Job description

About the Role

Sungrow is expanding its advanced real-time simulation capabilities. We are seeking a highly technical HIL Simulation Engineer for the local Hardware-in-the-Loop (HiL) laboratory to strengthen our real-time simulation laboratory.

In this hands-on individual contributor role, you will focus on the validation and grid compliance certification of utility-scale BESS and PV inverters using real-time simulation platforms. You will serve as a key technical expert and bridge between regional teams, global R&D, Control Engineering, Technical Marketing, and Grid Compliance groups. A major part of the role involves using the regional lab to reproduce on-site issues, coordinate with headquarters, and drive timely technical resolutions.

We are looking for a strong technical expert with deep hands-on experience in real-time simulation and a proven track record in power system validation, grid interconnection, and project delivery.

Key Responsibilities

Technical Leadership & Grid Compliance

• Design, develop, and maintain CHIL and PHIL test environments using real-time simulation platforms.


• Lead verification and certification activities for BESS and PV inverter controls to comply with major international grid codes (IEEE 1547, VDE-AR-N 4110/4120, EREC G99, NEM, etc.).


• Develop and validate dynamic plant models, including inverter models, battery models, and Power Plant Controller (PPC) logic.


• Drive test automation using Python or similar tools to improve efficiency and repeatability.


• Serve as a high-level technical escalation point for complex control, communication (Modbus, DNP3, IEC 61850), and grid interconnection issues.


• Reproduce and analyze on-site problems in the regional lab, coordinate with headquarters, and ensure timely closure of technical issues.


• Lead end-to-end execution of regional semi-physical grid simulation projects and customer delivery projects.

Cross-Functional & Technical Marketing Support

• Generate simulation-backed data and reports to support technical marketing, white papers, and brand authority.


• Host laboratory visits and deliver real-time HIL demonstrations to customers, utilities, and key stakeholders.


• Collaborate with Sales and Technical solution engineering teams to provide expert technical input during bidding and project phases.

Laboratory Technical Support

• Perform hands-on testing and validation work in the state-of-the-art real-time HIL laboratory.


• Support efficient scheduling and utilization of test resources to meet project deadlines.


• Provide technical input on hardware/software needs and platform enhancements.

Requirements

Education & Experience

• Bachelor’s or Master’s degree in Electrical Engineering, Power Systems, Control Systems, or a related field.


• 5+ years of hands-on experience in real-time simulation, HIL testing, or inverter/BESS control validation.


• Demonstrated technical leadership on complex projects (strong individual contributor with influence).

Technical Expertise

• Strong proficiency with real-time simulation platforms and the ability to build, run, and troubleshoot complex models.


• Deep understanding of utility-scale PV inverters and BESS operation, control strategies, and grid behavior.


• Extensive experience with international grid codes and interconnection requirements (fault ride-through, voltage/frequency support, power quality, etc.).


• Strong programming skills in Python, C/C++, MATLAB/Simulink for test automation and model development.


• Familiarity with industrial communication protocols (Modbus TCP/RTU, DNP3, IEC 61850).

Preferred / Bonus

• Experience with plant-level (station-level) semi-physical simulation models.


• Joint commissioning experience with third-party systems such as EMS or SVG.


• Exposure to multiple real-time simulation platforms.

Language Requirement

Candidates must be fluent in either English or Chinese. Bilingual proficiency in both is a strong advantage.

Travel Requirement
