Job description

Job Description: Senior Power Electronics HIL Engineer (Opal-RT Specialist)

Location:

Bangalore

Experience:

4-5 Years (Automotive)

Education:

B.E./B.Tech in EE/E&C (M.Tech in Power Electronics preferred) from Tier-I institute

About The Role

We are seeking a Senior HIL Engineer specializing in high-fidelity real-time simulation for our next-generation EV systems. Unlike traditional HIL roles, this position focuses on the high-speed dynamics of 400V Traction Inverters, OBCs, and DC-DC converters. You will be the technical point for integrating complex MATLAB/Simulink plant models into the Opal-RT environment, ensuring high-fidelity execution at the nanosecond scale.

Responsibilities

• System Integration: Integrate individual high-fidelity MATLAB/Simulink models (Inverter, Motor, OBC, DC-DC) into a unified X-in-1 plant model.
• Real-Time Optimization: Deploy and optimize models on Opal-RT (RT-LAB) using the eHS (Electrical Hardware Solver) to support high switching frequencies for high switching converters.
• Advanced Modeling: Implement dynamic thermal models for SiC MOSFETs/IGBTs based on real-time loss equations (conduction and switching losses).
• FPGA Management: Execute CPU vs. FPGA partitioning to ensure sub-microsecond solver steps without overruns.
• Hardware Interfacing: Define and manage I/O mapping between the control PCB and Opal-RT cards (Analog, Digital, and high-speed PWM acquisition).
• Test Automation: Develop comprehensive HIL automation frameworks using Python and Vector CANoe (CAPL).
• Safety Validation: Design and execute HIL test cases for ASIL-D safety mechanisms, simulating faults like Over-Voltage, Over-Current, and Gate Driver failures.
• Data Analysis & Reporting: Analyze complex log files and HIL traces to identify root causes of defects. Generate detailed test reports and dashboards.
• Executive Summaries: Translate technical test data into Executive Summary reports, highlighting software maturity, risk areas, and project KPIs for management review.

Eligibility

• Tool Expertise: Expert of Opal-RT (RT-LAB, eHS) is mandatory. Professional experience with MATLAB/Simulink and Stateflow.
• Power Electronics Depth: Good understanding of semiconductor physics and power electronics topologies.
• HIL Automation: Proficiency in Python for HIL API control and Vector tools (CANoe, CANalyzer) for bus simulation and UDS diagnostics.
• Hardware Savvy: Ability to read schematics and understand signal conditioning for PWM, BNC instrumentation, and interfacing with high-voltage programmable DC sources/loads.
• Safety Standards: Hands‑on experience implementing ISO 26262 functional safety test cases in a HIL environment.

Desirable

• M.Tech in Power Electronics or Electric Drives.
• Experience with high-fidelity motor model integration.
• Experience in the startup ecosystem or developing X-in-1 powertrain architectures.
