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.

Dexcom, Inc. empowers people to take control of diabetes through innovative continuous glucose monitoring (CGM) systems. Headquartered in San Diego, California, Dexcom has emerged as a leader in diabetes care technology. By listening to the needs of users, caregivers, and providers, Dexcom simplifies and improves diabetes management around the world. We are seeking a highly skilled and motivated Staff Test Engineer to join our team.

The primary focus of this position is to define, lead, and execute design verification strategies for sensor‑based CGM systems, with emphasis on sensor performance, robustness, environmental sensitivity, and use‑condition simulation. This role serves as a technical leader for sensor‑focused verification activities across development, design changes, and lifecycle support.

• Serve as a technical interface between Sensor Engineering, Systems Engineering, and Quality, translating sensor performance intent into executable and defensible verification strategies.
• Own sensor‑focused design verification strategy, including test coverage, rationale, and risk alignment for sensor performance requirements.
• Design and implement cost‑effective test methods for electro‑mechanical systems.
• Create and maintain verification documentation, including test plans, protocols, and reports.
• Apply statistical analysis to drive engineering conclusions, risk decisions, and verification sufficiency, and clearly communicate rationale to cross‑functional stakeholders.
• Demonstrated expertise in defining and applying accelerated aging and shelf‑life verification strategies, including Arrhenius‑based Q10 methodology, to support design verification decisions and product lifecycle claims in accordance with industry standards (e.g., ASTM F1980)
• Develop and implement sensor‑specific test methods to evaluate accuracy, stability, drift, environmental sensitivity, and robustness under simulated use and misuse conditions.
• Assess and lead verification impact for sensor design, material, process, or supplier changes, including definition of appropriate verification scope and justification.
• Design, fabricate, and troubleshoot test fixtures and equipment.

• You demonstrate strong engineering judgment in balancing test rigor, risk, timelines, and regulatory expectations.
• Strong analytical and problem‑solving skills.
• You effectively influence technical direction across functions without direct authority and clearly present complex technical data to drive alignment and decision‑making.
• Provide clear, traceable technical rationale in verification documentation to support regulatory review and audits.
• Demonstrated capability to lead and positively influence technical decisions considering both short‑term and long‑term impacts.

• A front row seat to life changing CGM technology. Learn about our…
