Job Summary:

The Applied Research & Technology Scouting (AR&TS) team within West is responsible for driving the future of the company by identifying and developing innovative products designed to improve patient lives.  This objective will be accomplished through a mix of internal organic research and external inorganic collaboration.  The inorganic effort will span early-stage academic research to more established technologies in the private sector.  The inorganic effort will seed the organic efforts. The scope encompasses technology fields that are adjacent to and transformational to West’s core products.

The role will work within the recently established Diagnostic Research & Detection Technology team to identify and evaluate technologies and concepts in a broadly defined Biosensor space.  The team’s output will feed the development of new products and serve new markets. The timeline for realization of the products is within a 5-year time horizon. Internal to West this team will collaborate with teams focused on drug delivery and novel therapies. External to West the team will be interfacing with researchers from academic institutions translating potential value-adding technologies, through feasibility and into reality. Projects will focus on technology validation and integration.  This will require the planning and performing of experiments, designing test equipment and prototypes, and integrating different principles of optical, mechanical, and electronic engineering.

Amongst the many research avenues of interest to West is the exploration of advanced biometric sensor technologies, and their potential integration into next generation drug delivery devices.  Suitable candidates will be expected to bring a depth of expertise, knowledge of current developments in both research and industry, and will make a significant contribution to the I&T Team and the future of West.
