About The Position

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.
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 drive technical projects spanning sustaining efforts, new product development, and research initiatives, while providing deep domain expertise in sensor substrate/electrode design and characterization.

Requirements

• You have a B.S., M.S., or Ph.D. in Physics, Chemistry, Chemical Engineering, Materials Science and Engineering, Mechanical Engineering, Electrical Engineering, or a related discipline.
• You bring a strong interdisciplinary background in electrochemistry, material science, and mechanical engineering to guide sensor electrode and substrate design, fabrication processes, and characterization methods—ideally within the medical device industry.
• You have hands-on experience working in a wet lab environment.
• You demonstrate a strong work ethic, excellent organizational skills, and attention to detail.
• You communicate scientific concepts clearly and effectively—both verbally and in writing—and excel in collaborative, cross-functional settings.
• You have experience in supplier and vendor identification, screening, and qualification
• You are proficient in statistical and data analysis tools such as JMP, Origin, Python, MATLAB, or R.

Nice To Haves

• Experience with SolidWorks, COMSOL Multiphysics, Abaqus, or Ansys is a plus.

Responsibilities

• Spearhead design enhancements for Dexcom’s current sensor electrodes and substrates used in industry‑leading CGM products, supporting continuous improvement initiatives including design specification updates, process optimizations, and qualification of new vendors.
• Serve as the substrate/electrode Subject Matter Expert (SME) for major new product development programs, driving the productization of substrate innovations and ensuring seamless integration with other CGM system components such as membranes, needles, and wearables.
• Drive proof‑of‑concept initiatives for innovative electrode designs and sensor architecture prototypes, advancing concepts from early exploration to clinical and commercial feasibility.
• Develop, implement, and execute a suite of electrochemical and mechanical test methods to characterize substrate and sensor properties and guide iterative design improvements.
• Design and execute benchtop and in‑vivo experiments to evaluate both existing and emerging CGM technologies at the component, sensor‑subassembly, and full‑product levels.
• Apply advanced statistical methods to analyze large datasets and identify the key parameters driving overall product performance.
• Collaborate with cross‑functional teams across and beyond R&D—as well as external vendors—to efficiently achieve project milestones while proactively managing technical and program interdependencies.
• Prepare and deliver presentations and documentation aligned with Design Control requirements to support sensor and substrate design activities throughout the R&D lifecycle.
• Partner with intellectual property counsel to develop and document new IP arising from development efforts.

Benefits

• 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.
