Embedded Software Engineer

Responsibilities

• Design and implement bare-metal software applications for power electronics, focusing on high-resolution PWM generation, ADC synchronization, and complex timing logic
• Develop and optimize drivers for microcontroller peripherals (SPI, CAN, Ethernet) and architect memory-efficient, multi-core processing strategies
• Collaborate with power electronics controls engineers to translate controls theory into deterministic code for Cortex-R and Cortex-M architectures
• Maintain robust software build procedures and integrate code into modern CI/CD pipelines
• Profile and optimize code across multi-core environments to ensure minimal latency in time-critical control loops
• Take embedded systems from initial prototype to mass-market production

Requirements

• BS or MS in Electrical Engineering, Computer Engineering, or Computer Science
• 2+ years of experience in firmware engineering
• Expert proficiency in Rust or C
• Experience debugging embedded systems using oscilloscopes, logic analyzers, and JTAG/SWD debuggers
• Extensive experience with ARM Cortex-M and Cortex-R architectures
• Deep understanding of high-speed ADC sampling, high-resolution PWMs, and hardware timers
• Practical experience with I2C, UART, SPI, CAN/CAN-FD, and Ethernet
• Knowledge of software build systems like Make or CMake and experience with CI/CD

Preferred Qualifications

• Familiarity with UL certification standards for energy storage systems
• Experience developing bootloaders or implementing secure boot
• Experience profiling code on real-time, multi-core targets
