Design, develop, test, integrate, and commission control software, PLC/HMI, and SCADA solutions for energy storage and power infrastructure. Implement control algorithms, CI/CD and version control, support FAT/SAT, troubleshoot systems on-site and remotely, ensure compliance with standards, and collaborate across electrical, mechanical, firmware, and field teams.
ON.energy is building the power infrastructure that makes the AI era possible. As AI demand surges past what the grid and traditional data centers can support, ON.energy provides a new class of power technology proven at gigawatt scale and trusted by the world’s leading cloud and AI companies. Our systems are already deployed across 2.5 GW of hyper-scale campuses, validated by top U.S. national labs, and certified for grid-safe operation by major utilities. With real products in the field, we’re scaling faster than the grid can, transforming power from a bottleneck into a competitive advantage for the companies building the future.
The Software & Controls Engineer is responsible for the design, development, testing, integration, and commissioning of control software and automation systems that ensure the reliable, efficient, and safe operation of energy storage systems and power infrastructure projects.

Key Responsibilities
- Design, model, and implement control algorithms and control strategies for energy storage systems and power infrastructure.
- Contribute to system architecture discussions and define control strategy requirements and functional specifications.
- Design, develop, and maintain PLC, HMI, and embedded/control software for energy storage and distributed energy systems.
- Configure, integrate, and maintain SCADA systems for BESS and power infrastructure projects.
- Write clean, efficient, maintainable, and well-documented code following best practices.
- Build automation scripts, testing tools, simulation environments, and continuous integration pipelines.
- Implement version control, software documentation, and CI/CD workflows.
- Collaborate with electrical, mechanical, firmware, and field service teams to ensure full system functionality and seamless integration.
- Support the selection, configuration, and integration of control hardware, including controllers, relays, meters, and network devices.
- Conduct Factory Acceptance Tests (FATs) and Site Acceptance Tests (SATs).
- Diagnose and resolve issues related to control logic, real-time execution, PLC/SCADA behavior, and system performance, both remotely and on-site.
- Ensure compliance with cybersecurity requirements and relevant standards and codes (e.g., UL, IEEE, NFPA).
- Support installation, commissioning, field deployments, and ongoing operational troubleshooting.
- Interface with clients, vendors, and internal stakeholders to provide technical documentation, training, and ongoing support.
Requirements
- Bachelor’s degree in Electrical Engineering, Controls, Software Engineering, or a related field, or equivalent experience.
