Job description

HIL ENGINEER Job Description: Senior Power Electronics HIL Engineer (Opal-RT Specialist) Location: Bangalore Experience: 4-5 Years (Automotive) Education: B.E./B.Tech in EE&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.
