POSITION OVERVIEW

The Senior Grid Modeling Engineer serves as a subject-matter expert in power system modeling and grid-integration analysis of SMA's utility-scale photovoltaic and battery energy storage solutions. The role provides modeling expertise to support the U.S. Application Engineering team, supplying analytical inputs required to conduct dynamic and steady-state studies, electromagnetic transient analysis, and comprehensive interconnection and regulatory compliance evaluations using industry-standard simulation models. Success in this position requires a strong foundation in power system engineering, advanced proficiency with simulation tools such as PSS/E, PSCAD/EMTDC, and TSAT, and deep technical insight into inverter-based resource behavior and control. The ideal candidate brings strong analytical rigor, a collaborative approach, and the ability to work effectively across U.S. and global teams.
PRIMARY DUTIES / RESPONSIBILITIES

- Serve as a subject-matter expert in the modeling and analysis of utility-scale solar, storage, and hybrid power plants, supporting the U.S. Application Engineering team across multiple SMA America projects and applications.

- Interpret ISO/TSO interconnection requirements (e.g., ERCOT, MISO, CAISO, ISO-NE, NYISO, PJM, SPP) and recommend appropriate SMA control configurations and parameter tuning, delivering customized models aligned with project-specific scopes.

- Maintain and manage versions of SMA's model portfolio across PSS/E, PSCAD/EMTDC, TSAT, and other simulation platforms used in the North American market.

- Provide technical support to the U.S. Application Engineering team by troubleshooting model functionality and executing simulation studies to validate dynamic model behavior against design specifications.

- Analyze inverter control modes and plant-level control strategies -- including their interactions in solar, storage, and hybrid system configurations -- and support model validation testing, benchmarking activities, and interconnection study workflows.

- Prepare comprehensive modeling study reports, technical documentation, and project deliverables that clearly communicate simulation findings and recommendations for IBR integration projects.

- Evaluate the impact of inverter-based resources on power system stability and propose technically sound mitigation strategies using SMA's technology portfolio.

- Act as a liaison between the U.S. Application Engineering team and SMA's Global Competence Center, ensuring effective communication and alignment on modelin
