You will develop real-time HIL models, integrate hardware with HIL platforms, and drive cross-functional validation activities in a fast-paced team environment. The role focuses on HIL-based validation for UPS, AC-DC and DC-DC converters, with hands-on experience in MATLAB/Simulink, Stateflow, and OPAL-RT.

Qualifications

• Hands-on experience with HIL testing and validation of power converters; OPAL-RT experience preferred.
• Strong experience in MATLAB/Simulink and Stateflow model development.
• Understanding of power electronics systems (UPS, AC-DC and DC-DC converters).
• Knowledge of power converter control algorithms and state machines.
• Experience in controller-to-HIL interfacing, signal mapping, and I/O configuration.
• Ability to debug hardware-software integration in real-time simulation environments.
• Knowledge of control systems, embedded controllers, and validation methodologies.
• Experience with real-time simulation and model-based design.
• Exposure to firmware validation and embedded system testing.
• Strong analytical and problem-solving skills for cross-functional teams.

Responsibilities

• Design and develop breakout/interface boards for integrating power converter controllers with HIL platforms.
• Configure and establish Hardware-in-the-Loop (HIL) test setups using OPAL-RT for power electronic systems such as UPS, DC-DC converters, AC-DC converters, inverters, and related products.
• Develop and maintain real-time HIL models for power circuits and associated interface circuits using MATLAB/Simulink and Stateflow.
• Integrate power converter control hardware with the HIL environment, including: Signal conditioning and gain setting; Pin mapping and wiring validation; Analog and digital I/O configuration; Communication interface setup and verification.
• Execute validation activities as per Design Verification Test (DVT) plans provided by Control Engineering teams.
• Analyze test results, document observations, and generate validation reports.
• Diagnose and troubleshoot issues identified during HIL testing and collaborate with Control, Firmware, and System Engineering teams to drive resolution.
• Support controller algorithm verification, fault injection testing, and system-level validation activities.
