Sr. Firmware Engineer

Core Responsibilities

• Design, implement, and test embedded firmware for battery-operated RF AMI and metering products.
• Collaborate with cross-functional teams (hardware, test, analytics, and system software) to ensure seamless integration and performance.
• Optimize firmware for power consumption, memory usage, and overall system efficiency in resource-constrained environments.
• Create and maintain testing frameworks, tools, and scripts (e.g., Python, C#, xUnit, Ceedling) to support validation and performance analysis.
• Support hardware design activities, including circuit design, PCB layout, and microcontroller configuration.
• Create and execute test plans and contribute to continuous integration and product validation efforts.
• Investigate field returns and partner with quality teams to identify root causes and drive product improvements.
• Contribute to technical documentation, system specifications, and firmware architecture improvements to support scalability and sustainability.

Required Qualifications

• Bachelor’s degree in electrical engineering or computer science
• 3-5 years’ experience developing embedded systems or embedded OS solutions
• Strong programming experience in C for microcontrollers in resource-constrained environments (memory, power, performance)
• Experience with version control systems (e.g., Git)
• Proven ability to test, debug, and troubleshoot at both firmware and board level using lab equipment (e.g., oscilloscopes, logic analyzers)
• Experience developing PC-based tools or scripts for testing, automation, or data analysis
• Strong collaboration and communication skills, with the ability to work effectively in a team environment
• Fluency in English (written and verbal)

Preferred Qualifications

• 5+ years of experience in embedded systems or firmware development
• Experience working with high-volume or utility metering products
• Experience optimizing firmware for low power consumption, memory usage, and performance
• Experience with MSP430 or ARM Cortex-M architectures
• Experience writing assembly language in addition to C for microcontrollers
• Experience developing system specifications, product requirements, and prototype test plans
• Familiarity with RF systems, AMI technologies, or IoT-connected devices
• Experience contributing to firmware architecture improvements and development process enhancements
