Senior Data Scientist

6-Month Contract to Hire

$90-110/hr

About the Role

We’re looking for a hands-on, highly technical Senior Data Scientist to lead the data science efforts from the ground up for our client. This role is a unique opportunity to take full ownership of their data strategy and build systems that will drive smarter decision-making across digital clinical trial recruitment , resource allocation, and protocol optimization.

You’ll be at the forefront of solving some of the hardest problems in the clinical trial ecosystem, specifically around pricing, spend optimization , and machine learning–driven trial design . You’ll operate with high autonomy, working cross-functionally across product, engineering, and operations, while owning the full data science lifecycle—from exploration to modeling to deployment.

This is a 75% individual contributor role , with potential to lead a small team (e.g., a BI analyst or data engineer). It’s ideal for someone who thrives in startup environments and is excited to bring structure, experimentation, and impact to a space ripe for innovation.

What You’ll Work On

  • Lead the development and deployment of data-driven systems that optimize trial design, pricing, and performance marketing efforts.
  • Design models to improve resource allocation and performance forecasting in a high-dimensional decision space.
  • Analyze structured and unstructured marketing and web data to optimize budget and spend across platforms like Google and Meta.
  • Apply techniques from causal inference, experimental design, and online learning (e.g., multi-armed bandits) to test and scale recruitment strategies.
  • Work directly with large, messy, real-world datasets—building pipelines, wrangling data, and making it usable.
  • Collaborate with backend engineers and product stakeholders to implement models into production systems.
  • Contribute to model development in AI/ML , with ~5–10% of your time spent on model training and experimentation.

What We’re Looking For

  • 5–10 years of experience in a data science or machine learning role; startup experience preferred.
  • Strong coding skills in Python (and/or R); deep familiarity with libraries like scikit-learn, XGBoost, PyTorch, TensorFlow .
  • Strong grasp of probability theory, statistical inference, and A/B testing .
  • Experience with causal inference and online learning methodologies.
  • Proficiency in SQL and working with real-world, imperfect data.
  • Proven ability to translate complex business problems into analytical solutions—and communicate results to both technical and non-technical stakeholders.
  • Comfortable being both strategic and hands-on : building models, cleaning data, and driving execution independently.

Nice to Have

  • Previous work in clinical trials, healthcare, or digital health
  • Experience with performance marketing analytics or web attribution modeling
  • Familiarity with trial recruitment platforms , sponsors, or CRO operations
