Facilities Process Systems Engineer (Industrial Infrastructure)

We are seeking a Facilities Process Systems Engineer to join our infrastructure engineering team. You will be responsible for the design, integration, and operational support of complex process systems that serve the “heart” of our industrial facilities. This role is focused on high-purity fluid and gas delivery, specialized wastewater treatment, and the infrastructure retrofits required to support large-scale manufacturing operations. This is a dynamic, “cradle-to-grave” engineering role. You will work directly with stakeholders to establish design requirements, produce construction documentation, and provide technical oversight during the integration and construction phase. If you have a passion for designing the systems that keep complex facilities operational, this role offers the challenge of working on some of the most densely engineered environments in the industry., Design & Engineering Delivery Systems Design: Lead the design and layout of wet/dry piping, process mechanical systems, high-purity water systems, chemical distribution, and specialty gases. Infrastructure Integration: Perform engineering calculations, component sizing, and equipment specification to retrofit existing building systems for new process requirements. Construction Documentation: Produce detailed construction documents (plans, P&IDs, schedules, and technical specs) that ensure seamless installation and system integration.

Collaboration & Stakeholder Oversight Technical Interface: Partner with cross-functional design teams, equipment owners, and vendors to build utility requirement documentation for complex manufacturing tools. Construction Support: Interact directly with clients and contractors throughout the project lifecycle. Assist with RFI responses, submittal reviews, and onsite construction support to ensure the design intent is realized. Project Lifecycle: Work within a fast-paced environment to establish design criteria, evaluate engineered systems, and recommend technical solutions that meet project constraints.

Education: Bachelor’s degree in Chemical or Mechanical Engineering from an ABET-accredited university. Experience Baseline: Minimum of three (3) years of practical application in chemical/mechanical facilities engineering (e.g., ultrapure water, chemical/gas distribution, process piping, exhaust, or waste drain systems). Delivery Experience: Demonstrated experience in the full design project delivery lifecycle. Technical Proficiency: Proven ability to collaborate in multi-disciplinary teams and effectively communicate technical requirements.

Preferred Attributes Design Tools: Proficiency in AutoCAD and/or BIM software. Field Credibility: At least three (3) years of field-level experience; you should be as comfortable in a construction trailer as you are in the design office. Certification: EIT (Engineer-in-Training) or PE (Professional Engineer) license is highly desired. Analytical Aptitude: Strong problem-solving skills with a “forward-thinking” mindset-someone eager to learn best practices and contribute innovative design solutions.
