About Revive Environmental

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

Position Overview

Revive is seeking a highly capable and hands-on Mechanical R&D Engineer. This hybrid role combines bridges engineering with technology development. The ideal candidate will participate in engineering design, operations, and R&D activities.

The position full time, salaried, and located in Columbus, OH.

Key Responsibilities

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.
• Contribute to mechanical design reviews and ensure manufacturability, serviceability, and integration with electrical and controls subsystems.
• 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.
• Assist in test planning, commissioning, and dry runs of new systems or modifications.

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.
• Contribute to the development of scalable mechanical solutions for brine handling, salt separation, and high-temperature effluent flow control.
• Assist in designing and executing long-duration reliability tests to characterize mechanical component performance over time under SCWO-relevant conditions.
• Participate in patent disclosures or technical write-ups related to novel mechanical innovations emerging from R&D activities.

Documentation & Communication

• Maintain detailed records of system configurations, test conditions, design iterations, and field modifications.
• Collaborate with the engineering team to update drawings, schematics, and SOPs following successful implementations or fixes.
• Present findings and recommendations from troubleshooting and tests to cross-functional teams and senior leadership.

Required Qualifications

• 10+ years experience in engineering and/or R&D, preferably in small, fast-moving, dynamic environments.
• Strong safety record.
• Hands-on mechanical design, test rig setup, and system troubleshooting.
• Willingness to work in a laboratory and industrial environment, including exposure to chemicals and mechanical systems.
• Excellent problem-solving and cross-disciplinary collaboration skills.
• Strong communication and documentation skills.
• A proactive, entrepreneurial mindset with an eye for operational excellence.

Preferred Qualifications

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