About The Position

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: 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 design, develop, test, and debug high‑quality embedded system software for ultra‑low‑power devices, with a strong focus on performance, security, reliability, and energy efficiency. You lead rapid prototyping and proof‑of‑concept efforts to evaluate new ideas, technologies, and architectures, iterating quickly to refine solutions. You work closely with hardware engineering teams to understand device capabilities and constraints, optimizing software behavior for specific hardware configurations. You contribute across the full system development lifecycle, including requirements analysis, design tradeoffs, implementation, verification, and system integration. You develop low-level software in C/C++ for ARM-based or similar microcontrollers, operating on bare-metal or using lightweight RTOS such as Zephyr or FreeRTOS. You work closely with algorithm and systems engineers to integrate and optimize device-level algorithms. You design, implement, and debug BLE communication using vendor-provided stacks. You troubleshoot complex technical issues and drive effective solutions independently or in collaboration with cross‑functional teams
