Position Overview

We are seeking a Senior Process Engineer to further develop and scale our PFAS Annihilator SCWO technology. The position is located in Columbus, OH. The role reports to the Chief Technology Officer.

Key Responsibilities

n
• Lead the process design and scale-up of Revive's PFAS Annihilator system, including the development and optimization of PFDs, P&IDs, process simulations, and detailed mass and energy balances to support commercial deployment.
n
• Drive continuous improvement of SCWO reactor and salt separation subsystems to enhance throughput, minimize fouling, extend service intervals, and improve overall system availability.
n
• Provide expert engineering support to field operations by resolving emergent technical challenges across the fleet; conduct root-cause analyses and implement durable corrective actions in collaboration with site teams.
n
• Specify, size, and select process equipment-including high-pressure pumps, heat exchangers, valves, blowdown systems, and instrumentation-with a focus on SCWO service conditions and corrosive fluid handling.
n
• Develop and apply thermodynamic, kinetic, and phase equilibrium models to support PFAS destruction chemistry, salt precipitation behavior, and system control strategies.
n
• Support and participate in process safety activities such as HAZOPs, risk assessments, and safety reviews for system modifications, commissioning, and new deployments.
n
• Partner with fabrication and commissioning teams to validate system designs, resolve field integration issues, and accelerate the implementation of design upgrades.
n
• Analyze operational data from commercial and demonstration units to extract performance trends, identify bottlenecks, and guide engineering decisions and future designs.
n
• Contribute to Revive's technical knowledge base by developing and documenting process improvements, system modifications, and standardized design modules for future deployments.
n

Required Qualifications
