About Revive Environmental Technology

Revive Environmental Technology, LLC ("Revive") is a mission-driven environmental technology company focused on delivering rapid, permanent solutions for PFAS and other persistent environmental contaminants. Our flagship PFAS Annihilator® systems are built on patented supercritical water oxidation (SCWO) technology and are setting a new standard in liquid waste destruction, including PFAS-laden AFFF concentrates and complex organic waste streams.

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

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.

Drive continuous improvement of SCWO reactor and salt separation subsystems to enhance throughput, minimize fouling, extend service intervals, and improve overall system availability.

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.

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.

Develop and apply thermodynamic, kinetic, and phase equilibrium models to support PFAS destruction chemistry, salt precipitation behavior, and system control strategies.

Support and participate in process safety activities such as HAZOPs, risk assessments, and safety reviews for system modifications, commissioning, and new deployments.

Partner with fabrication and commissioning teams to validate system designs, resolve field integration issues, and accelerate the implementation of design upgrades.

Analyze operational data from commercial and demonstration units to extract performance trends, identify bottlenecks, and guide engineering decisions and future designs.

Contribute to Revive's technical knowledge base by developing and documenting process improvements, system modifications, and standardized design modules for future deployments.

Required Qualifications

10+ (preferably 15+) years' experience in process engineering design, preferably in high-pressure, high-temperature, or hazardous waste treatment systems.

Strong safety record.

Strong background in thermal reaction systems, heat integration, and fluid mechanics.

Excellent problem-solving and cross-disciplinary collaboration skills.

Preferred Qualifications

Experience with SCWO, wet air oxidation, or hydrothermal processing.

Familiarity with PFAS chemistry, AFFF treatment, or salt-laden wastewater.

Experience with modular skid-based systems and field deployment of process equipment.

Experience with fabrication, manufacturing, and good lab practices.

Experience working with small teams and/or in technology scaling and optimization.

Why Join Revive

Contribute directly to solving one of the most pressing environmental challenges of our time.

Work alongside an agile, mission-driven team combining deep science with practical field engineering.

Be at the center of scaling up one of the first proven PFAS destruction systems to national and international markets.

Competitive compensation and growth opportunities in a fast-scaling cleantech company.
