At SSOE, we don’t just talk about the future, we build it. As a leader in industry AI adoption, we empower our team to work smarter by providing responsible access to the industry leading AI Large Language Models, vibe-coding platforms, and securely integrating advanced tools into every role. From day one, you’ll receive the training and support needed to leverage AI as a core tool for enhancing productivity, sparking creativity, and streamlining complex workflows.

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-mar
