Junior Simulation Engineer - EMS
ON.energy is setting the standard for large load interconnection. ON’s patented AI UPS™ is a medium-voltage UPS that serves as a firewall, protecting the data center from the grid, and the grid from the data center. With multiple gigawatts currently under construction, we are enabling grid-safe data centers.
Role Summary
At ON.energy, the Simulation Engineer for Battery Energy Storage Systems (BESS) is responsible for building, running, and validating simulation environments that ensure our energy management software performs correctly before it ever touches real hardware. This is a simulation-first role where the primary deliverables are high-fidelity Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) test environments that give our engineering teams confidence in every algorithm, control loop, and protection function we deploy.
The ideal candidate is an early-career engineer with a solid foundation in dynamic systems, power electronics, or control theory, and a hands-on curiosity for building models that accu
