How to apply for Senior Power Systems Modeling Engineer, Grid Integration

About SMA America

SMA America is the U.S. subsidiary of SMA Solar Technology AG, a solar inverter manufacturer founded in 1981. The company holds more than 1,500 patents and operates in over 190 countries, offering inverter solutions for every system size from residential rooftops to large utility plants. It is headquartered in Rocklin, California, and has helped U.S. homes, businesses, and utilities generate clean power for more than two decades.

About the role

This role focuses on power systems modeling for grid integration, likely supporting how SMA inverters interact with the electric grid. You would work on simulation, analysis, and compliance tasks that help solar and storage systems connect reliably to utility networks. The position is remote and full-time, so you would collaborate with teams across locations while doing hands-on modeling work.

A typical day

A typical day might involve running power system simulations in tools like PSCAD or PSS/E, reviewing grid code requirements, and documenting results for internal teams or utility customers. You would likely join virtual meetings with colleagues in Rocklin or other locations to discuss project status, troubleshoot modeling issues, or plan next steps for interconnection studies. Because the role is remote, you would manage your own schedule and communicate progress through written reports and online collaboration tools.

Who SMA America is looking for

• Has strong experience with power systems modeling tools such as PSCAD, PSS/E, or MATLAB/Simulink, especially for inverter-based resources.
• Understands grid codes, interconnection standards, and utility requirements for solar and storage projects in the U.S.
• Can analyze dynamic and transient behavior of inverter-based systems and communicate results clearly to engineers and utilities.
• Is self-directed and comfortable working remotely while coordinating with colleagues in different time zones.

Tips for this application

• In your resume, list specific modeling software you have used and the types of grid studies you performed, such as load flow, short circuit, or dynamic stability.
• Mention any experience with SMA products or competitor inverters, since the role is specific to grid integration of SMA equipment.
• Include examples of projects where you helped a solar or storage system meet a utility's interconnection requirements.
• If you have worked with U.S. grid codes like IEEE 1547 or NERC standards, name them explicitly in your application.
• Because the role is remote, briefly note your experience working independently or with distributed teams on technical projects.

What to cover in your cover letter

Explain why you want to work for a company that has been in solar inverter technology since 1981 and holds over 1,500 patents. Describe a specific grid integration project you worked on and what modeling tools you used. Connect your experience to SMA's range of solutions, from residential to utility-scale. State that you understand the remote nature of the role and can manage your own schedule while delivering technical work.

Research before applying

• Review SMA America's product lines, especially their utility-scale and commercial inverters, to understand what grid integration challenges they address.
• Look up recent SMA America press releases or project announcements to see what types of grid projects they are involved in.
• Read about U.S. interconnection standards such as IEEE 1547-2018 and NERC reliability guidelines for inverter-based resources.
• Check if SMA America has published any technical papers or white papers on grid modeling or inverter performance.

Likely interview topics

Based on the job description, expect questions about:

• Walk through a grid integration study you completed. What tools did you use and what was the outcome?
• How do you model inverter-based resources differently from traditional synchronous generators in power system studies?
• What U.S. grid codes and standards are most relevant to solar and storage interconnection, and how do you stay current with them?
• Describe a time you had to explain complex modeling results to a non-technical stakeholder or a utility engineer.
• Why do you want to work specifically at SMA America rather than another inverter manufacturer or renewable energy company?

Common mistakes to avoid

• Submitting a generic resume that does not mention specific power system modeling tools or grid codes relevant to inverter-based resources.
• Failing to show any knowledge of SMA America's products or history, which makes the application look like a mass submission.
• Ignoring the remote aspect of the role and not addressing how you stay productive and communicate in a distributed team.
