Job summary

Castelion is seeking an experienced Industrial Chemical Engineer to lead the scale‑up of wet chemistry processes from laboratory development to pilot and full‑scale manufacturing. This role is critical to transitioning a proven laboratory reaction into a safe, reliable, and economically viable production process.

The engineer will design equipment, select scale-up strategies, optimize processes, and ensure operational readiness while handling hazardous chemicals in a fast-paced development

Qualifications

• Bachelor’s degree in Chemical Engineering.
• 8+ years of experience in chemical manufacturing, process engineering, or industrial process scale-up.
• Demonstrated experience scaling chemical reaction processes from laboratory or pilot scale to commercial production.
• Strong background in industrial wet chemistry operations involving hazardous chemicals.
• Experience with chemical reactors, mixing systems, chemical handling equipment, pumps, piping systems, and process controls.
• Knowledge of process safety management (PSM), hazard analysis methodologies, and chemical process safety principles.
• Ability to work independently in a hands-on engineering environment and drive projects from concept through implementation.

Responsibilities

• Lead the scale-up of laboratory-developed chemical reaction processes into pilot and production-scale operations.
• Develop scale-up methodologies, process models, and engineering calculations to support commercialization efforts.
• Design, specify, and commission reactors, mixing systems, chemical delivery systems, and associated process equipment.
• Evaluate reaction kinetics, mass transfer, heat transfer, mixing, and fluid flow considerations during process scale-up.
• Conduct process hazard analyses (PHA), and risk assessments for hazardous chemical operations.
• Establish safe operating limits and process control strategies for industrial-scale chemical reactions.
• Lead troubleshooting and root-cause investigations related to process performance, yield, quality, and equipment reliability.
• Collaborate with chemists, technicians, operations personnel, and leadership to optimize manufacturing processes.
• Develop batch records, work instructions, standard operating procedures (SOPs), and manufacturing documentation.
• Support facility design, equipment installation, commissioning, and operational qualification activities.
• Ensure compliance with all environmental, health, and safety (EHS) requirements and applicable regulatory standards.
