Job description

About the role

We are looking for a System Architect / Senior System Design Engineer to lead the hardware architecture and system-level design of utility-scale PV inverters and Battery Energy Storage System (BESS) Power Conversion Systems (PCS). The role requires strong hands‑on expertise in power‑converter design, system architecture, electrical integration, and product development from concept through certification and field deployment.

Key responsibilities

• Define system architecture and hardware design for utility‑scale PV inverters and BESS PCS in the MW power range.
• Develop power‑stage architecture, including power semiconductors, DC‑link, AC filter, busbars, magnetic components, and protection systems.
• Design and optimize high‑power inverter / PCS hardware, including thermal management, switching strategy, efficiency, power density, and reliability.
• Develop grid‑connected and grid‑forming (GFM) converter architectures, including grid synchronization, fault ride‑through, reactive power, and power‑quality requirements.
• Design DC and AC interfaces for PV, battery, transformer, and grid connections, including isolation, protection, and grounding.
• Lead system‑level electrical design, including SLDs, operating modes, ratings, overload capability, and fault‑current withstand.
• Coordinate with control, firmware, mechanical, thermal, EMC, and certification teams to ensure successful product integration.
• Support component selection, derating, reliability analysis, and design reviews for power semiconductors, capacitors, inductors, transformers, and protection devices.
• Develop and review design calculations, simulations, prototypes, and validation plans for power‑conversion systems.
• Lead DVT/PVT, type testing, EMC/EMI, safety, and certification activities for IEC/UL‑compliant products.
• Support field issue resolution, root‑cause analysis, and product improvement through engineering changes.
• Contribute to new product platforms, technology roadmaps, and intellectual property development for PV, BESS, and microgrid applications.

Required technical expertise

• Strong experience in power‑electronics system architecture and hardware design.
• Hands‑on experience with utility‑scale PV central inverters and/or MW‑class BESS PCS.
• Good understanding of 2‑level / 3‑level inverter topologies, high‑power switching devices, and converter modulation.
• Experience in DC‑link design, AC filters, magnetic components, busbars, protection, and thermal design.
• Knowledge of grid‑connected inverter control concepts, including GFL, GFM, LVRT/HVRT, reactive power control, and grid‑code requirements.
• Experience with electrical simulations and design tools such as MATLAB/Simulink, PLECS, PSIM, or equivalent.
• Understanding of EMI/EMC, insulation coordination, creepage/clearance, grounding, and safety requirements.
• Familiarity with IEC / UL standards applicable to PV inverters, PCS, and power‑conversion equipment.
• Ability to interpret and prepare system specifications, SLDs, interface documents, and technical design reviews.

Education

Bachelors or Masters degree in Electrical Engineering, Power Electronics, or a related field.

Preferred experience

• Experience in MW‑class converter development, including 1 MW–5 MW PV inverters or PCS.
• Experience with grid‑forming PCS, islanded operation, seamless transfer, and parallel operation.
• Experience in BESS system integration, battery DC interfaces, and energy‑storage applications.
• Exposure to HIL validation, PSS®E / PSCAD studies, grid‑code compliance, and utility‑scale project commissioning.
• Experience in UL certification, type testing, and international product development.
• Experience in design leadership, technical mentoring, and cross‑functional project execution.
