Job description

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 ARM‑based processors used in grid‑tied inverters and utility‑scale energy storage systems. This role requires deep expertise in ARM Cortex‑M / Cortex‑A platforms, and real‑time development, inverter control support, and grid‑code compliance. You will play a critical technical role in delivering robust, certifiable, and high‑performance firmware that integrates tightly with power electronics hardware, FPGA/DSP subsystems, and system‑level.

Responsibilities

• Architect, design, and implement embedded firmware for ARM‑based processors used in inverters, power converters, and energy storage subsystems
• Develop and maintain real‑time firmware in embedded C/C++, including task scheduling, interrupt handling, drivers, and applications
• Translate system, control, and grid‑code 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 system‑level performance and reliability
• Debug complex firmware issues, perform root‑cause 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 real‑time control systems
• Strong experience developing firmware on ARM‑based processors (e.g., Cortex‑M, Cortex‑A) for industrial or power electronics applications
• Proficiency in embedded C/C++, real‑time programming concepts, and interrupt‑driven design
• Ability to design and maintain board‑support packages (BSP), bootloaders, and device drivers
• Solid understanding of grid‑tied inverter operation, digital control concepts, and protection strategies
• Working knowledge of grid‑code behaviour such as anti‑islanding, ride‑through, and grid support functions
