Sr Electrical Engineer – EV Power Systems & Energy Integration

Key Responsibilities

• Design, develop, and validate medium-voltage(12–2000V) electrical subsystems for use in EV power platforms and stationary energy solutions.
• Specify and integrate components including inverters, converters, power distribution units, transformers, AC-DC and DCDC power modules, charging systems, lithium and sodium batteries, power distribution panels, and harnesses/connectors.
• Ensure all designs comply with relevant industry standards and certifications, including UL1973, UL508, UL9540A, and applicable grid codes.
• Conduct electrical system-level calculations including load flow, short-circuit, fault protection, thermal analysis, and grounding strategies.
• Interpret AC grid requirements and apply system-level knowledge to the integration of CSI products into customer applications.
• Create and maintain technical documentation, including schematics, interface specifications, wiring diagrams, test plans, and validation reports.
• Support testing and commissioning activities, including field validation, issue troubleshooting, and system optimization.
• Participate in cross-functional collaboration with mechanical, software, and controls engineers, as well as suppliers and customers.
• Support cost estimation, BOM development, and trade-off analysis for component selection and system design.
• Provide mentorship and technical guidance to junior engineers and technicians as required.
• Maintain awareness of emerging industry standards, energy technologies, and competitive systems.

Qualifications

• Bachelor's degree in Electrical Engineering or other technology related field required. Master’s or higher degree preferred.
• Minimum 5 years (7-10 desired) of professional experience in medium-voltage electrical system design or energy system integration.
• Knowledge of high-power electrical systems for both mobile and stationary applications
• Experience working with battery energy storage systems (BESS), microgrids, and high-power vehicle charging systems
• Knowledge of medium voltage 600-1000V safety and design standards
• Experience with commercial EVs, heavy-duty vehicle electrification, or mobile power systems.
• Exposure to renewable energy systems (solar, wind, generator hybrid)
• Familiarity with UL certification processes, including UL1973, UL9540A, and UL508.
• Proficiency in electrical design tools and simulation platforms (e.g., AutoCAD Electrical, PLECS, Simulink, MATLAB).
