As an Embedded Software Engineer Intern, you will join the team to contribute to the embedded software stack that runs on and around this radio - from low-level firmware and drivers up to the tooling and infrastructure used to validate it. The scope is intentionally broad: you will get exposure to the full embedded software lifecycle in the context of a custom hardware project. The duration of this internship is 5-6 months. Responsibilities - Firmware development: Actively contribute to the development of the firmware for the radio and its surrounding embedded platform, utilizing C within an Eclipse ThreadX real-time environment. - Low-Level Integration: Implement, and debug low-level drivers and communication protocols (SPI, I2C, UART) to manage interfaces between the chip and host systems. -
