In this role, you will focus on the development, analysis, and refinement of detailed process models that drive our technology’s integration into customer operations. Your work will span early-stage process concept development through to preliminary commercial system design, with a strong emphasis on dynamic modeling, optimization, and technical strategy. Occasional travel (~10%) is typical for all Via employees to support development and customer related activities.

Responsibilities Include :

• Develop and refine process simulation models using tools like Aspen Plus, Aspen HYSYS, ChemCAD, or equivalent
• Perform rigorous mass and energy balances, process dynamics, and optimization studies to support system development
• Translate lab-scale data and pilot system results into scalable process design.
• Collaborate in developing and updating process design documentation (PFDs, P&IDs, specifications) with process and systems engineering teams
• Conduct process sensitivity and scenario analyses to evaluate performance across operating conditions
• Assist in developing control strategies and performance specifications informed by dynamic modeling
• Support continuous improvement activities for operating facilities from a modeling and analytical perspective
