Intern | Nantbeam AP

About the role

We are seeking a motivated Software Engineering Intern to support the development of our embedded product portfolio, including LoRa, Wi-Fi, UWB, 5G, and BLE devices such as trackers, LoRa badges, SigFox buttons, and mesh devices. This internship focuses on achieving best-in-class battery life through intelligent power management, ensuring high performance and reliability in real-world applications.

Key outcomes

• Reduce power consumption while maintaining device performance
• Enhance robustness across diverse operating scenarios
• Deliver production-quality validation and documentation for scalable deployment

Responsibilities

• Define and implement system-level and component-level power strategies (sleep states, wake sources, duty cycling) to minimize current draw without sacrificing performance
• Develop embedded firmware modules supporting LoRa, Wi-Fi, UWB, 5G, and BLE, including drivers, state machines, and multi-radio coordination logic
• Design and execute tests for corner cases and real-world conditions, including stress testing and long-duration validation
• Analyze datasheets and reference designs to configure modes, power states, and RF settings accurately
• Collaborate with chip vendors to clarify behaviors, request application notes, and resolve issues
• Support debugging in the lab using oscilloscopes, logic analyzers, and DMMs, addressing hardware and signal integrity issues
• Implement and validate low-power modes across MCUs and radios
• Measure and optimize current consumption in various operating modes
• Develop validation procedures and stress tests to prevent field failures
• Troubleshoot firmware/hardware interactions methodically
• Document findings and communicate effectively with teams and vendors

Requirements

• Coursework or experience in embedded systems and low-level programming
• Proficiency in C/C++ and familiarity with interfaces like I2C, SPI, UART, GPIO, ADC, DMA
• Ability to interpret datasheets and implement register configurations
• Hands-on experience with lab tools (oscilloscope, logic analyzer, DMM)
• Strong attention to detail and testing mindset

Preferred qualifications

• Experience with STM32, FreeRTOS, and power profiling/optimization
• Familiarity with wireless stacks (LoRaWAN, BLE, Wi-Fi) and RF integration
• Experience building test utilities, automation scripts, or CI regression testing
• Ability to review hardware schematics and troubleshoot board-level issues

Competencies

• Systems Thinking: Optimizes across MCU, radios, sensors, and power components
• Methodical Debugging: Isolates issues with a root-cause approach and validates solutions
• Quality Ownership: Anticipates scenarios and proactively enhances product robustness
• Communication: Provides clear updates, documentation, and vendor interactions
