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.
