
• Work within a complex, multi-source data environment — claims, prescribing, real‑world, and consumer data — learning quickly where the right data lives and flagging gaps.
• Monitor data quality and maintain data science pipelines for client data assets, including first-party and third-party data.
• Maintain analytical quality, reproducibility, and clear documentation across your own work.

• Build and maintain HCP targeting and segmentation models using NPI‑level physician data, prescribing and treatment trends, and specialty‑level behavioral signals.
• Develop patient and consumer audience models spanning condition‑level segmentation, patient journey and line‑of‑therapy analytics, adherence prediction, and behavioral propensity scoring.

• Scale and deploy custom audiences across marketing activation platforms and publishers, working within privacy‑safe, de‑identified, and clean room environments.

• Take inputs and direction from brand and account teams and translate them into well‑scoped analyses, checking assumptions along the way.
• Collaborate with audience strategy, media and marketing activation, and account teams to support the development of client recommendations.
• Summarize findings and model results for senior team members and internal stakeholders, and contribute to client‑facing materials.

• Work collaboratively with teammates across data, engineering, and technology to bring analytical solutions into practice.
• Contribute to strong team practices by documenting your work, following shared standards, and creating reusable code and tools.
• Stay curious about emerging AI and machine learning approaches, and share ideas that could…
