The Company

Dexcom Corporation (NASDAQ DXCM) is a pioneer and global leader in continuous glucose monitoring (CGM). Dexcom began as a small company with a big dream: To forever change how diabetes is managed. To unlock information and insights that drive better health outcomes. Here we are 25 years later, having pioneered an industry. And we're just getting started. We are broadening our vision beyond diabetes to empower people to take control of health. That means personalized, actionable insights aimed at solving important health challenges. To continue what we've started: Improving human health.

 

We are driven by thousands of ambitious, passionate people worldwide who are willing to fight like warriors to earn the trust of our customers by listening, serving with integrity, thinking big, and being dependable. We've already changed millions of lives and we're ready to change millions more. Our future ambition is to become a leading consumer health technology company while continuing to develop solutions for serious health conditions. We'll get there by constantly reinventing unique biosensing-technology experiences. Though we've come a long way from our small company days, our dreams are bigger than ever. The opportunity to improve health on a global scale stands before us.

Meet the team:

The Sensor Design and Characterization group within the Research and Development (R&D) organization is dedicated to the design and development of cutting-edge sensor technologies, guiding them from initial concept through to commercialization. These innovations are essential to improving the accuracy, reliability, and robustness of CGM systems. Our multidisciplinary team brings together individuals from diverse backgrounds and experience levels, fostering a collaborative and dynamic environment that drives creative problem-solving and breakthrough solutions.

In this role, you will lead technical projects spanning sustaining efforts, new product development, and research initiatives, while providing deep domain expertise in sensor substrate/electrode design and characterization.

Where you come in:

  • You will spearhead design enhancements and investigations for Dexcom’s current sensor electrodes and substrates used in industry-leading CGM products, supporting continuous improvement initiatives such as design specification updates, process improvements, and qualification of new vendors.

  • You will serve as the substrate/electrode Subject Matter Expert (SME) in major new product development programs, driving the productization of substrate innovations and integration with other CGM system components, including membranes, needles, and wearables.

  • You will lead proof-of-concept initiatives for novel electrode designs and sensor architecture prototyping, advancing concepts from early-stage development through clinical and commercial feasibility.

  • You will devise and implement a comprehensive suite of mechanical test methods to characterize substrate properties and inform iterative design improvements.

  • You will apply advanced statistical methods to analyze large datasets, evaluate component performance, and identify key parameters that drive product performance.

  • You will collaborate with cross-functional teams within and beyond R&D, as well as external vendors, to efficiently achieve project milestones while proactively managing interdependencies.

  • You will deliver presentations and documentation in compliance with Design Control processes to support sensor and substrate design activities throughout the R&D lifecycle.

  • You will partner with intellectual property counsel to develop and provide documentation for new IP resulting from development efforts.

What makes you successful:

  • You have a B.S., M.S., or Ph.D. in Materials Science and Engineering, Mechanical Engineering, Metallurgy, or a related discipline.

  • You bring deep expertise in material science and mechanical engineering to influence sensor electrode and substrate design, processes, and characterization methods, with significant experience in the medical device industry.

  • You are adept at managing complex projects, navigating uncertainties and risks, and meeting deadlines in a fast-paced R&D environment.

  • You have exceptional scientific communication skills—both verbal and written—and thrive in collaborative environments.

  • You have proven experience in supplier and vendor identification, screening, and qualification

  • You possess a strong work ethic and excellent interpersonal skills.

  • You are knowledgeable and experienced in medical device regulations, such as ISO 13485, FDA 21 CFR § 820.30 Design Controls.

  • You are proficient in statistical and data analysis tools such as JMP, Origin, Python, MATLAB, or R.

What you’ll get:

  • A front row seat to life changing CGM technology. Learn about our brave #dexcomwarriors community.

  • A full and comprehensive benefits program.

  • Growth opportunities on a global scale.

  • Access to career development through in-house learning programs and/or qualified tuition reimbursement.

  • An exciting and innovative, industry-leading organization committed to our employees, customers, and the communities we serve.

Education and Experience:

  • Typically requires a Bachelor’s degree in a technical discipline, and a minimum of 8-12 years related experience or Master’s degree and 5-7 years equivalent industry experience or a PhD and 2-4 years of experience.
