Job Description:

We're seeking a I&C Engineer to lead major process controls engineering projects spanning digital control systems (PLC/DCS/HMI), complex test stands, and chemical processes. You will take problems from issue to solution, setting expectations for data-driven decision making, automation, and the responsible use of AI/agentic AI to improve workflows, reduce rework, and deliver cost-effective, compliant designs. This role blends hands-on engineering (design, fabrication, assembly, programming, testing) with technical leadership, client engagement, and rigorous software configuration management.

Key Responsibilities:

Digital Systems & Controls Engineering

* Engineer and integrate PLC, DCS, HMI, network switches, and control systems; lead programming and commissioning for Allen-Bradley platforms (ControlLogix/CompactLogix, Studio 5000, FactoryTalk).

* Implement robust controls architectures, safety interlocks, alarming, data logging, recipe management, and historian integrations for test and process systems.

Instrumentation Specification & Systems Design

* Develop Functional Requirements and Procurement Specifications for instrumentation and control components and systems.

* Prepare design input documentation for drawings including cable block diagrams, wiring schematics, loop sheets, and detailed I/O maps.

* Help in creating and maintaining P&IDs and System Design Descriptions (SDDs).

Vendor Coordination & Technical Documentation

* Interface with vendors; prepare and review equipment purchase specifications.

* Produce clear, concise technical reports and engineering studies.

Configuration Management & Quality

* Establish and enforce software configuration management (SCM) for PLC/HMI code, scripts, and documentation.

* Review design drawings and documentation produced by others.

Leadership in Automation & AI/ML

* Direct processimprovement initiatives: automate calculations, summarize technical documents, generate design documentation, and guide when/how AI or agentic AI tools are used.

* Oversee engineering automation via Python, MATLAB, or advanced Excel; review and validate automated outputs.

* Champion responsible integration of AI/ML into controls systems, including predictive maintenance and anomaly detection.

Required Qualifications:

* B.S. or M.S. in Engineering from an ABET accredited program.

* 5+ years of experience in design engineering for process control systems.

* Hands on expertise with Rockwell/AllenBradley PLCs and FactoryTalk systems.

* Experience designing, fabricating, assembling, programming, and testing test stands and chemical process systems.

* Strong SCM proficiency including Git, versioning, and code reviews.

* Excellent communication skills and experience reviewing design drawings.

* Active DOE Q Clearance or eligibility to obtain.

Preferred Qualifications:

* Master's degree in a related engineering field.

* Experience with PlantPAx, FactoryTalk Analytics, OPC UA, historians, and industrial networking.

* Familiarity with SIS, PHA, ISA standards, and NFPA/NEC codes.

* Experience integrating AI/ML into industrial systems.

* Additional learning such as CS, AI, or Software Engineering certificates or minors.
