Position Title: Senior ARM Firmware Engineer
Department: Inverter Firmware
Compensation: $100,000 - $150,000 + annual bonus
Reports To: Director of Digital Inverter Firmware
Location: Kitchener, Ontario - Hybrid

About the Role:

The Senior Embedded Firmware Engineer owns the design, development, optimization, and lifecycle support of embedded firmware running on ARMbased processors used in gridtied inverters and utilityscale energy storage systems. This role requires deep expertise in ARM CortexM / CortexA platforms, and realtime development, inverter control support, and gridcode compliance. You will play a critical technical role in delivering robust, certifiable, and highperformance firmware that integrates tightly with power electronics hardware, FPGA/DSP subsystems, and systemlevel

Responsibilities:

• Architect, design, and implement embedded firmware for ARMbased processors used in inverters, power converters, and energy storage subsystems

• Develop and maintain realtime firmware in embedded C/C++, including task scheduling, interrupt handling, drivers, and applications

• Translate system, control, and gridcode requirements into traceable firmware requirements and robust designs

• Implement inverter features such as communication, protections, fault handling, diagnostics, and monitoring

• Support compliance with grid and firmware standards (UL 1741 SB, IEEE 1547, UL 1998) and certification testing activities

• Collaborate with hardware, controls, systems, and validation teams to ensure systemlevel performance and reliability

• Debug complex firmware issues, perform rootcause analysis, and optimize performance using lab tools and emulators

• Participate in firmware architecture reviews, code reviews, and technical risk assessments

• Maintain clear firmware documentation and contribute to process improvement and release quality

Required Qualifications and Skills:

• Educational background in Electrical Engineering, Computer Engineering, Computer Science or a related field

• At least 5 years' of experience in professional firmware development experience in embedded or realtime control systems

• Strong experience developing firmware on ARMbased processors (e.g., CortexM, CortexA) for industrial or power electronics applications

• Proficiency in embedded C/C++, realtime programming concepts, and interruptdriven design

• Ability to design and maintain boardsupport packages (BSP), bootloaders, and device drivers

• Solid understanding of gridtied inverter operation, digital control concepts, and protection strategies

• Working knowledge of gridcode behaviour such as antiislanding, ridethrough, and grid support functions
