Hanwha Q CELLS Co., Ltd., is one of the world´s largest and most recognized photovoltaic manufacturers for its high-performance, high-quality solar cells and modules. It is headquartered in Seoul, South Korea (Global Executive HQ) and Talheim, Germany (Technology & Innovation HQ). Through its growing global business network spanning Europe, North America, Asia, South America, Africa, and the Middle East, the company provides excellent services and long-term partnerships to its customers in the utility, commercial, government, and residential markets. Hanwha Q CELLS is a flagship company of Hanwha Group, a FORTUNE Global 500 firm and a Top 7 business enterprise in South Korea.
Our mission is to provide affordable and smart energy solutions through technology and innovation to create a sustainable future for the planet. We are expanding our business by offering revolutionary energy systems to residential customers including ESS, MLPE (power optimizers, micro-inverters), EV charging solutions, and Smart IoT with world-class solutions.
This position is responsible for hardware/ electrical design for renewable (PV) energy products (inverters, EV chargers, energy storage, and system communication). You are a highly capable individual contributor, who can evolve to be a team builder as we continue our accelerated growth. You are responsible for leading the review and analysis of system requirements, executing, and evaluating designs, performing circuit analysis, part selection, capturing schematics, overseeing PCB layout, estimating BOM cost, supporting the build of successful prototypes, and leading complex engineering projects through the development phases to meet the requirements. Demonstrate the ability to plan, define, and execute the hardware development for energy electronic products with no supervision.


  • Analyze requirements and map them into an HW architecture,
  • Lead the HW design throughout the product life cycle from concept to mass production.
  • Electronic system architecture definition, design, and collaboration with 3rd party partners
  • Perform hardware bring-up and integration of electronic circuits including controllers, power processing subsystems, communication, RF, high-speed interfaces, board power tree, and hardware/FW integration.
  • Work with PCB layout engineer, antenna engineer, and mechanical engineer to implement optimized PCB layouts with compliance to EMC & manufacturing design rules.


  • Bachelor of Science (BS) degree in Electrical Engineering from an accredited university.
  • Minimum of 7 years of industry or university research experience in developing, testing, and troubleshooting electronics design for PCBAs.
  • Strong experience in RF design including selection of RF parts such as transceivers, antennas, RF switches, connectors, termination, and design for noise.
  • Strong experience in calculating, evaluating, and measuring link budget and propagation for narrowband and broadband signals, modulation schemes, and SNR estimation.
