About the role

  • Lead the architectural design of site-level control systems, ensuring high-speed, reliable coordination between multiple LGens and balance-of-plant equipment
  • Design and implement robust communication interfaces using OPC-UA, Modbus, and other industrial protocols to ensure interoperability
  • Own the vision for our SCADA systems and HMI design, focusing on intuitive operator interfaces and deep diagnostic visibility
  • Develop strategies for integrating Mainspring technology into Distributed Energy Resource Management Systems (DERMS) and complex microgrid environments
  • Act as the subject matter expert for the engineering team on commercial power standards, site safety logic, and grid compliance
  • Work closely with Product and Hardware teams to translate utility requirements and interconnection standards into software specifications

Requirements

  • 8+ years of experience in commercial power generation, industrial automation, or utility-scale energy projects
  • Deep hands-on experience with SCADA, HMI, and industrial controllers (PLCs/PACs). Expert proficiency in IEC 61131-3 for local machine control. Additionally, a strong preference for candidates experienced in IEC 61499 to design event-driven, distributed architectures that enable seamless coordination across decoupled site assets
  • Expert-level understanding of OPC-UA, MQTT, Modbus, DNP3 (Pub/Sub, Client/Server) and its application in secure industrial environments
  • Proven track record of designing control logic for complex power sites (e.g., microgrids, peaking plants, or large-scale solar + storage)
  • Ability to draft high-level system diagrams and technical specs that bridge the gap between "industrial hardware" and "modern software"
Benefits
