Requirements

• Bachelor’s degree in Controls Engineering, Electrical Engineering, Computer Engineering, Mechanical Engineering, Mechatronics, Chemical Engineering, or a related technical discipline.
• 2-4 years of hands-on controls, automation, or process-control engineering experience in a process-industry environment. Relevant industries may include semiconductor, specialty gas, chemical, pharmaceutical, food and beverage, energy, water treatment, or other highly automated manufacturing operations.
• Demonstrated experience designing, programming, testing, commissioning, and troubleshooting PLC- and HMI-based industrial control systems.
• Working knowledge of instrumentation, process control, feedback loops, interlocks, permissives, alarms, sequencing, and industrial communication networks.
• Ability to create and interpret control narratives, functional specifications, I/O lists, P&IDs, electrical drawings, network diagrams, test protocols, and operating or maintenance documentation.
• Experience with structured software development, source/version control, peer review, defect tracking, release management, and controlled change processes.
• Strong written and verbal communication skills, sound engineering judgment, and the ability to collaborate effectively across disciplines and locations.
• Ability to analyze complex equipment and process issues, prioritize work, manage assignments with limited supervision, and deliver practical, maintainable solutions.

Nice To Haves

• Experience with Rockwell Automation Studio 5000 / RSLogix, Siemens TIA Portal, Schneider Machine Expert, or comparable PLC platforms; experience with industrial HMI/SCADA platforms such as FactoryTalk, Ignition, or GP-Pro EX is beneficial.
• Exposure to C, C#, Python, SQL, scripting, APIs, data historians, edge computing, or industrial data platforms is beneficial.
• Exposure to simulation, model-based systems engineering, digital twins, data analytics, machine learning, or AI-assisted engineering workflows is beneficial.
• Experience with high-purity gas systems, semiconductor equipment, hazardous processes, functional safety, or regulated manufacturing environments is beneficial.

Responsibilities

• Develop PLC, HMI, and industrial control solutions from requirements definition through design, programming, integration, testing, commissioning, and lifecycle support.
• Translate process requirements, P&IDs, sequence-of-operations documents, cause-and-effect matrices, and safety requirements into reliable control strategies for gas purification and material delivery systems.
• Specify and integrate controllers, industrial networks, instrumentation, analyzers, valves, drives, safety devices, panels, and supporting electrical hardware.
• Design controls that generate contextualized, trustworthy, and secure operational data suitable for diagnostics, analytics, digital twins, predictive insights, and future AI-assisted decision support.
• Develop alarm management, equipment health indicators, event logging, trending, and diagnostic functions that accelerate troubleshooting and support condition-based and predictive maintenance.
• Create and execute software test plans, simulation-based tests, factory acceptance tests, site acceptance tests, and commissioning procedures; document results and resolve issues systematically.
• Use process data and structured problem-solving methods to improve cycle time, stability, throughput, quality, energy use, maintainability, and equipment availability.
• Develop modular, scalable, and reusable software using established coding standards, libraries, templates, version control, and formal change-management practices.
• Partner with process, mechanical, electrical, software, manufacturing, quality, field service, suppliers, and customer-facing teams to deliver robust solutions.
• Apply approved industrial cybersecurity, access control, backup, recovery, documentation, and configuration-management practices throughout the control-system lifecycle.
• Troubleshoot hardware, software, communication, and process-control issues; perform root-cause analysis and implement sustainable corrective actions.
• Perform other duties as assigned in support of GMC and Entegris business priorities.

Benefits

• Generous 401(K) plan with an impressive employer match
• Excellent health, dental and vision insurance packages to fit your needs
• Flexible work schedule and 11 paid holidays a year
• Paid time off (PTO) policy that empowers you to take the time you need to recharge
• Education assistance to support your learning journey
