• Support construction administration and startup by reviewing shop drawings, addressing RFIs, evaluating submittals, and participating in site walks to validate installation against design intent.
• Conduct quality control checks and participate in peer reviews to ensure adherence to company procedures and regulatory standards before project deliverable submission
• Ensure code conformance throughout design and construction, proactively identifying potential compliance issues and developing effective, technically sound, and constructible solutions.
• Mentor junior and mid-level process engineers within internal project teams, fostering deep understanding of fluid mechanics, friction loss analysis, high-purity system design, gas and chemical safety, material compatibility, semiconductor industry standards, and the technical detailing required for reliable, contamination-free process utility systems.
• Contribute to the development and maintenance of process engineering standards, master specifications, P&ID symbol libraries, calculation templates, and documentation protocols to improve efficiency, consistency, technical quality, and speed-to-market across high-tech and semiconductor projects.

Required Qualifications:

• Bachelor’s degree in Chemical Engineering from an accredited institution, qualifying for professional engineer (PE) licensure in the state of practice, is required.
• Preference will be given to candidates who hold a Professional Engineering (PE) license. This credential may qualify candidates for the higher end of the salary range, depending on experience and overall qualifications.
• 10+ years of process engineering experience, with a strong and demonstrated focus on semiconductor, advanced high-tech industrial, cleanroom, or mission-critical facility design.
• Proficient in AutoCAD and Revit for process engineering deliverables, including 3D modeling and drafting for process piping systems is required.
• Demonstrated expertise in chemical process system design encompassing fluid transfer, heat exchange, specialty gas systems, and hazardous wastewater treatment.
• Strong working knowledge of P&ID development, control valve and instrumentation specification, and control philosophy documentation.
• Experience with the design and engineering of systems that consist of fluid transfer, heat exchange, friction loss in piping systems, ultrapure/high purity water systems, specialty gas and chemical systems, solvent/acid/hazardous wastewater treatment systems or other related systems.
• Experienced in conducting hydraulic calculations including friction loss analyses and pump sizing validated by recognized engineering methods.
• Excellent communication, presentation, and client-facing skills, with the ability to clearly articulate complex process engineering concepts, system P&IDs, and risk assessments to diverse audiences including engineers, managers, project managers, trades, and client technical leadership.
• Solid communication skills tailored for technical writing, client presentations, and interdisciplinary collaboration.

Preferred Qualifications:

• Direct experience with semiconductor fabrication facility process systems.
• Knowledge of sustainable process design practices, including UPW reclaim/recycle strategies, waste heat recovery, and chemical minimization initiatives.
• Demonstrated success working within an integrated design-build project delivery environment on large-scale, fast-track high-tech projects.
