HIL Simulation Engineer

About the RoleSungrow 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 ResponsibilitiesTechnical Leadership & Grid ComplianceDesign, 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 SupportGenerate 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 SupportPerform 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.RequirementsEducation & ExperienceBachelor’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 ExpertiseStrong 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 / BonusExperience 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 RequirementCandidates must be fluent in either English or Chinese. Bilingual proficiency in both is a strong advantage.Travel RequirementRegional and international travel may be required to support project coordination, lab activities and stakeholder engagement.Why Join Sungrow?This is a high-impact technical role in a growing regional lab focused on real-time simulation technology. You will work at the forefront of renewable energy grid integration, combining deep simulation expertise with real customer projects and global collaboration. If you are a technical expert ready to bridge the gap between regional execution and headquarters strategy, we want to hear from you.
