Staff Power Systems Site Integration Engineer

Mainspring Energy manufactures fuel-flexible, low-emissions local power solutions. The Staff Power Systems Site Integration Engineer owns site-level readiness after construction, validating integration of mechanical, electrical, control, and communication systems before commissioning and operation.

Responsibilities:

• Interpreting technical project details, including scopes of work, sequences of operation, control narratives, and engineering drawings (site plans, P&IDs, single-line, and three-line diagrams), and serving as the controls subject matter expert in design reviews
• Verifying relay settings, meter configurations, and controller programming delivered by third-party integrators against approved settings files and design documents
• Owning site readiness on assigned projects by validating installation quality and accuracy of balance-of-plant systems such as fuel, electrical, metering, protection relays, and communications; developing punch lists and driving issues to closure when discrepancies are found
• Validating electrical and mechanical installations against drawings and specifications by witnessing and/or reviewing results of checks such as wiring and termination verification, grounding, insulation resistance and continuity testing, phase rotation, and electrical acceptance test (NETA) reports; and equipment setting and anchoring, gas piping pressure and leak tests, purging, ventilation and exhaust, and fuel regulator setup
• Configuring equipment and verifying functional readiness of site-level control and communication systems prior to energization, including troubleshooting industrial communication networks (e.g., Modbus TCP/IP, EtherNet/IP, Profibus, OPC-UA)
• Supporting integration with customer PLC/SCADA/HMI platforms (e.g., Ignition, SEL RTAC, Siemens WinCC, AVEVA Wonderware, Rockwell FactoryTalk, Schneider EcoStruxure) for system monitoring and control
• Coordinating handoff to the generator commissioning team, confirming all site-level prerequisites are complete before units are started, and keeping project stakeholders updated on readiness status and next steps
• Planning Site Acceptance Testing (SAT) and system-level validation, defining acceptance criteria for customer and utility witness testing, and confirming that as-built operation matches design intent
• Supporting Permission to Operate (PTO) by compiling documentation based on utility requirements and building an accurate submission package for the Interconnection team to issue to the utility
• Owning site QA/QC documentation and ensuring systems are fully validated and ready for turnover to operations and the customer
• Establishing repeatable processes, including ready-for-commissioning and ready-for-testing checklists, lookahead dashboards, SAT templates, equipment configuration and how-to guides, site procedures, etc
• Travelling to project sites as needed to confirm readiness and perform necessary testing

Requirements:

• B.S. degree in Electrical, Controls, Mechatronics, or a related engineering discipline. Equivalent field experience may be substituted
• 5+ years in pre-commissioning, site commissioning, field applications, or controls engineering on power generation, battery storage, solar, microgrid, or industrial facility projects
• Experience configuring, integrating, and troubleshooting devices and platforms such as:
• Protective relays and automation controllers: SEL (relays, RTAC), GE Multilin, Beckwith, or ABB
• Revenue and power quality meters: SEL-735, Schneider ION, GE kV2c, or Itron
• PLCs: Allen-Bradley ControlLogix/CompactLogix, Siemens S7, or Schneider Modicon
• SCADA/HMI: Ignition, Siemens WinCC, AVEVA (Wonderware), or Rockwell FactoryTalk View
• Working knowledge of industrial communication protocols (Modbus TCP/IP, EtherNet/IP, Profibus, OPC-UA, DNP3) and OT networking
• Ability to interpret single-line and three-line diagrams, P&IDs, control narratives, and sequences of operation
• Understanding of balance-of-plant systems, including fuel/gas, low- and medium-voltage electrical, metering, protection, and communications, with the ability to read construction plan sets and acceptance test reports and a working knowledge of NEC and NFPA 37/54
• Experience planning and documenting Site Acceptance Testing and supporting utility witness testing for PTO
• Familiarity with field safety practices and energization standards and procedures (e.g., NFPA 70E, lockout/tagout), including Lockout/Tagout (LOTO) procedures and arc flash hazard awareness
• Strong analytical problem-solving skills with the ability to safely use standard electrical test equipment (multimeters, phase rotation meter, network cable/fiber tester, power quality analyzers) in an active construction or live-plant environment
• Strong documentation and communication skills, and comfortable coordinating contractors, integrators, and customers on site
• Self-directed, with an ownership mindset and enthusiasm for building repeatable processes within a growing team
