Firmware Engineer at No Limit Technology

Job Title: Embedded Firmware Engineer Drones & IoTJob SummaryWe are seeking a highly skilled Embedded Firmware Engineer with strong experience in drone systems microcontrollers and IoT hardware. The ideal candidate will develop optimize and maintain firmware that powers flight-critical and sensor-driven platforms. This role involves working closely with hardware software and product teams to build robust high-performance embedded solutions.Key Responsibilities Develop and debug embedded firmware in C/C for drone microcontrollers typically on resource-constrained platforms. Design and implement device drivers for sensors (IMU GPS cameras) communication interfaces (UART SPI I2C CAN) and actuator systems. Perform board bring-up and hardware validation including working on new/revised PCBs schematic reviews flashing and functional testing. Optimize firmware for performance power efficiency and memory usage on low-resource microcontrollers. Integrate firmware with flight control stacks such as PX4 or ArduPilot as well as higher-level application logic. Identify diagnose and resolve hardwaresoftware interaction issues involving sensors communication modules power systems and real-time control loops. Conduct bench and flight testing to validate firmware behavior ensure safety and fine-tune flight performance. Document firmware design architecture and usage creating maintainable technical guides for internal teams and future development. Collaborate with cross-functional teams across hardware electronics mechanical and software engineering to co-design systems and support new product features. Build firmware for IoT microcontrollers (ESP32 Arduino-class boards) including assembly interfacing and sensor/communication integration.Desired Skills & Qualifications Strong experience developing firmware in C/C for microcontrollers (STM32 ARM Cortex series etc.) on bare-metal or RTOS environments. Deep understanding of embedded systems fundamentals: interrupts timers real-time scheduling memory management and low-level communication protocols. Hands-on experience with debugging tools such as oscilloscopes JTAG/SWD logic analyzers and serial debuggers. Proficient with Git agile development workflows and automated unit or regression testing methodologies. Experience with drone control frameworks (PX4 ArduPilot) is a strong advantage. Ability to create clear technical documentation and communicate complex concepts effectively. Understanding of system safety standards compliance requirements and practical flight-testing methodologies. Familiarity with IoT hardware platforms (ESP32 Arduino) and the ability to assemble test and write firmware for connected devices.
