SW Engineeer - HIL Testing

We are partnering with an expanding energy storage firm focused on innovative battery technology. They are seeking a Software Engineer to develop the testing architecture required to validate their Battery Management Systems (BMS) prior to commercial release.

Operating where hardware meets software, you will develop simulation environments for Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) testing. These systems enable the team to evaluate how control electronics behave under various conditions without requiring a physical battery for every iteration.
