Job Title:

Project Engineer

Department:
Engineering

The Project Engineer will support the execution of commercial-scale energy projects that include Sustainable Aviation Fuel (SAF) production facility and specialty power/cooling systems. The role works cross‑functionally to ensure timely development of engineering packages and alignment between engineering, operations, procurement, and project management teams. This role is critical to maintaining technical integration, schedule discipline, and quality of engineering deliverables throughout the project lifecycle.

• Coordinate and oversee the development of engineering design packages, including process, mechanical, electrical, and instrumentation scopes.
• Serve as the primary liaison between internal engineering teams, technology providers, operations, procurement, and external vendors to ensure technical alignment and efficient workflow.
• Review and validate process and mechanical datasheets, equipment specifications, and design criteria prior to issuing documents to vendors or initiating procurement activities.
• Manage and track engineering progress, deliverable schedules, inter‑discipline reviews, and risk/issue logs.
• Manage responses to technical queries (RFIs/TQs) and ensure clear and timely communication across project stakeholders.
• Facilitate technical interface management and resolve design conflicts between engineering disciplines.
• Lead and participate in design reviews, HAZOPs, constructability reviews, and value engineering sessions.
• Support procurement activities by reviewing vendor documentation, providing technical input during bid evaluations, and ensuring vendor deliverables integrate correctly with engineering packages.
• Collaborate with the construction and commissioning teams to ensure design intent is understood and properly implemented on site.
• Ensure that all engineering activities support project goals around sustainability, safety, cost, schedule, and performance.

• Bachelor’s degree in Engineering (Mechanical, Electrical or Chemical engineering preferred).
• 3–7+ years of experience in project engineering within industrial, energy, large‑scale power projects, chemical, or renewable fuels projects.
• Experience developing or coordinating engineering design packages on large‑scale process facilities.
• Strong understanding of multidisciplinary engineering workflows (process, mechanical, E&I, civil/structural).
• Familiarity with EPC project delivery, Pre‑FEED, FEED, and detailed design workflows.
• Working knowledge of engineering document control, PFDs, P&IDs, equipment data sheets, and 3D models.
• Ability to manage multiple interfaces and coordinate processes across internal and external stakeholders.
• Excellent communication, problem‑solving, and project coordination skills.
