Job description

🌟 YOUR ROLE & RESPONSIBILITIES —

As we continue to scale and shape the future of healthcare, we are seeking an exceptional Lead Data Scientist to spearhead cutting-edge research and development efforts within our Data Science team. This is a high-impact leadership role where your work will directly influence our AI strategy, product development, and clinical value — driving innovation that can fundamentally transform how health data is understood and used.

As a Lead Data Scientist, you will:

  • Lead the design and development of state-of-the-art AI architectures tailored to longitudinal biomedical data, with a strong emphasis on laboratory test results and clinical workflows.

  • Drive the creation of reusable, pretrained models on lab data that enable transfer learning across a wide range of clinical applications (e.g., prediction, imputation, decision support).

  • Establish rigorous evaluation frameworks and benchmarks to assess model performance using clinically relevant metrics and ensure robustness and generalizability.

  • Set the scientific direction for AI initiatives, staying at the forefront of the latest advancements in machine learning and identifying emerging trends with potential applications in health.

  • Collaborate closely with cross-functional teams, including clinicians, biologists, engineers, and product stakeholders, to ensure alignment with clinical impact and real-world utility.

  • Mentor and technically guide junior and senior team members, promoting knowledge sharing, code quality, and research excellence across the team.

  • Represent the company at top-tier conferences, contributing actively to the AI and health research communities and establishing the company as a thought leader in this space.

  • Publish impactful research in major scientific venues (e.g., NeurIPS, ICML, ICLR, Nature Digital Medicine) and contribute to our scientific credibility and visibility.


Preferred experience

👤 WHO YOU ARE

We’re looking for a mission-driven, scientifically rigorous, and collaborative individual with the following qualifications:

  • PhD or Master’s in Computer Science, Machine Learning, Applied Mathematics, Engineering, or a related field.

  • At least 5 years of hands-on experience in AI/ML research, including significant time spent in leadership or strategic roles.

  • Deep expertise in modern machine learning techniques, including neural networks, representation learning, and probabilistic modeling.

  • Proven track record in developing and deploying models on real-world structured or temporal datasets; healthcare or MedTech experience is a strong plus.

  • Strong proficiency in Python (or similar languages), including standard ML libraries (e.g., PyTorch, TensorFlow, scikit-learn).

  • Demonstrated ability to lead complex projects, balance scientific rigor with product needs, and deliver results in a fast-paced environment.

  • Exceptional communication skills — able to clearly articulate complex technical concepts to both scientific and non-technical audiences.

  • Passion for mentoring and team development; you enjoy elevating others and building a culture of continuous learning and innovation.
