The opportunity to improve health on a global scale stands before us.

Meet the team: You will join a highly technical embedded systems and hardware engineering team responsible for building reliable, secure, and ultra-low-power platforms that power next-generation connected wearable devices. The team operates across silicon, real-time embedded systems, algorithms, and connectivity stacks, translating complex system requirements into robust real-world solutions. This role plays a key part in shaping device-level behavior, performance, and power efficiency throughout the full product lifecycle.

Where you come in: • You evaluate CGM system performance using prototype firmware, mobile application features, and experimental system configurations to characterize overall system behavior and performance.

• You perform BLE communication analysis using protocol sniffers, device logs, and diagnostic tools to identify issues and characterize wireless communication performance.

• You conduct power-impact analysis using Keysight power analyzers and related instrumentation to assess feature-level and system-level energy consumption.

• You investigate system anomalies, prototype feature issues, and production firmware or application defects, driving structured root-cause analysis and corrective actions.

• You develop and maintain automated test frameworks, fixture scripts, and engineering tools across Windows, macOS, and Linux environments to improve testing efficiency and repeatability.

• You create comprehensive test plans, detailed test procedures, and technical reports while presenting findings to engineering teams and leadership stakeholders.

• You develop prototype firmware features in C/C++, participate in code reviews, and contribute to architecture discussions supporting future CGM capabilities.

• You collaborate with systems, firmware, mobile application, quality, and external partner teams to define requirements, support verification activities, and evaluate interoperability across connected devices and applications.

What makes you successful: • Strong experience in embedded systems, firmware development, system validation, or prototype evaluation.

• Proficiency in C/C++ software development with experience debugging and developing embedded firmware applications.

• Experience analyzing Bluetooth Low Energy (BLE) communications using protocol sniffers, logs, and wireless diagnostic tools.

• Strong troubleshooting and root-cause analysis skills with the ability to investigate complex system-level issues spanning firmware, applications, and communications layers.

• Experience developing automated test tools, scripts, and frameworks using modern software engineering practices.

• Hands-on experience with laboratory instrumentation, power measurement equipment, and system characterization tools.

• Experience writing test plans, verification procedures, requirements documentation, and technical presentations for diverse audiences.

• Ability to work effectively across cross-functional teams and independently drive technical investigations from problem identification through resolution.

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.

Travel Required: • 5-15%

Experience and Education Requirements: Typically requires a Bachelor’s degree in a technical discipline, and a minimum of 2-5 years related experience or Master’s degree and 0-2 years’ equivalent experience.
