We are seeking a Jr. Process Engineer to support the development of process engineering designs for complex industrial and government (DoD/DOE) projects. This is an excellent opportunity for an early-career engineer who wants to develop strong practical process engineering skills while working alongside experienced process and chemical engineers.

The Jr. Process Engineer will support the development and maintenance of Process Flow Diagrams (PFDs), Piping and Instrumentation Diagrams (P&IDs), equipment specifications, process calculations, design documentation, and technical reports. The successful candidate will progressively take ownership of P&IDs and other process design deliverables while learning from senior and licensed engineers.

Experience or interest in Process Hazard Analysis (PHA), industrial processes, and highly regulated environments is strongly preferred. The ideal candidate is curious, detail-oriented, willing to ask questions, and motivated to develop into a well‑rounded process engineer.

• Develop, maintain, and update PFDs and P&IDs under the direction of senior process engineers.
• Progressively take ownership of assigned P&IDs, ensuring that process equipment, piping, instrumentation, controls, valves, and other design information are accurately represented.
• Assist with process calculations, equipment sizing, pressure drop calculations, material balances, energy balances, and other engineering analyses.
• Assist senior and licensed process/chemical engineers with process design activities for industrial, DOE, DoD, and other government projects.
• Review engineering drawings, specifications, equipment information, and technical documentation to develop accurate process design deliverables.
• Coordinate process engineering requirements with mechanical, structural, electrical, instrumentation and controls, civil, and other disciplines.
• Participate in design reviews and multidisciplinary coordination meetings.
• Support development of equipment and instrument specifications, datasheets, and procurement documentation.
• Assist with Process Hazard Analyses (PHA/HAZOP) and other process safety activities under the guidance of experienced engineers.
• Participate in site visits, facility walkdowns, and field verification activities to collect and document existing process information.
• Research applicable codes, standards, DOE Orders, project specifications, and other technical requirements.
• Assist with preparation of engineering calculations, reports, design criteria, technical evaluations, and other project documentation.
• Review and incorporate comments from senior engineers, project managers, clients, and other stakeholders.
• Organize and prioritize work to meet project schedules and deadlines.
• Communicate effectively, ask clarifying questions, and contribute to a collaborative team environment.
• Develop technical knowledge and engineering judgment through mentoring and hands‑on project experience.
