Firmware Engineer

About This Role

Firmware engineers build the firmware behind precision solar measurement products used around the world. This P3-level role contributes across the full product lifecycle, from new product design and production release through sustaining support, developing reliable embedded firmware for solar sensing and controls products. The work spans bare-metal microcontroller development, embedded Linux, hardware bring-up, automated verification, debugging, and release readiness.

Responsibilities

• Design, implement, review, and debug bare-metal embedded firmware in C for MCU-based solar sensing and controls products
• Build Python-based test tools, automated regression workflows, and release-quality verification methods to improve firmware reliability
• Develop embedded Linux services, diagnostics, and application logic
• Own hands-on hardware bring-up and integrate sensors, ADCs, communications interfaces, memory, and other peripherals using schematics, datasheets, and lab tools
• Investigate system, production, and field failures using instrumentation, logs, controlled experiments, and structured root-cause analysis
• Support firmware release readiness through clear test evidence, release notes, risk documentation, and cross-functional review
• Partner with hardware, systems, manufacturing, quality, and support teams to resolve issues and improve product performance
• Author detailed documentation of firmware designs, debug findings, test procedures, release decisions, and sustaining actions to support continuous improvement and knowledge transfer

Requirements

• Bachelor’s degree in computer engineering, software engineering, computer science, electrical engineering, or another related STEM field
• Typically five or more years of hands-on embedded firmware experience; candidates with fewer years may be considered when they demonstrate strong technical depth and experience developing and shipping new products
• Strong bare-metal embedded C expertise, including practical debugging on resource-constrained microcontroller systems
• Experience developing and releasing production-quality firmware for new products—not solely sustaining or maintenance work
• Experience with MCU peripherals and hardware/software interfaces such as SPI, I²C, UART, CAN, Ethernet, or similar
• Ability to read schematics and datasheets and use lab tools such as oscilloscopes, logic analyzers, multimeters, and debuggers
• Hands-on experience with hardware bring-up, peripheral integration, firmware validation, or production release support
• Experience investigating system-level issues using structured debugging, test evidence, and root-cause analysis
• Experience with Python for test tools, automated verification workflows, regression testing, or embedded Linux development
