Mechanical Engineer - Intern or Co-op at Revive Environmental Technology, LLC

Job DescriptionJob DescriptionAbout Revive Environmental TechnologyRevive 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 OverviewWe are seeking a Mechanical 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: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 QualificationsKnowledge and/or experience in process engineering design.Strong safety record and mindset.Experience with CAD modelingExcellent problem-solving and cross-disciplinary collaboration skills.GPA of a 3.0 or betterPreferred QualificationsPrior coursework with a "B" or better grade in Thermodynamics and FluidsExperience / prior exposure to sensor and actuator selection and integrationIndustrial 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 ReviveContribute 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.
