Aligned with global partners who seek proven scalable solutions to meet ambitious plastic circularity goals, Nexus Circular is rapidly expanding its innovation footprint worldwide, moving decisively to address the complex challenges of plastics accumulation in the environment.

Nexus has built an outstanding culture. We are looking for people to contribute to a fast-paced, environmentally committed business that is focused on growth and sustainability. We are very collaborative, transparent, data driven, value diverse perspectives and are looking for constructive initiatives and new ideas. We are looking for self-starters and independent thinkers who work collaboratively in teams. Given the growth stage of Nexus, we are also looking for people who are comfortable moving between strategic thinking and executing those ideas to take Nexus to the next level.

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
