EMS Deployment Engineer

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.

Role Overview

The EMS Deployment Engineer is responsible for deploying, configuring, and supporting Ignition-based Energy Management Systems (EMS) for utility-scale Battery Energy Storage System (BESS) projects. This role plays a critical part in commissioning, ensuring reliable system visibility, control, data flow, and integration between EMS, PLCs, PCS, BMS, and site networks.

Key Responsibilities

• Deploy, configure, and support Ignition-based EMS/SCADA platforms for BESS projects
• Support commissioning activities including EMS bring-up, system integration testing, SAT, and early operational support
• Configure Ignition gateways, tags, UDTs, alarms, historian, and visualization components
• Integrate EMS with Siemens PLCs, PCS, BMS, meters, protection relays, and site networks
• Support data acquisition, control workflows, and site-level dashboards for commissioning and operations
• Troubleshoot EMS, data, and communications issues under commissioning timelines
• Collaborate closely with Controls Engineers, Network Engineers, Deployment Engineers, and Field Commissioning teams
• Support FATs, site commissioning, and handover to Service and Operations teams
• Assist in developing standardized EMS templates, screen sets, tag models, and deployment procedures
• Review and validate EMS documentation, configurations, and as-built deliverables
• Travel to project sites during deployment and commissioning phases as required

Required Qualifications

• Hands-on experience deploying and supporting Ignition (Inductive Automation) in OT or industrial environments
• Experience configuring tags, UDTs, alarms, historians, and visualization in Ignition
• Experience integrating EMS/SCADA platforms with PLCs and field devices
• Strong understanding of OT systems and industrial communications
• Ability to troubleshoot across EMS, controls, and networking boundaries
• Comfortable working in fast-paced commissioning environments with evolving requirements
• Willingness to travel to project sites as required
• Direct, hands-on Ignition deployment experience is required.

Preferred Experience

• Experience with utility-scale BESS, renewables, power generation, or substation environments
• Familiarity with Siemens PLCs and Modbus TCP / IEC 61850 (high-level understanding)
• Experience supporting commissioning teams on live sites
• Knowledge of OT cybersecurity fundamentals
• Experience working with EPCs, OEMs, and customer stakeholders

What Success Looks Like (First 6–12 Months)

• Ignition-based EMS systems are deployed reliably across new BESS projects
• Commissioning timelines are supported through stable EMS visibility and control
• EMS-related issues are identified and resolved quickly during site bring-up
• EMS configurations become more standardized and repeatable across projects
• Field, commissioning, and service teams trust this role as the EMS authority

What You’ll Get

• Competitive salary performance bonus

• 401(k) match, health, vision, dental

• Paid time off and company holidays

• Work that matters—building resilient, secure infrastructure for the future of energy
