As a Sr SW Test Development Engineer, you will develop and execute test scripts and validations for Dexcom's CGM (continuous glucose monitoring) transmitters and receivers, focusing on BLE (Bluetooth Low Energy) interface testing, interoperability evaluation, and system-level use cases. You'll use Python, Android Debug Bridge (ADB), Ellisys, Selenium, and Appium to create functional and stability tests, debug customer-reported issues, and analyze results to inform next-generation device improvements.… The role requires 7–12 years of industry experience with at least 2–4 years in firmware/embedded testing, strong Python scripting skills, and familiarity with embedded protocols (GPIO, UART, SPI, I2C, CAN, TCP/IP, UDP). You'll work in an Agile environment, collaborating cross-functionally and using GitHub, Jira, and Confluence to manage test artifacts and defects.
