About the Role

As a Software Validation Engineer, you will design and maintain Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) environments to stress-test power electronics and site controllers. Your mission is to build automated frameworks that catch edge cases before they hit the field, ensuring product reliability.

Responsibilities

• Architect and scale SIL and HIL environments using platforms like Typhoon HIL, Opal-RT, or similar.
• Lead the development of automated test suites in Python to transition validation processes to a fully automated framework.
• Define and execute comprehensive Verification and Validation (V&V) plans.
• Integrate automated HIL/SIL testing into CI/CD pipelines.
• Design custom interface hardware and wiring for HIL benches.
• Debug complex failures found during validation using logic analyzers, oscilloscopes, and telemetry logs.

Requirements

• BS or MS in Electrical Engineering, Computer Engineering, or a related field.
• 2+ years of professional experience in software validation or test automation for hardware-focused systems.
• Proven experience with real-time simulation platforms (Typhoon HIL, Opal-RT, or dSPACE).
• Deep understanding of how to model power electronics components in a virtual environment.
• Expert proficiency in Python (specifically for test automation frameworks like Pytest).
• Familiarity with Rust and C/C++ to navigate embedded codebases.
• Comfortable in a high-voltage lab environment.
• Proficient with standard lab equipment (oscilloscopes, power supplies, electronic loads).
• Familiarity with digital protocols like CAN, SPI, and Ethernet.
• Dedicated mindset for "breaking" software and a track record of finding critical edge cases.
• Experience with Git, Jenkins/GitHub Actions, and containerization tools like Docker.
