Software Engineer (Firmware)

• At Harbinger, we are redefining the performance of electric vehicles. We are seeking a highly skilled Software Engineer, Firmware to design and implement the bare-metal and RTOS-based firmware that drives our advanced motor control systems.
• In this role, you will work at the intersection of hardware and software, squeezing every cycle out of the microcontroller to ensure nanosecond-level determinism, safety, and efficiency in our EV powertrains
• Firmware Architecture & Development: Design, implement, and maintain highly deterministic embedded firmware for advanced EV motor control systems operating in bare-metal and RTOS environments
• BSP & Driver Configuration: Configure and optimize vendor Board Support Packages (BSPs) and write low-level hardware drivers to ensure optimal performance of application software
• Algorithm Implementation: Deploy, tune, and optimize complex control algorithms, including high-frequency Field-Oriented Control (FOC)
• System Optimization: Relentlessly enhance CPU efficiency, reduce interrupt latency, optimize memory footprints, and ensure the system meets strict performance and safety goals
• Testing & Validation: Perform rigorous testing, debugging, and validation using real-time simulation and Hardware-in-the-Loop (HIL) environments
• Cross-Functional Integration: Work closely with hardware, application software, and power electronics teams to seamlessly integrate firmware with the broader motor control system
• Documentation: Create and maintain clean, comprehensive documentation covering firmware design, architecture, and testing methodologies
