How to apply for Senior Grid Modeling Engineer, Large Scale Grid Integration

About SMA America

SMA America is a global leader in solar inverter and energy storage solutions, driving the transition to renewable energy with cutting-edge grid integration technology. Working here means contributing to large-scale solar and storage projects that shape the future of energy independence, with a strong emphasis on innovation and sustainability.

About the role

This role is critical for ensuring utility-scale solar, storage, and hybrid plants can reliably interconnect with the grid. As a Senior Grid Modeling Engineer, you'll develop and maintain dynamic models in PSS/E, PSCAD, and TSAT, directly influencing how SMA's inverters and controls meet stringent ISO/TSO requirements.

A typical day

A typical day might involve running dynamic simulations in PSS/E to validate a solar plant's response to grid faults, then collaborating with the global R&D team to update model parameters based on new ISO requirements. You might also review interconnection study results and prepare technical documentation for a project's application engineering team.

Who SMA America is looking for

• Holds a master's or PhD in electrical engineering with a focus on power systems, and has deep expertise in inverter-based resource modeling.
• Has 5+ years of hands-on experience with PSS/E, PSCAD/EMTDC, and TSAT for utility-scale solar and storage projects.
• Understands grid-forming inverter technology and advanced battery storage controls, with experience in interconnection studies.
• Can interpret complex ISO/TSO requirements and translate them into practical control configurations and model updates.

Tips for this application

• Highlight specific projects where you developed PSS/E or PSCAD models for solar/storage plants that successfully interconnected.
• Mention any experience with grid-forming inverters or advanced storage controls, as this is a key differentiator.
• Quantify your impact: e.g., 'Developed models for 500 MW solar + storage plant that passed interconnection studies.'
• Show familiarity with SMA's product portfolio (e.g., Sunny Central inverters) and how they integrate with grid codes.
• Tailor your resume to emphasize collaboration with global teams and participation in industry working groups (e.g., IEEE, WECC).

What to cover in your cover letter

["Your passion for advancing grid integration of renewable energy and alignment with SMA's mission of energy independence.", "Specific examples of modeling work you've done for utility-scale solar/storage, especially with PSS/E and PSCAD.", 'Your ability to interpret and apply ISO/TSO interconnection requirements to real-world projects.', 'Experience working with cross-functional teams and contributing to industry standards or working groups.']

Research before applying

• Review SMA's inverter product lines (e.g., Sunny Central, Sunny Tripower) and their grid support features.
• Understand current interconnection requirements from major US ISOs like CAISO, ERCOT, or PJM.
• Read recent SMA white papers or case studies on large-scale solar/storage integration projects.
• Familiarize yourself with SMA's role in industry groups like the Solar Energy Industries Association (SEIA).

Likely interview topics

Based on the job description, expect questions about:

• Describe a challenging interconnection study you worked on and how you resolved modeling issues.
• How do you approach modeling grid-forming inverters in PSCAD? What are key differences from grid-following?
• Explain how you would update SMA's model portfolio to comply with a new ISO requirement.
• Tell us about a time you collaborated with a global team to deliver a customized model for a specific project.
• What industry trends in grid integration (e.g., IEEE 1547-2018, NERC MOD-026) impact your modeling work?

Common mistakes to avoid

• Submitting a generic resume that doesn't specifically address PSS/E, PSCAD, or TSAT experience.
• Overlooking the importance of grid-forming technology; ensure you highlight any relevant knowledge.
• Failing to demonstrate understanding of US-specific interconnection processes and ISO requirements.
