About The Position
Mainspring Energy is seeking a highly skilled Staff Controls Software Engineer to develop and test the critical software that integrates our Linear Generators into global energy infrastructure. As an individual contributor (IC) within a high-performing Scrum team, you will focus on building commercial-grade site control systems, ensuring seamless integration with Microgrids, Distributed Energy Resources (DERs), and utility-scale power plants. You will be responsible for writing high-quality code, conducting rigorous testing, and collaborating with your team to deliver the communication and control backbone of our technology.
Requirements
- 8+ years of hands-on experience in commercial power generation, industrial automation, or utility-scale energy projects
- Expert proficiency with SCADA, HMI, and industrial controllers (PLCs/PACs)
- Deep hands-on experience with IEC 61131-3 for machine control
- Proven track record of developing and testing control logic for complex power sites (e.g., microgrids, large-scale solar + storage)
- Expert-level proficiency in OPC-UA, MQTT, Modbus, and DNP3 within secure industrial environments
- Experience with grid interconnection standards (e.g., IEEE 1547, UL 1741)
- Knowledge of cybersecurity frameworks for industrial control systems (e.g., NERC CIP)
- Ability to create clear technical documentation and system diagrams that bridge the gap between industrial hardware and modern software
Nice To Haves
- Strong preference for experience in IEC 61499 for event-driven architectures
- Experience with industrial serial protocols (like UART) is a plus
Responsibilities
- Design, implement, and test control system features, ensuring they are robust and scalable for a high-volume manufacturing environment
- Develop and maintain communication interfaces using OPC-UA, Modbus, and other industrial protocols to ensure system interoperability
- Build and refine SCADA systems and HMI designs, focusing on creating intuitive operator interfaces and deep diagnostic visibility for the team
- Work closely within a Scrum framework, participating in sprint planning, code reviews, and daily stand-ups to deliver reliable software increments
- Own the testing lifecycle for new features, including unit testing, integration testing, and hardware-in-the-loop (HIL) validation to ensure site safety logic and grid compliance
- Implement strategies for integrating Mainspring technology into Distributed Energy Resource Management Systems (DERMS) and complex microgrid environments
- Work with Product and Hardware teams to translate utility requirements and interconnection standards into functional software specifications
