Jupiter Volta is developing a novel carbon plasma chemistry process based on its innovative plasma system, and seeks a Senior Process Engineer to take technical ownership of our reactor performance, tool uptime, and data pipelines. This role will work hands-on with our plasma systems, defining and leading experimental campaigns, establishing operating windows, driving root-cause analysis on complex equipment issues, and spearheading reactor characterization as we scale toward commercial throughput. This is a role for an experienced engineer who thrives on the floor and in the lab, working autonomously and alongside cross-functional leadership to turn operational data into scalable engineering solutions.
