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.

Nice To Haves

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.
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.

Responsibilities

Lead and drive the process engineering design and planning for a portfolio of complex, advanced high-tech industrial and semiconductor projects, from conceptual design and process flow development through detailed piping and instrumentation diagrams (P&IDs), and construction administration within an integrated design-build delivery framework.
Provide technical leadership and day-to-day oversight to internal process engineering project teams, ensuring the production of coordinated, high-quality design documents (PFDs, P&IDs, equipment specifications, pipe routing plans, isometrics) that meet our client’s purity and safety specifications, SEMI standards, industry best practices, and project schedules.
Perform detailed engineering calculations related to fluid flow, pressure drop, heat transfer, and mass balance for systems including high purity water, specialty gases, and hazardous chemical handling.
Coordinate with in-house mechanical, electrical, controls, and structural disciplines to integrate system designs, resolving interface conflicts via integrated project delivery (IPD) methodology.
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.
