Senior Staff Engineer - Power Systems & Site Control

Mainspring Energy is revolutionizing power generation with innovative technology and is seeking a Technical Lead & Architect to define the future integration of their Linear Generators into the global energy infrastructure. This role involves leading the architectural design of site-level control systems and ensuring seamless integration with Microgrids and Distributed Energy Resources.

Responsibilities:

• Site Architecture: Lead the architectural design of site-level control systems, ensuring high-speed, reliable coordination between multiple LGens and balance-of-plant equipment
• Protocol Mastery: Design and implement robust communication interfaces using OPC-UA, Modbus, and other industrial protocols to ensure interoperability
• SCADA & HMI Development: Own the vision for our SCADA systems and HMI design, focusing on intuitive operator interfaces and deep diagnostic visibility
• DER Integration: Develop strategies for integrating Mainspring technology into Distributed Energy Resource Management Systems (DERMS) and complex microgrid environments
• Technical Mentorship: Act as the subject matter expert for the engineering team on commercial power standards, site safety logic, and grid compliance
• Cross-Functional Leadership: 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
• 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'
• Experience with grid interconnection standards (e.g., IEEE 1547, UL 1741)
• Knowledge of cybersecurity frameworks for industrial control systems (NERC CIP, etc.)
• Background in Python or C++ for high-performance industrial applications
