Embedded Software Engineer

XTEND Tampa is seeking an Embedded Software Engineer to support the development, integration, and production of autonomous drone systems. This role focuses on hands-on embedded software and firmware development for tactical UAS platforms, including low-level driver development, hardware/software integration, communication interfaces, and embedded system debugging. The engineer will work closely with electrical, mechanical, software, and production teams to ensure reliable, manufacturable, and field-ready drone systems. Main Responsibilities Embedded Software & Firmware Development Develop, maintain, and improve embedded software and firmware for autonomous drone systems using C, with occasional support using C++ and Python. Hardware / Software Integration Work directly with hardware components, embedded processors, co-processors, sensors, payload interfaces, and peripheral devices to ensure reliable system-level integration. Low-Level Driver Development Develop and support low-level drivers and communication interfaces, including I2C, UART, SPI, GPIO, and other embedded hardware protocols. Microcontroller Development Support embedded development on STM ARM microcontroller-based platforms, including firmware implementation, debugging, and hardware bring-up. System Integration Support Collaborate with electrical, mechanical, software, and production teams during prototype development, system integration, and production troubleshooting. Debugging & Troubleshooting Troubleshoot firmware, hardware, PCB, and interface-level issues using engineering tools such as oscilloscopes, logic analyzers, debuggers, and schematics. Core Operating System Support Contribute to the development and refinement of XTEND’s embedded software architecture and core operating environment for drone and payload systems. Testing & Validation Support bench testing, hardware-in-the-loop testing, system integration testing, and field validation of embedded systems. Documentation Develop and maintain embedded software documentation, interface descriptions, test procedures, troubleshooting guides, and integration notes.
