• Design, qualify, troubleshoot, and support PLC and SCADA architectures in partnership with controls engineering, including backup support for site control systems. 

• Apply robust Management of Change practices to ensure process and equipment changes are evaluated, documented, implemented, and sustained in compliance with safety and quality requirements. 

• Mentor, coach, and develop manufacturing engineers by providing technical guidance, feedback, and opportunities to build leadership depth across the team. 

• Provide operational leadership in the Senior Manager’s absence by keeping critical initiatives moving and serving as a trusted point of contact for Operations, Quality, Maintenance, and cross-functional partners. 

What We Seek 

• Bachelor's degree in chemical engineering, or related field. 

• 5–10 years of hands-on experience in process engineering or manufacturing engineering, preferably in a high-tech manufacturing or industrial environment. 

• Proven ownership of capital projects, including scope development, budget management, vendor coordination, installation, validation, and production handoff. 

• Strong project management capability, including schedule ownership, risk mitigation, cross-functional alignment, and contractor or supplier management. 

• Working knowledge of Management of Change practices and the ability to apply structured change control in a manufacturing environment. 

• Strong automation fundamentals with experience or exposure to PLC, SCADA, HMI, or batch process control systems; GE Proficy iFIX, ISA S88, or advanced PLC programming experience is a plus.
