Process Engineer – Intern or Co-op

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 Process Engineer Intern or Co-Op to further develop and scale our PFAS Annihilator SCWO technology. The position is based in Columbus, OH. The role reports to the Chief Technology Officer. How an internship or Co-Op would be different with Revive than other companies is we give real world challenges to solve to each team member, interns and Co-Ops included. Your work would be on a project that has meaningful contribution to Revive as a growing young company, and the learning opportunities are fast paced and mission critical.

Key Responsibilities for your projects could be:

• Lead the process design and scale-up of Revive's PFAS Annihilator system. This could include development and optimization of PFDs, P&IDs, process simulations, and performing mass and energy balances, etc.
• Drive continuous improvement of SCWO reactor and salt separation subsystems to enhance throughput, minimize fouling, extend service intervals, and improve overall system availability.
• Provide 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.
• 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

• Prior coursework with a "B" or better in Mass, Heat, and Energy balance and Separation technology.
• Knowledge and/or experience in process engineering design.
• Strong safety record and mindset.
• Excellent problem-solving and cross-disciplinary collaboration skills.
• GPA of a 3.0 or better

Preferred Qualifications

• Prior coursework with a "B" or better grade in Thermodynamics and Kinetics
• Industrial experience.
• Familiarity with PFAS chemistry.
• Background in thermal reaction systems, heat integration, and fluid mechanics.
• Experience with fabrication, manufacturing, and good lab practices.

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.
