Position Summary:

• The Commissioning Engineer is a field-capable technical engineer responsible for the design, integration, testing, commissioning, and troubleshooting of automation and controls systems used in ERock's distributed generation and microgrid projects. This role partners closely with the Commissioning Manager, A&C engineers, commissioning technicians, project engineering, EPC, O&M, NOC/SCADA, protection specialists, and customers. The position focuses on unique and medium-voltage sites, advanced controls integration, and converting first-of-kind solutions into repeatable standards and field-ready packages.

Key Responsibilities:

• Serve as a technical A&C partner to the Commissioning Manager, providing engineering support, field guidance, and timely escalation for complex commissioning issues.
• Develop, review, and maintain control narratives, sequence-of-operation documents, permissive and interlock matrices, alarm lists, command and feedback definitions, point lists, I/O databases, Modbus maps, and controls test procedures.
• Lead or support automation and controls commissioning for unique, medium-voltage, and advanced microgrid projects, including generator controls, GMCs, PLCs, SCADA, RTACs, protection interfaces, communications networks, and switchgear controls.
• Review electrical schematics, control wiring, termination schedules, panel drawings, network architectures, controller files, and vendor documentation for completeness and field readiness.
• Participate in design reviews, factory acceptance testing, site acceptance testing, pre-commissioning, functional testing, integrated system testing, startup, performance testing, and turnover activities.
• Troubleshoot controls, communications, sequencing, protection, indication, and system-integration issues in the office, laboratory, and field; identify root causes and implement durable corrective actions.
• Work directly with commissioning technicians to translate engineering intent into clear, executable field procedures, checklists, test scripts, and verification steps.
• Support the Commissioning Manager with readiness reviews, prerequisite tracking, technical planning, staffing estimates, field mobilization, and closeout of commissioning deliverables.
• Coordinate with Engineering, EPC, project management, O&M, NOC/SCADA, third-party protection and testing providers, equipment manufacturers, and customers to resolve technical interfaces and field constraints.
• Provide technical leadership for first-of-kind controls work, including documenting design decisions, validating assumptions, capturing lessons learned, and developing reusable templates, logic standards, and commissioning packages.
• Support controls simulation, hardware-in-the-loop, and laboratory testing initiatives intended to reduce field discovery and improve commissioning readiness.
• Maintain accurate redlines, as-left controller files, test records, issue logs, punch lists, and turnover evidence in accordance with ERock standards.
• Support post-commissioning troubleshooting and operational handoff, including technician and operator training when required.
• Promote safe work practices, quality execution, disciplined change control, and professional communication with customers and internal teams.
• Other responsibilities as directed by supervisor.
