This job is no longer available.



The Human Factors position leads human factors (“usability engineering” in international standards) for the organization.  The person in this role contributes to product design, product development and product quality across the development lifecycle by developing and driving Dexcom’s human factors/usability strategy. Early in development, the human factors contribution may gather and clarify requirements via usability testing of prototype designs. Dexcom will design future products using a participatory design approach, and findings from testing will be fed back to design teams to improve the products. The position provides product development teams with in-depth use analysis of designs in development.


Future projects, such as those related to receiver changes, applicator improvements, phone apps, and labeling will require extensive human factors engineering activities, including but not limited to clarification of user needs, development of use cases, human factors analysis, and usability testing across the development process. The primary responsibility is to ensure that validation studies are successful; supporting rapid global regulatory approvals.


As the leader for usability evaluation, the HF Manager ensures that products are not only easy to understand and use, but also that they are safe and effective with respect to usability per FDA guidance and international standards on usability and human factors. The position is responsible for leading development and execution of formative studies and collaborating on the strategy, and then leading the development and execution of the summative testing. 


The human factors team is one of several cross-functional groups contributing to the design and optimization of Dexcom products and training materials. It is essential that this position collaborates closely with cross-functional leadership and groups.
