Quick Summary

  • Lead design and development of microgrid systems with renewable energy and high-voltage distribution.
  • Develop and optimize system architectures for EV/UXV charging and bidirectional power systems.
  • Plan and execute system testing including lab, HIL, and field trials for charging and microgrid systems.

Full Description

Responsibilities: Lead the design and development of microgrid systems integrating renewable energy, hybrid sources, energy storage, and high‑voltage distribution for fixed and mobile platforms. Develop and optimize system architectures for EV/UXV charging infrastructure, fast charging, and bidirectional power systems (V2G/V2L/V2V). Perform detailed sizing, selection, and integration of batteries, inverters, chargers, DC/DC converters, and energy management systems. Develop and implement control strategies for microgrid operation—load sharing, synchronization and power quality management. Plan and execute system testing & validation, including lab testing, hardware‑in‑the‑loop (HIL), and field trials for charging and microgrid systems. Work closely with cross-functional engineering teams to ensure electrical integration with vehicles, platforms, and supporting infrastructure. Conduct root-cause analysis and provide engineering solutions to technical issues in HV components, power distribution, or charging systems. Prepare documentation, including schematics, system diagrams, test procedures, design reports, and technical presentations. Support prototyping, commissioning, and deployment, including hands-on troubleshooting when required. Requirements: Bachelor’s or Master’s degree in Electrical Engineering, Power Engineering, Mechatronics, or a related field. 5–7 years of experience in high‑voltage power electronics, EV charging systems, or advanced electrical systems. Strong technical knowledge in microgrid architecture, energy storage and BMS, power electronics, EV/UXV charging technologies, bidirectional power systems, and renewable energy sources. Proficiency in modelling and simulation tools (MATLAB/Simulink or AMESIM). Skilled in interpreting electrical schematics, wiring diagrams, and integration schematics. Knowledge of electrical protection, earthing, harmonics, and power quality fundamentals. Hands-on experience with HV systems testing, commissioning, and troubleshooting. Strong problem‑solving skills, with the ability to handle complex multi‑disciplinary issues. Effective communicator with the ability to collaborate across different engineering domains. Independent, resourceful, and adaptable, with a strong drive to learn and innovate. Class 3 driving license preferred.
