Associate Process Engineer

Jupiter Volta is scaling the RF plasma-based nitrogen fixation process toward industrial nitric acid production, and we need someone to help keep the tools running and the data flowing. This role will work hands-on with our plasma reactor systems day-to-day — supporting experimental runs, monitoring process parameters, troubleshooting equipment issues, and helping characterize reactor performance as we push toward production-scale throughput. This is a role for someone who's energized by being in the lab or on the floor as much as at a desk, working closely with our process engineering lead to keep experiments moving and turn operational data into insight. Key Responsibilities: Design, run, and troubleshoot (process type, e.g., chemical/plasma/thermal) experiments to characterize (key outputs — yield, efficiency, purity, throughput) Own process instrumentation and diagnostics including, but not limited to, gas analyzers, spectrometers, mass spec, OES Develop and maintain process models (mass/energy balances, kinetics, equipment sizing) using Python and/or JMP Work cross-functionally with mechanical/electrical/software teams, leadership to integrate process requirements into system design Analyze historian/SCADA data to monitor process health and identify optimization opportunities Maintain safety protocols for handling hazardous materials — reactive gases, corrosives, high pressure Document experimental procedures, results, and process specifications Required Skills and Experience: 1+ years of experience in process/chemical engineering B.S./M.S. in Chemical Engineering, Chemistry or related field Working knowledge of reaction engineering / thermodynamics / mass transfer / fluid dynamics Comfort with data analysis and scripting (Python, SQL, or similar) Experience working in a lab or pilot-plant environment with hazardous materials Strong written communication for documenting process specs and findings Bonus Skills: Experience with plasma tools Familiarity with PLC/SCADA systems Startup or fast-paced R&D experience where you wear multiple hats Jupiter Volta is an early-stage startup. Compensation will include equity and be awarded based on experience.
