• Implement and debug embedded protocols including CAN, Modbus, UART, SPI, and I2C
• Partner with electrical engineers on hardware/firmware integration, board bring-up, and peripheral configuration
• Debug at the hardware level using oscilloscopes, logic analyzers, JTAG/SWD probes, and protocol analyzers
• Ensure firmware meets regulatory requirements (UL, CE, FCC) and follows functional safety and cybersecurity best practices
• Establish and enforce coding standards (MISRA-C), static analysis, code review processes, and version control discipline using Git
• Support motor drive firmware and embedded control strategies
• Mentor junior firmware engineers and lead by example on best practices
• Specify microcontrollers and supporting components for new product designs
• Provide expert-level firmware support to production and field issues

• Bare-metal and/or RTOS (FreeRTOS preferred) experience
• Hardware-level debugging with JTAG/SWD, oscilloscopes, and logic analyzers
• Experience with MISRA-C, static analysis tools, and unit testing for embedded systems
• Strong Git workflow experience
• Excellent technical writing and documentation skills
• Comfortable in a hands-on lab environment with live electrical equipment
Strongly Preferred:
• Motor drive firmware or real-time control experience
• Consumer or commercial appliance industry background
• Functional safety experience (IEC 60730, IEC 61508 or similar)
• Embedded cybersecurity exposure
• Mentorship experience without formal management
Logistics
• 100% onsite at the Ripon, WI headquarters
