Practice Strong Data Stewardship: Apply a deep understanding of data quality, structure, and pipelines to ensure models are trained, validated, and monitored on solid foundations. Spot anomalies, gaps, and biases before they become problems.
Ensure Rigor in Production: Champion robust data science principles in deployed systems, collaborating with software engineering teams to ensure our models are sound and reliable at scale.
Collaborate to Drive Outcomes: Partner effectively with product and business leaders to define problems and deliver AI/ML solutions that drive measurable, meaningful outcomes.
Stay on the Cutting Edge: Continuously monitor advancements in AI/ML and surface opportunities for the safe and impactful application of new technologies in both product and enterprise contexts.
Mentor and Guide: Share knowledge generously, helping teammates sharpen their technical and strategic skills while fostering a collaborative culture.
Strong expertise in Python and SQL, with fluency in machine learning frameworks and cloud-based platforms (Databricks, Snowflake, AWS, etc.).
Proven, hands-on experience building and evaluating generative AI models (LLMs, transformers, multimodal architectures) in production environments.
Demonstrated experience assessing the safety, fairness, and clinical effectiveness of AI solutions in healthcare or other high-stakes domains.
A deep understanding of data—from pipelines and transformations to intuition about patterns, anomalies, and the downstream impact of data quality.
Ability to influence executives and collaborate effectively across engineering, product, and clinical teams.
A strong foundation in statistics, econometrics, and machine learning, with a proven ability to apply theory to business-critical problems.
A track record of mentoring and elevating peers, fostering a collaborative and innovative culture.
