• 6–10 years of experience in chemical manufacturing, process operations, or process scale-up.
• Demonstrated experience supporting manufacturing operations and process scale-up activities.
• Demonstrated success scaling chemical processes from pilot to manufacturing scale.
• Experience working with highly reactive, air- and moisture-sensitive chemical systems is preferred.
• Demonstrated experience designing, specifying, commissioning, or improving chemical process equipment and unit operations.
• Familiarity with large-scale production equipment and unit operations.
• Experience supporting chemical manufacturing operations and commissioning new process equipment.
• Must be legally authorized to work in the United States now and in the future without the need for employer sponsorship.
• Ability to successfully complete a pre-employment drug test.

Preferred Qualifications

• Experience leading or supervising manufacturing personnel.
• Prior involvement in commissioning or startup of new chemical processes or facilities.
• Experience working with external equipment vendors, OEMs, or engineering firms on custom process equipment.
• Experience with SPC tools, data analysis, and process capability metrics (Cp/Cpk).
• Exposure to or experience implementing MES and/or LIMS systems in a manufacturing or lab environment.
• Experience designing or implementing chemical process equipment including reactors, distillation systems, evaporation systems, filtration systems, or other unit operations.
• Strong problem-solving skills and ability to operate effectively in a fast-paced production environment.

Physical Requirements

• Ability to wear a respirator (upon training/certification) and standard PPE as required.
• Ability to move 55-gallon drums using appropriate equipment.
• Ability to perform precise manipulations in a glovebox environment.
• Ability to sit or stand for extended periods of time.
• Ability to perform computer-based data entry, analysis, and presentations.
• Full-time onsite role (40 hours/week; typical schedule Monday–Friday, 8:00 AM – 5:00 PM).
• Occasional weekend work may be required to support manufacturing operations.
• Minimal travel expected.
