• Develop and evaluate process chemical and specialty gas-related design concepts for semiconductor and advanced technology facilities, including cleanroom support systems, bulk chemical delivery, waste collection, and associated utility interfaces.
• Perform engineering calculations, equipment sizing, pressure drop analyses, flow evaluations, and material compatibility reviews to support safe and efficient process system design.
• Prepare and review process flow diagrams, PFDs, P&IDs, equipment layouts, line sizing studies, and narrative descriptions that define system intent and operational requirements.
• Coordinate closely with mechanical, electrical, structural, architectural, controls, and fire protection teams to resolve spatial conflicts, utility tie-ins, access requirements, and operational constraints.
• Ensure designs align with applicable codes, standards, and client requirements.
• Participate in client meetings, technical discussions, and design reviews to confirm scope, validate assumptions, and align deliverables with project goals, schedule, and budget.
• Support vendor and equipment integration by reviewing datasheets, submittals, utility requirements, and connection details for process tools, chemical storage systems, and supporting infrastructure.
• Apply QA/QC procedures to engineering deliverables, ensuring technical accuracy, code compliance, consistency across drawings and specifications, and adherence to SSOE standards.
• Conduct site walks, field verifications, and punchlist support as needed to confirm existing conditions, assess installation progress, and support turnover planning.
• Develop and maintain clear technical documentation, calculations, and correspondence that support multidisciplinary coordination and client communication throughout the project lifecycle.
• Identify constructability, safety, operability, and maintainability concerns early in design and recommend practical solutions that reduce project risk and improve long-term performance.
• Mentor junior staff when appropriate by sharing technical knowledge, reviewing work products, and reinforcing disciplined engineering practices.

Required Qualifications:

• Bachelor’s degree in Chemical Engineering, Mechanical Engineering, or a related discipline.
• 3–6 years of relevant experience in process engineering, preferably within a design-build or EPC environment.
