Senior ARM Firmware Engineer

About the Role:

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
