Job Overview
Mainspring Energy is looking for a Technical Lead & Architect to define the future of how our Linear Generators integrate into the global energy infrastructure. You will be the primary architect for commercial-grade site control systems, ensuring our technology seamlessly integrates with Microgrids, Distributed Energy Resources (DERs), and utility-scale power plants.
You aren’t just writing code; you are designing the communication and control backbone that allows our generators to play nicely with solar, storage, and the grid.
Key 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
Core Requirements
- Industry Experience: 8+ years of experience in commercial power generation, industrial automation, or utility-scale energy projects
- Systems Expertise: 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
- Deep Protocol Knowledge: Expert-level understanding of OPC-UA , MQTT, Modbus, DNP3 (Pub/Sub, Client/Server) and its application in secure industrial environments
- Site Design: Proven track record of designing control logic for complex power sites (e.g., microgrids, peaking plants, or large-scale solar + storage)
- Architectural Fluency: Ability to draft high-level system diagrams and technical specs that bridge the gap between "industrial hardware" and "modern software"
Preferred Skills
- 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
