Job description

Description

We are ERock!

ERock is a leader and innovator in distributed energy. ERock has responded to long-term trends in electricity by becoming the first smart-grid supplier to US energy consumers. The company installs, operates, and integrates its highly flexible, low-cost, and quick-response distributed generation to increase reliability and stability, reduce costs and decrease carbon footprint.

At ERock, our backup generators ensure that customers will never be without power, allowing their business to operate normally when there is an outage in the area. Our innovative approach provides customers with highly reliable, ultra-clean backup generation at a fraction of the cost of traditional backup solutions. We seek those who share our commitment to customer service, innovation, and ingenuity.

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.

Requirements

Basic (Required) Qualifications:

• Minimum of five years of progressively responsible experience in automation, controls, electrical systems, commissioning, system integration, or a related industrial discipline.
• Bachelor's degree in electrical engineering, controls engineering, automation engineering, computer engineering, or a related technical field.
• Demonstrated experience with PLCs, industrial controllers, SCADA/HMI systems, industrial communications, instrumentation, control panels, and electrical/control-system documentation.
• Experience developing or reviewing control narratives, sequence logic, permissives, interlocks, alarm management, I/O lists, point mappings, functional test procedures, and commissioning records.
• Experience supporting FAT, SAT, startup, commissioning, troubleshooting, and turnover of industrial automation or electrical control systems.
• Ability to read and interpret electrical schematics, single-line diagrams, control wiring diagrams, P&IDs, network drawings, and vendor documentation.
• Ability to work safely and effectively in operating facilities, construction environments, electrical rooms, and active commissioning sites.
• Willingness and ability to travel to ERock project sites and provide field support, including occasional extended or nonstandard work schedules as project needs require.

• Experience with low-voltage and medium-voltage switchgear controls, breaker interlocks, protection interfaces, relay testing, and NETA or equivalent commissioning activities.
• Experience integrating GMCs, generator controllers, PLCs, SCADA, RTACs, protection relays, communications networks, and hardwired control interfaces.
• Experience leading first-of-kind controls development or converting custom project solutions into standardized designs, templates, or logic libraries.
• Experience with laboratory simulation, hardware-in-the-loop testing, signal injection, or controls validation before field deployment.
