About the Role:

The Senior Technical Solutions Engineer will play a key role in supporting the development, evaluation, and integration of utility-scale energy storage systems and related power solutions, with a focus on Power Conversion System (PCS), Energy Management System (EMS), medium-voltage transformer (MVT), microgrid, and gas turbine applications.

This position requires a systems-level understanding of electrical power systems, power electronics, and controls, with the ability to navigate both hardware and software engineering contexts. The ideal candidate will contribute to integration testing, internal tool development, solution validation, technical documentation, and cross-functional coordination across multiple products, suppliers, and teams.

For internally developed systems, the engineer will work closely with R&D and global engineering teams to provide direct input on design features, electrical interfaces, validation strategies, and integration requirements. For externally procured products, the focus will be on leading technical due diligence, confirming compatibility with the overall system architecture, supporting standards compliance, and transferring product knowledge to internal engineering, Applications, and Execution teams.

Responsibilities:

• Technical Due Diligence and Product Development Support
• Solution Development & Supply Chain Support
• Cross-functional Support and Customization

Required Qualifications and Skills:

• Bachelor’s degree in electrical engineering, power systems, controls engineering, or a related discipline; preference given to candidates with a postgraduate degree in engineering.
• Minimum 5 years of experience in engineering, R&D, or project commissioning within power electronics, energy storage, microgrids, power generation, or related industries.
• Direct experience in inverter product development, control systems, or energy storage project commissioning is strongly preferred.
• Strong general electrical-system knowledge, including power systems, power electronics, inverters, plant-level controls, transformers, medium-voltage equipment, protection, and system integration.
• Experience with Battery Energy Storage System (BESS) and microgrid applications, including electrical architecture, equipment interfaces, controls, and system integration.
• Experience with medium-voltage transformers and associated MV equipment, including equipment ratings, selection, sizing, protection, electrical interfaces, and system integration.
• Knowledge of gas turbine systems, including technical evaluation, equipment selection and sizing, operating characteristics, performance assessment, and integration within microgrid or power-system applications, is preferred.
• Familiarity with key standards and certifications related to inverter, EMS, MVT, microgrid, and integrated power-system applications, including applicable UL, IEEE, IEC, medium-voltage equipment, and grid-interconnection requirements.
• Experience collaborating with international partners, particularly engineering or manufacturing teams across global time zones.
• Demonstrated ability to lead or contribute to the development of internal engineering tools, system models, or automation processes.
• Strong technical, analytical, and troubleshooting skills, with a hands-on approach to product validation and integration.
• Proficiency in Mandarin is a plus but not required.
