How to apply for Senior SCADA and Communications Engineer

About SMA America

SMA America is the U.S. subsidiary of SMA Solar Technology AG, a solar inverter manufacturer operating since 1981 with over 1,500 patents and a presence in over 190 countries. It offers inverter solutions for every system size, from residential rooftops to large-scale utility plants. The company's stated focus is global energy independence and a climate-friendly future, with a culture built on autonomy, clear expectations, and open door leadership.

About the role

This role owns SCADA and communications engineering for solar inverter and photovoltaic power plant systems. The work covers the data and control layer that connects inverters to grid operators and plant monitoring, which is central to making PV plants reliable and cost effective. The position is remote or based in Rocklin, California, or Texas, and reports into a company that builds solutions for every system size, so the communications scope likely spans residential through utility-scale plants.

A typical day

A typical day may involve configuring or troubleshooting communications between solar inverters and SCADA or monitoring systems, reviewing network and protocol settings, and coordinating with field or grid-side teams on data or control issues. The posting does not describe the daily routine or team structure, so ask about on-call expectations, travel, and how remote engineers collaborate with the Rocklin and Texas teams.

Who SMA America is looking for

• Has hands-on SCADA engineering experience in power generation, renewables, or utility environments, including configuring and troubleshooting communications between field devices and control systems.
• Knows industrial communication protocols used in solar and grid settings, such as Modbus, DNP3, IEC 61850, or SunSpec, and can work with network hardware, RTUs, and gateways.
• Has worked with solar inverters or photovoltaic power plants and understands how plant data flows to utilities, grid operators, or monitoring platforms.
• Is authorized to work in the United States on a full-time basis, as stated in the job posting, and can work remotely with occasional travel to Rocklin or Texas as needed.

Tips for this application

• Name the specific SCADA protocols and platforms you have used in your resume, not just 'SCADA experience'. SMA's inverters connect to grid and monitoring systems, so Modbus, DNP3, IEC 61850, or SunSpec references matter.
• Quantify the scale of systems you have supported. State the MW capacity, number of inverters, or number of sites you have worked with, since SMA serves residential through utility-scale plants.
• Address your work authorization status clearly in the application, because the posting states applicants must be authorized to work in the United States on a full-time basis.
• State your location and willingness to work remote, in Rocklin, or in Texas. The posting lists the location as pending confirmation, so removing ambiguity helps.
• Reference SMA products or the solar inverter space in your materials. Showing you know SMA's role as an inverter manufacturer, not just SCADA in general, separates you from generic applicants.

What to cover in your cover letter

Explain how your SCADA and communications work directly connects inverters or power plant equipment to grid operators and monitoring systems. Describe the protocols and hardware you have configured in production environments. Give one example of a communications problem you diagnosed and fixed at a solar or power generation site. State your location and work authorization so the company can confirm logistics quickly.

Research before applying

• Review SMA America's product lines, including Sunny Central, Sunny Boy, and Sunny Tripower, and note which are used in utility-scale versus residential systems.
• Read about common SCADA and communications requirements for solar PV plants, including grid operator interconnection rules and protocols like SunSpec and DNP3.
• Look into SMA Solar Technology AG's global operations and the 1,500 patents mentioned in the posting to understand the company's technical depth.
• Check SMA America's Rocklin, California headquarters and any Texas operations to understand where the team is based and how remote work is handled.

Likely interview topics

Based on the job description, expect questions about:

• Which SCADA and communication protocols have you configured in production, and how did you troubleshoot them when data stopped flowing?
• How have you integrated solar inverters or similar power equipment into a SCADA or utility control system?
• Walk through a time you diagnosed a communications failure between field devices and a control center. What was the root cause and fix?
• How do you handle the security and network requirements for remote or distributed power plants?
• What do you know about SMA's inverter portfolio and how SCADA requirements differ across residential, commercial, and utility-scale systems?

Common mistakes to avoid

• Listing SCADA as a skill without naming protocols, platforms, or equipment you have actually configured. For this role, generic SCADA claims are easy to screen out.
• Ignoring the work authorization requirement. The posting is explicit, so failing to confirm your status creates doubt.
• Submitting a resume focused on IT or general networking without tying it to power generation, inverters, or PV plants. The role sits in the energy space, not general IT.
