Senior Process Engineer and Office Leader

About the role

Imagine engineering the sophisticated fluid, gas, and chemical delivery systems that form the lifeblood of the world's most advanced semiconductor fabrication facilities and leading the team that makes it happen. At SSOE, you won't just be executing tasks; you'll continuously expand your expertise by confronting diverse and complex process engineering challenges unique to the semiconductor and advanced high-tech industrial sectors, while simultaneously guiding the culture, growth, and operational excellence of your office.

Responsibilities

• 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.
• 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.

Qualifications

• Bachelor’s degree in Chemical Engineering from an accredited program.
• Professional Engineer (PE) license is preferred; active PE license in good standing within the U.S. with ability to obtain reciprocity as needed is highly valued.
• 10+ years of process engineering experience, with a strong and demonstrated focus on semiconductors, advanced high-tech industrial, cleanroom, or similarly complex process utility design.
• Proven leadership in managing and guiding internal process engineering design teams through all project phases within a design-build delivery model.
• Demonstrated experience in office leadership, people management, or team development.
• Excellent communication, presentation, and client-facing skills, with the ability to clearly articulate complex process engineering concepts, P&IDs, and risk assessments to diverse audiences including engineers, EHS managers, project managers, contractors, client technical leadership, and community stakeholders.
• A proven track record of building and sustaining client relationships, contributing to business development, and participating in proposal development and interviews within the semiconductor and high-tech manufacturing industry.
• Demonstrated experience fostering an inclusive team culture and a commitment to mentoring and developing technical professionals.
• Experience with projects that demonstrate thoughtful, code-compliant, and technically precise process system designs for semiconductor, high-tech, or comparable mission-critical facilities.

Preferred Qualifications

• Direct experience with semiconductor wafer fabrication facility process system design across multiple technology nodes.
• Experience with bulk gas tank farm design and knowledge of hydrogen gas safety and distribution per CGA and NFPA 55.
• Experience with solvent and acid waste segregation, collection, and treatment design, including knowledge of explosion-proof and fire-rated enclosure requirements for solvent piping systems.
• Knowledge of sustainable process design practices, including UPW reclaim/recycle strategies, waste heat recovery, and chemical minimization initiatives, and familiarity with LEED or equivalent green building frameworks.
• Experience leading organizational change, implementing new technologies (including AI) into process design workflows, and driving a culture of innovation.

Compensation & Benefits

• Salary: $130,000 – $200,000 per year, commensurate with location, education, and depth of experience.
• Incentives: Leadership bonus program and ownership investment opportunities.
• Health & Wellness: Comprehensive medical, dental, and vision insurance; employer-paid life insurance; and wellness program support.
• Retirement: 401(k) plan with company match.
• Professional Growth: Dedicated professional development funding, PE licensure and certification exam support, conference attendance, and structured career advancement programs.
• Time Off: Generous paid time off (PTO) policy plus paid holidays.
• Work-Life Balance: SSOE actively supports flexible scheduling within project commitments and a culture that genuinely respects your time outside the office.
