Preparing for this interview
Interviews for scientist roles keep coming back to Python, Machine learning, SQL, LLMs. Practise those questions before you sit with Heartflow.
Questions you are likely to be asked
- Why do you want to join Heartflow?
- What is your experience with Deep learning? Tell me one thing you learned the hard way.
- When would you not use machine learning for a problem?
- Walk me through a model you built, from the data to how it was used.
- How did you know your model was actually good, and not just good on your test set?
Prep Sarthi gives you a free mock interview: an AI interviewer asks you questions like these out loud, from your own CV and this job, and shows your score and your weakest answer.
Practise the Senior Data Scientist, Medical Imaging at Heartflow interview free →Heartflow is a medical technology company advancing the diagnosis and management of coronary artery disease, the #1 cause of death worldwide, using cutting-edge technology. The flagship product—an AI-driven, non-invasive cardiac test supported by the ACC/AHA Chest Pain Guidelines called the Heartflow FFRCT Analysis—provides a color-coded, 3D model of a patient’s coronary arteries indicating the impact blockages have on blood flow to the heart. Heartflow is the first AI-driven non-invasive integrated heart care solution across the CCTA pathway that helps clinicians identify stenoses in the coronary arteries (RoadMap™Analysis), assess coronary blood flow (FFRCT Analysis), and characterize and quantify coronary atherosclerosis (Plaque Analysis). Our pipeline of products is growing and so is our team; join us in helping to revolutionize precision heartcare.
Heartflow is a publicly traded company (HTFL) that has received international recognition for exceptional strides in healthcare innovation, is supported by medical societies around the world, cleared for use in the US, UK, Europe, Japan and Canada, and has been used for more than 750,000 patients worldwide.
We are looking for a Senior Data Scientist with a strong foundation in both statistical data analysis and deep learning to drive our data-centric AI initiatives. In this role, you will be at the forefront of understanding how diverse real-world imaging conditions and technical variables affect image appearance and, in turn, the accuracy and reproducibility of deep learning algorithms.
You will own the analytical pipeline to quantify these effects and explore data-driven methods to address them. You will work cross-functionally to translate these insights into downstream algorithm development and product decision-making, including development of annotation protocols to curate high quality annotations for training and validation. If you are drawn to deriving insight from large and messy real-world imaging data, and to communicating and crystalizing solutions from these insights, this is the role for you.
Key Responsibilities
- Tooling & Pipelines: Build robust, reproducible analytical pipelines and visualizations over population-scale data, to characterise dataset distributions and model vulnerabilities across diverse patient populations.
- Correction & Harmonization: Explore, develop, and validate methods for harmonizing complex data-related factors and image variations.
- Data-Centric Deep Learning: Translate findings about data variance and model behaviour into actionable data curation requirements, training-time robustness strategies, and architectural recommendations for downstream algorithm development.
- Data Curation and Annotation: Develop annotation protocols for algorithm training and validation for internal product development and FDA submissions.
- Cross-Functional Collaboration and Communication: Partner with Research Scientists, Machine Learning Engineers, Systems Engineers, Process Engineers, Product and Regulatory teams. Derive and present clear analyses from messy data to drive decision-making, and provide artifacts other functions consume.
Required Qualifications
- Education: Masters or PhD Degree in Data Science, Computer Science, Medical Image Analysis, Statistics, Biomedical Engineering, or a related quantitative field.
- Experience: 5+ years (or 3+ with a PhD) of industry experience in Data Science, Machine Learning, or Image Analysis.
- Measurement Science: Working command of reproducibility and agreement statistics — variance components, Gage R&R, intraclass correlation, repeatability and reproducibility coefficients, Bland-Altman — and the judgement to separate correctable bias from irreducible variance.
- Medical Imaging Expertise: Deep understanding of medical image data structures and the physical/clinical realities of imaging. Familiarity with image processing tools and building algorithms for medical imaging data.
- Data Analysis & Statistics: Expert proficiency in Python and statistical data analysis ecosystems (e.g., pandas, scipy, statsmodels, seaborn/matplotlib). Proven ability with large, complex, and messy datasets.
- Deep Learning Experience: Hands-on experience developing or fine-tuning deep learning algorithms (preferably using PyTorch) for computer vision tasks (segmentation, classification, detection) applied to medical images.
- AI-Augmented Workflow: Demonstrated proficiency using modern agentic tools and LLMs (e.g., GitHub Copilot, Gemini, Claude) as a daily force multiplier to accelerate software development, rapidly prototype data solutions, and build reproducible pipelines.
- Communication: Exceptional ability to distill complex, multi-dimensional data analyses into clear, strategic insights for cross-functional stakeholders.
Preferred Qualifications
- Published research specifically related to domain generalization, image harmonization, or out-of-distribution (OOD) detection in medical imaging.
- Experience working with large multi-vendor CT imaging datasets, with an understanding of acquisition and reconstruction protocols.
- Proven track-record in diagnosing data- and annotation-related algorithm performance gaps, and designing data-driven solutions.
- Experience with large-scale data querying and cloud storage (e.g., AWS, SQL).
- Experience developing SaMD products and contributing to regulatory filings.
- Experience with biostats to support FDA submissions.
A reasonable estimate of the base salary compensation range is $170,000 to $240,000, bonus, and equity. #LI-IB1 #LI-Hybrid
