At BMS, digital innovation and Information Technology are central to our vision of transforming patients’ lives through science. To accelerate our ability to serve patients around the world, we must unleash the power of technology. We are committed to being at the forefront of transforming the way medicine is made and delivered by harnessing the power of computer and data science, artificial intelligence, and other technologies to promote scientific discovery, faster decision making, and enhanced patient care.

Software Engineer at R&D BI&T plays a crucial role in optimizing trials using insights generated from curated data pipelines based on study data. This position focuses heavily on creating new data pipelines, automating, and enhancing existing ones, and developing and maintaining intuitive and visually appealing user interfaces or dashboards using Tableau and React JS.

The Software Engineer I will collaborate with cross-functional teams to gather requirements, design, and develop user-friendly solutions, and ensure a seamless user experience that enhances data analysis and decision-making processes.

A successful candidate for this role will have a background as a data analyst or software developer, excelling in Python (NumPy, Pandas, etc.), and some hands-on experience with Tableau. While knowledge and some hands-on experience with React JS are beneficial, they are not mandatory.
