How to Apply for Senior SCADA & Communications Engineer

at SMA America

🏢 About SMA America

SMA America is a global leader in solar inverter technology and energy management solutions, with a strong commitment to driving the transition to renewable energy. Their focus on utility-scale systems and grid integration makes them a key player in enabling a sustainable, climate-friendly future. Working here means contributing to cutting-edge projects that have a direct impact on global energy independence.

About This Role

This role is critical for ensuring the seamless integration and operation of SCADA systems across large-scale renewable energy assets. You will design and secure communication networks that connect site controllers, inverters, and cloud platforms, directly enabling real-time monitoring and optimization. Your work will support the reliability and efficiency of utility-scale solar and storage installations.

💡 A Day in the Life

A typical day might start with reviewing system alerts from cloud-based dashboards and troubleshooting communication issues with site controllers. You could then join a call with a utility to discuss secure data exchange requirements, followed by designing network segmentation for a new solar farm. Afternoons might involve configuring firewalls or VLANs, collaborating with O&M teams on performance optimization, and documenting compliance measures for NERC CIP audits.
