Your ability to inspire teams, build enduring client partnerships, and represent SSOE to stakeholders will drive office success and market growth. You will thrive in a collaborative, design-build environment where your technical expertise, business intelligence, and strategic problem-solving skills will be highly valued. This role offers the unique opportunity to work on technically complex, large-scale projects, lead and mentor internal engineering teams, represent the firm externally, and directly contribute to the success of our leading semiconductor clients and the sustained growth of our firm in this dynamic, high-growth sector. AI and Innovation 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 Technical Leadership & Project Delivery Lead and drive the process engineering design and planning for a portfolio of complex, large-scale advanced high-tech industrial and semiconductor projects from conceptual design and process flow diagram (PFD) development through detailed piping and instrumentation diagrams (P&IDs), and construction documentation, within an integrated design-build delivery framework. Provide technical leadership and day-to-day oversight to internal process engineering project teams, ensuring the creation of coordinated, high-quality design documents (PFDs, P&IDs, equipment specifications, pipe routing plans, isometrics) that meet our client’s purity, safety, and performance specifications, industry best practices, and project schedules. Lead and support the design of systems such as ultra-pure water (UPW) systems, specialty gas distribution systems, chemical distribution systems, etc. Develop and oversee detailed hydraulic calculations for piping systems, including friction loss analysis, pump and heat exchanger sizing, NPSH calculations, pressure drop across filters and point-of-use equipment, thermal expansion/contraction of double-contained piping, and surge analysis to ensure system performance under varying demand profiles. Guide the seamless integration of process systems with a multidisciplinary team, collaborating with all engineering disciplines to ensure coordination, constructability, and operational performance. Perform and oversee process system modeling using industry-standard software, including steady-state and transient hydraulic analysis, heat transfer calculations, and pipe stress analysis to validate design integrity. Lead peer reviews, quality assurance/quality control checks, and constructability reviews, with a particular focus on P&ID accuracy, material compatibility, piping slope and drainage for high-purity systems, pressure test strategies, and adherence to client and industry standards. Mentor junior and mid-level process engineers within internal project teams, fostering deep understanding of fluid mechanics, high-purity system design, gas and chemical safety, material compatibility, and semiconductor industry standards. Stay current with evolving codes, standards, industry practices, and emerging technologies. Lead the development and maintenance of process engineering standards, master specifications, P&ID symbol libraries, templates, and documentation protocols to improve efficiency, consistency, technical quality, and speed-to-market across high-tech and semiconductor projects. Office Leadership & Culture Serve as a visible and approachable leader within the office, cultivating a positive, inclusive, and collaborative work environment where all employees feel valued, supported, and empowered to do their best work. Act as a key representative and advocate for the office's process engineering team, aligning local goals with firm-wide strategy, values, and vision. Drive staff development and career pathing for process professionals at all levels, identifying high-potential talent, and championing training, licensure, and certification opportunities. Promote a culture of continuous improvement and knowledge sharing, organizing technical forums, lunch-and-learns, and office-wide innovation challenges that leverage SSOE’s AI and digital tool ecosystem.
