Job description

Nexus Circular - Sr Instrumentation & Controls Engineer - Atlanta

Role Overview

Nexus Circular is seeking a Senior Instrumentation & Controls Project Engineer to serve as the technical lead and primary interface for instrumentation, automation, and controls on capital projects, facility expansions, and process upgrades.

Reporting to the Electrical Engineering Manager, this position will lead I&C activities from conceptual design through engineering, procurement, construction, commissioning, startup, and project closeout. The engineer will coordinate EPC firms, system integrators, equipment suppliers, contractors, and multidisciplinary Nexus teams. The role requires basic electrical engineering knowledge to manage power, grounding, motor-control, and packaged-equipment interfaces associated with instrumentation and controls.

Responsibilities

• Serve as Nexus's I&C project lead and owner's technical representative for assigned capital projects.
• Establish design criteria, scopes of work, battery limits, deliverables, schedules, and technical acceptance requirements.
• Lead and coordinate work performed by EPC firms, consultants, system integrators, vendors, and contractors.
• Develop and review:
• o P&IDs, instrument indexes, data sheets, and I/O lists.
• o Instrument layouts, installation details, loop diagrams, and cable schedules.
• o Control narratives, operating sequences, and cause-and-effect matrices.
• o PLC, HMI, remote I/O, and industrial-network architectures.
• o Alarm, interlock, permissive, and shutdown requirements.
• Select and specify process instruments, analyzers, control valves, actuators, and related accessories.
• Review instrument ranges, sizing, accuracy, materials, process connections, environmental ratings, and hazardous-area suitability.
• Coordinate instrument power, grounding, shielding, signal segregation, intrinsic safety, surge protection, and cable routing.
• Ensure control-system designs properly implement process requirements, operating philosophies, alarms, interlocks, permissives, and shutdown functions.
• Coordinate interfaces between plant control systems and packaged equipment, motor controls, safety systems, and industrial networks.
• Provide basic electrical engineering support for 120/480 VAC power distribution, MCC and VFD interfaces, control panels, UPS/DC systems, grounding, and heat tracing.
• Review single-line diagrams, load lists, wiring diagrams, equipment data sheets, and cable-sizing calculations as they relate to I&C systems.
• Prepare and review specifications, RFQs, technical bid evaluations, vendor submittals, RFIs, deviations, and field changes.
• Monitor engineering progress and identify design gaps, interface conflicts, long-lead items, and cost or schedule risks.
• Evaluate project deliverables for technical accuracy, completeness, integration, constructability, operability, and commissioning readiness.
• Support construction walkdowns, installation inspections, FAT, SAT, calibration, loop checks, I/O verification, functional testing, commissioning, and startup.
• Participate in PHA, HAZOP, MOC, PSSR, constructability, and commissioning-readiness reviews.
• Verify final project documentation reflects the installed and commissioned system.
• Mentor engineers and designers and provide technical direction across multidisciplinary teams.
• Travel approximately 10%-20%, depending on project requirements.

Required Qualifications

• Bachelor's degree in Electrical Engineering, Instrumentation Engineering, Controls Engineering, or a related discipline from an ABET-accredited program.
• Seven or more years of instrumentation and controls experience in chemical, petrochemical, energy, manufacturing, or a related process industry.
• Experience delivering capital projects through engineering, procurement, construction, commissioning, and startup.
• Experience serving as an I&C discipline lead, project technical lead, or owner's engineer.
• Experience managing technical interfaces among EPC firms, system integrators, vendors, contractors, and internal stakeholders.
• Strong knowledge of process instrumentation, analyzers, control valves, PLCs, HMIs, remote I/O, and industrial networks.
• Experience developing and reviewing P&IDs, instrument data sheets, I/O lists, loop diagrams, control narratives, and cause-and-effect matrices.
• Knowledge of instrument grounding, shielding, signal segregation, intrinsic safety, and hazardous-area installations.
• Basic knowledge of industrial electrical systems through 480 VAC, including MCCs, motors, VFDs, control panels, UPS/DC systems, and grounding.
