Power Systems / Electrical Engineer - Inverter & Battery Systems



Location: San Mateo,CA

Type: 6-12 monthsContract

Rate:$75/hr on c2c

Working Conditions: Hybrid (4 days in office, 1 day remote)

Client:Zola Eletric


Need Someone With

  • Strong background in power systems and electrical engineering.

  • Hands-on experience with inverter-to-battery integration (5 kVA - 25 kVA capacity, 5 kWh - 50 kWh battery systems).

  • Proven system-level debugging experience (not just wiring or power flow).

  • Practical exposure to high-voltage products in laboratory environments.

  • Firmware (FW) development and debugging experience in relevant energy systems.



Roles & Responsibilities

  • Participate in design and development of high-power solar/battery control systems.

  • Modify software in a Linux embedded environment.

  • Handle prototype bring-up, debugging, hardware bug tracking, functional verification, and signal characterization.

  • Develop and execute hardware and system test plans, including pre-compliance, environmental, and reliability testing.

  • Work directly with Contract Manufacturers in Asia and component suppliers to ensure quality deliverables.

  • Contribute to DFMEAs, Design for Quality (DFQ), and Design for Reliability (DFR).

  • Develop numerical simulations and data analysis techniques to support creation of control algorithms and decision-support software.

  • Create peer-to-peer energy sharing and demand-response schemes.

  • Prototype preventive maintenance decision-support software.

  • Develop methods to size energy systems under demand uncertainty.

  • Design fault diagnosis and failure prognosis algorithms.



Key Qualifications

  • Bachelor's degree in Electrical Engineering (Master's preferred).

  • 5+ years of electrical design experience with digital, analog, and power electronic systems.

  • Deep knowledge of power conversion systems (converter, rectifier, inverter concepts).

  • Experience with Embedded Linux development, Device Trees, and Linux build systems (e.g., Buildroot).

  • Prior experience with solar or microgrid systems.

  • Extensive hands-on experience with lab instruments (oscilloscopes, spectrum analyzers, electronic loads, signal generators).

  • Experience developing digital/analog interfaces for PC-based test systems (Labview, Matlab-Simulink-Simscape, Altium, PLECS, Python).

  • Proficiency with numerical simulation software.

  • Familiarity with wireless technologies (Cellular, WiFi, Bluetooth).

  • Knowledge of XIL product development frameworks (MIL, SIL, PIL, HIL).

  • Familiar with international safety and EMC regulations (UL, ISO, IEC, FCC, NEC).

  • Strong written and verbal communication skills.

  • Ability to thrive in a fast-paced, start-up / high-growth environment.



Physical Requirements

  • Ability to lift and carry items weighing up to 25 pounds.

  • Ability to stand, walk, and move around for extended periods.

  • Ability to climb ladders or stairs and work at heights.
