About the Role

Heartflow is seeking a high-impact Staff Data Scientist to play a leading role in advancing the company's data needs, bridging the gap between advanced research and production-grade ML systems. You will be a key technical leader and partner to Research Scientists, driving the evolution of AI algorithms through rigorous data science methodologies, strategic data curation, and cross-functional leadership.

Responsibilities

• Engage with cross-functional teams (Product, Research, Engineering, and Process Engineering) to guide the overarching vision for data analysis, curation, and annotation to improve AI models.
• Drive the definition of algorithm and data requirements necessary to deliver on end-point objectives.
• Introduce best practices and efficient processes for large-scale annotation campaigns for continuous AI product improvements.
• Spearhead the strategic design of data campaigns needed to advance AI algorithms.
• Develop comprehensive data curation strategies for AI model improvements.
• Partner with MLOps to architect data management systems for algorithm training and performance validation.
• Establish data dashboards and monitoring reports.
• Establish frameworks and develop tools to rigorously evaluate model iteration strengths and weaknesses across patient populations.
• Design and oversee data analyses using statistical techniques to illuminate AI algorithm performance.

Requirements

• Masters or PhD Degree in Engineering, Computer Science, Statistics, Data Science or related degree.
• 7+ years (or 5+ with PhD) of proven track record in Data Science, Machine Learning, Computer Vision, or Image Analysis in industry.
• Extensive experience working on complex, real-world AI problems in medical imaging or computer vision requiring careful consideration of data needs.
• Proficient in Python, including statistical and machine learning packages (e.g. scipy, sklearn, statsmodels, seaborn) with a commitment to writing clean, reproducible and scalable code.
• Familiarity with image and 3D processing tools like VTK and ITK, and visualization tools like 3DSlicer and MITK is a plus.
• Understanding of standard statistical techniques and ability to apply appropriate statistical methods to a range of data structures; experience with medical imaging data is a plus.
• Experience working with data lakes, SQL/No SQL Databases, AWS Cloud Storage, Tableau dashboards.
• Expertise in deep learning and machine learning models in production.
• Strong experience working with medical imaging data (CT and vascular imaging) is highly preferred.
• Proficiency in Agentic AI Tools: Experience integrating generative AI and agentic tools into daily workflows to act as a force multiplier—accelerating coding, prototyping, and complex data analysis—while demonstrating the critical judgment required to rigorously evaluate AI outputs for accuracy.
• Excellent written and verbal communication skills.
• Detail-oriented but able to describe complex topics in a manner that is digestible to a broad audience.
• Ability to distill complex analyses into interpretable and actionable findings.
• Committed to the success of the team and successful completion of projects.
• Able to build trust and obtain cross-functional alignment across departments.
