About the Role

Are you passionate about leveraging advanced analytics to drive organizational transformation? In today's data-driven landscape, we're seeking a Senior Data Scientist who can both architect sophisticated machine learning solutions and provide strategic leadership in the implementation of cutting-edge AI technologies.

As a Senior Data Scientist, you'll shape how organizations like the FDA approach their most critical challenges through data science. Working closely with executive stakeholders, you'll translate complex business problems into innovative technical solutions, mentor team members, and serve as a technical authority in machine learning and artificial intelligence.

Your role combines technical expertise with strategic vision – you'll design advanced analytical models, establish best practices, and communicate insights to diverse audiences. You'll have the opportunity to make a significant impact at the intersection of public health and regulatory science, working with forward-thinking organizations to solve challenging problems through innovative data science solutions.

About You

You are inquisitive by nature, detail oriented, creative, patient, and a results-focused problem solver who enjoys collaboration with your team. You use critical reasoning, are open-minded and enjoy the steps involved when confronted with a complex challenge. You have a high standard of accountability and can influence others by creating effective presentations that communicate complex analytics to non-technical senior management and executives.
