About the role:We are building the next generation of solid-state, grid-interactive power blocks that enable high-density, flexible power delivery for datacenters, renewable energy systems, and advanced microgrids.
The Simulation Engineer is responsible for developing, maintaining, and validating component-level and system-level simulation models for Solid-State Transformers (SSTs) and microgrid architectures. The primary focus of the role is on MATLAB/Simulink-based modeling of power electronics, controls, and grid interaction, supporting product development, application engineering, and system validation.
This role collaborates closely with application, and standards engineers, providing simulation insight to guide architecture decisions, control strategy development, and performance validation across a range of grid-connected and microgrid use cases. Data center and DER-enabled applications represent key but not exclusive deployment scenarios.
Key ResponsibilitiesSystem-Level Modeling & Simulation

HIL (Hardware-in-the-Loop) Simulation Support
- Work closely with Hardware-in-the-Loop(HIL) teams
- Adapt and deploy models for real-time execution in HIL environments
- Collaborate with controls and test teams to:
- Validate control firmware against simulated plant models
- Exercise fault, protection, and corner-case scenarios safely
- Correlate HIL results with offline simulations and hardware testing
- Support debugging and refinement of models based on HIL and lab feedback
Grid Interaction & Standards-Driven Analysis
- Simulate grid interaction scenarios relevant to US interconnection expectations, supporting analysis aligned with standards such as:
- IEEE 1547 / IEEE 1547.1 (as applicable)
- Provide simulation evidence to support:
- Design reviews
- Certification and compliance readiness
- Utility and customer technical evaluations
