    • 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 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

Form CC-305

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
