Embedded Firmware Test Engineer

We are seeking an Embedded Firmware Test Engineer to join our growing engineering team developing next-generation power electronics and energy storage products. You'll become part of a collaborative team of experienced and junior engineers supporting multiple active development programs. This role is ideal for an engineer who enjoys working at the intersection of embedded firmware, hardware validation, and data analytics.

You'll leverage established test plans and procedures to validate embedded systems, automate testing using Python, and analyze test results to ensure products meet performance, reliability, and regulatory requirements.

Responsibilities - Execute firmware and hardware validation testing for embedded power electronics and inverter systems using established test plans and procedures. - Perform board-level validation of embedded systems and microcontroller-based hardware. - Validate products against industry standards and certification requirements, including ISO 17025 laboratory processes. - Conduct hands-on testing in a fully equipped onsite laboratory environment. - Collect, analyze, and interpret large volumes of test data to identify trends, anomalies, and product performance issues. - Develop clear, detailed validation reports and maintain comprehensive engineering documentation. - Develop and maintain Python scripts to automate test execution, data collection, analysis, and reporting. - Debug firmware and hardware issues using Python and standard laboratory instrumentation. - Support component-level testing, including electrical fault and short-circuit evaluations. - Collaborate with firmware, hardware, and systems engineering teams to investigate failures and drive root cause analysis. - Continuously improve automated test frameworks, validation processes, and laboratory efficiency.

Required

Qualifications - Bachelor's degree in Electrical Engineering, Computer Engineering, Embedded Systems, or a related engineering discipline. - 4+ years of experience testing embedded firmware systems and microcontroller-based products. - Strong understanding of embedded firmware validation and board-level testing. - Experience with microcontroller architectures and embedded logic. - Experience testing power electronics, inverters, or related electrical systems. - Strong Python programming skills for scripting, debugging, and test automation. - Experience with data collection, data analysis, and interpretation of validation results. - Experience documenting validation activities, test results, and engineering reports. - Strong troubleshooting and root cause analysis skills. - Excellent attention to detail and documentation practices.

Preferred

Qualifications - Experience working in an ISO 17025 accredited laboratory. - Experience with Battery Energy Storage Systems (BESS), renewable energy products, EV charging systems, or inverter technologies. - Familiarity with laboratory equipment such as oscilloscopes, logic analyzers, power analyzers, DAQ systems, programmable power supplies, and electronic loads. - Experience validating embedded firmware running on ARM, STM32, TI, NXP, Microchip, or similar microcontroller platforms. - Experience with communication protocols such as UART, SPI, I²C, CAN, or Modbus. - Experience building automated test frameworks for embedded hardware and firmware validation.

Salary Range - $110,000-130,000 - The actual salary offered is dependent on various factors including, but not limited to, location, the candidate's combination of job-related knowledge, qualifications, skills, education, training, and experience
