Experience delivering capital projects through engineering, procurement, construction, commissioning, and startup. Experience as an electrical discipline lead, project technical lead, or owner’s engineer. Experience overseeing EPC firms, consultants, equipment suppliers, system integrators, and construction contractors. Strong knowledge of industrial power distribution through 480 VAC and working knowledge of medium-voltage systems. Experience with substations, transformers, switchgear, MCCs, motors, VFDs, protective relays, grounding, and industrial electrical infrastructure. Working knowledge of process instrumentation, control valves, analyzers, PLC systems, remote I/O, and industrial control networks. Ability to review P&IDs, instrument data sheets, I/O lists, loop diagrams, control narratives, cause-and-effect matrices, single-line diagrams, and vendor drawings. Understanding of instrumentation power, grounding, shielding, signal segregation, intrinsic safety, and hazardous-area installation requirements. Experience reviewing electrical-system studies, specifications, RFQs, technical bid evaluations, and construction packages. Knowledge of applicable NEC, NFPA, IEEE, ANSI, ISA, UL, OSHA, and hazardous-area requirements. Experience supporting electrical and instrumentation construction, testing, loop checks, energization, commissioning, and startup. Strong technical leadership, communication, organization, and problem-solving skills. Ability to manage multiple projects and priorities. Preferred Qualifications Experience managing multiple EPC or engineering contractors. Experience with medium-voltage systems rated 4.16 kV or higher. Experience with ETAP, EasyPower, SKM, AutoCAD Electrical, or similar tools. Familiarity with Rockwell ControlLogix, Siemens, Codesys, or similar control platforms. Familiarity with Ethernet/IP, Modbus TCP/RTU, Profibus, Profinet, HART, and other industrial communication protocols. Experience specifying pressure, temperature, flow, level, analytical, and control-valve applications. Experience reviewing safety instrumented functions, shutdown logic, alarm rationalization, and packaged-equipment controls. Experience with FAT, SAT, relay testing, instrument calibration, loop checks, MOC, PHA, HAZOP, and PSSR. Experience in advanced recycling, chemical processing, refining, plastics, renewable fuels, or related industries. Key Competencies Strong electrical engineering judgment with practical instrumentation and controls knowledge. Ability to evaluate EPC and vendor engineering for completeness, quality, integration, and constructability. Ability to identify gaps between process requirements and electrical, instrumentation, and control-system designs. Ability to balance safety, reliability, operability, cost, and schedule. Strong commercial awareness and stakeholder communication. Ability to lead through influence in a fast-paced, multidisciplinary environment. ** Johnson Service Group (JSG) is an Equal Opportunity Employer.
