Role Overview

Nexus Circular is seeking a Senior Electrical & Instrumentation Engineer to lead electrical engineering for capital projects, facility expansions, and process upgrades. You will support projects from concept development through engineering, procurement, construction, commissioning, startup, and closeout.

Reporting to the Electrical Engineering Manager, you will serve as Nexus's electrical technical representative when working with EPC firms, consultants, utilities, equipment suppliers, contractors, and internal project teams. Your instrumentation and controls responsibilities will focus primarily on electrical interfaces and coordination.

Key Responsibilities

• Serve as electrical discipline lead and owner's technical representative for assigned capital projects
• Establish electrical and instrumentation design criteria, scopes of work, technical requirements, deliverables, and acceptance criteria
• Direct and review work performed by EPC firms, consultants, vendors, system integrators, and construction contractors
• Develop and review calculations, specifications, data sheets, RFQs, technical bid evaluations, drawings, and construction packages
• Lead the design and integration of:
• Medium- and low-voltage power distribution
• Substations, transformers, switchgear, and switchboards
• MCCs, motors, VFDs, panelboards, relays, and circuit breakers
• UPS, battery, DC, emergency, and standby power systems
• Grounding, lightning protection, heat tracing, lighting, and receptacle systems
• Review load-flow, motor-starting, short-circuit, coordination, arc-flash, grounding, and cable-sizing studies
• Evaluate existing electrical-system capacity and identify required upgrades for new process loads
• Review P&IDs, instrument indexes, I/O lists, instrument data sheets, loop diagrams, control narratives, and cause-and-effect matrices
• Support the selection and specification of process instruments, including pressure, temperature, flow, level, analytical, and final control elements
• Coordinate instrumentation power, grounding, signal segregation, cable routing, junction boxes, remote I/O, and hazardous-area requirements
• Review PLC, HMI, control-panel, industrial-network, and packaged-equipment interfaces for technical completeness
• Coordinate with controls engineers and system integrators on interlocks, alarms, permissives, shutdowns, and equipment sequences
• Coordinate electrical and instrumentation requirements with process, mechanical, piping, civil/structural, construction, operations, safety, and procurement teams
• Review EPC schedules, document registers, technical deviations, field changes, and change-order proposals
• Support vendor inspections, Factory Acceptance Testing, construction walkdowns, loop checks, Site Acceptance Testing, energization, commissioning, and startup
• Review RFIs, test reports, relay results, calibration records, loop folders, and commissioning documentation
• Participate in MOC, PHA, HAZOP, constructability, PSSR, and commissioning-readiness reviews
• Identify technical, procurement, cost, and schedule risks and recommend corrective actions
• Ensure compliance with Nexus standards and applicable NEC, NFPA, IEEE, ANSI, ISA, UL, OSHA, utility, and hazardous-area requirements
• Mentor engineers and designers
• Travel approximately 10–20%, depending on project requirements

Required Qualifications

• Bachelor's degree in Electrical Engineering from an ABET-accredited program
• Seven or more years of electrical and instrumentation engineering experience in chemical, petrochemical, energy, manufacturing, or a related process industry
• 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
