Engineering-Mechanical

Employment Type: Full-Time

Compensation: $90,000 – $110,000 USD FTE hourly, plus early-stage equity and benefits.you must thrive in a dynamic, rapidly evolving R&D environment and take strong initiative to push projects forward. We need an engineer who owns the entire design-build-test loop and can navigate ambiguity and shifting priorities. Success in this role requires being a collaborative team player who is meticulous about writing down processes, maintaining organized files, navigating ambiguity, and clearly communicating technical progress to the rest of the team. Industrial drying processes consume a significant fraction of global energy use, and high-energy gas dryers have no clear path to electrification. At Ultropia, we are creating the future by rethinking industrial drying. Instead of evaporating liquid, we use acoustic energy to mechanically extract it, moving it out of the target material without a phase change. This side-steps the thermodynamics of existing heat-based drying processes and enables hyper-efficient material processing. We are taking a laboratory-proven technology to market and want your help engineering the future of industrial drying.
