Sr SW Development Engineer; Mobile Apps

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.

• 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.

• Experienced in software development, with a strong focus on embedded systems and firmware.
• Expertise in programming languages such as C, C++.
• Strong understanding of real‑time operating systems (RTOS) and embedded systems architectures.
• Proven experience in developing and debugging complex embedded firmware.
• Experience with various communication protocols (e.g., Bluetooth, Wi‑Fi, BLE, TCP/IP, serial interfaces).
• Experience with tools like JIRA, use of AI tools for code generation and testing.

• 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.

• 5‑15%

Typically requires a Bachelor’s degree in a technical discipline, and a minimum of 5‑8 years related experience or Master’s degree and 2‑5 years equivalent industry experience or a PhD and 0‑2 years experience.

Your primary location will be a home office. You will not have an assigned workstation and will work with your manager to determine office visit needs. You must live within commuting distance of your assigned Dexcom site (typically 75 miles/120km).
