Embedded Software Engineer 2 - HIL Verification & Electrification (119593-1)

The Embedded Software Engineer 2 will support the verification and validation of embedded controls and software for advanced electrification systems used in mobile equipment and stationary power applications. This role focuses on developing, maintaining, and operating Hardware-in-the-Loop (HIL) simulation environments using MATLAB/Simulink, OPAL-RT, and dSPACE to identify software and controls issues early in the development lifecycle. The engineer will create automated regression tests, analyze software behavior, and collaborate with embedded controls and software development teams to validate new features and support software releases. The ideal candidate will have experience with MATLAB/Simulink, programming or scripting, and embedded systems testing, along with a strong willingness to learn new HIL technologies and control systems., * Develop and maintain real-time electrification plant models using MATLAB/Simulink to support embedded controls verification and Hardware-in-the-Loop simulation.

• Configure, operate, troubleshoot, and maintain OPAL-RT and dSPACE HIL test benches, including hardware, harnesses, software configurations, and test environments.
• Develop requirements-based HIL test plans and test cases, create automated regression tests using Python or similar programming languages, and execute manual and automated software release testing.
• Analyze test results, investigate software and controls failures, document defects, and collaborate with embedded software and controls engineers to reproduce issues, debug functionality, and verify corrective actions.
• Support CAN/J1939 communication diagnostics, fault injection, ECU integration testing, and HIL bench commissioning while maintaining test traceability, documentation, and standardized verification processes.
