Job DescriptionJob DescriptionAbout 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 Mechanical Engineer 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 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 company, and the learning opportunities are fast paced and mission critical.

Key Responsibilities for your projects could be:

Engineering Design & System Development

• Design, prototype, and iterate mechanical components and subsystems for Annihilator systems and support equipment.
• Assist in the selection and specification of mechanical equipment including pumps, valves, fittings, and materials for high-temperature/high-pressure environments.
• Support assembly, fit-up, and testing of newly fabricated equipment; identify and resolve mechanical interferences and installation issues.

Operations Support and Troubleshooting

• Collaborate closely with site operators, technicians, and engineers to support day-to-day operations of the SCWO systems.
• Investigate and resolve mechanical failures or equipment anomalies, conducting root cause analyses and implementing corrective actions.
• Develop and implement maintenance procedures, equipment setup guides, and operating protocols for mechanical systems.

R&D and Process Optimization

• Collaborate with chemical/process engineers to translate theoretical concepts into testable mechanical solutions (e.g., injection hardware, quench systems, thermal shielding, brine handling).
• Analyze test results, identify trends, and recommend mechanical or operational changes to increase system uptime, throughput, or maintainability.
• Assist in designing and executing long-duration reliability tests to characterize mechanical component performance over time under SCWO-relevant conditions.

Required Qualifications

• Knowledge and/or experience in process engineering design.
• Strong safety record and mindset.
• Experience with CAD modeling
• Excellent problem-solving and cross-disciplinary collaboration skills.
• GPA of a 3.0 or better

Qualifications

• Prior coursework with a "B" or better grade in Thermodynamics and Fluids
• Experience / prior exposure to sensor and actuator selection and integration
• 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 and international markets.
• Competitive compensation and growth opportunities in a fast-scaling cleantech company.
