Scale-Up Engineer (Electrochemical Systems)

Company DescriptionEELI Technology is developing next-generation electrochemical systems to enable sustainable lithium recovery from low-grade resources. Our platform integrates electrochemistry, fluid systems, and modular reactor design to unlock new pathways for domestic critical mineral production.We are seeking a Scale-Up Engineer to help bridge the gap between lab-scale innovation and real-world deployment. This role sits at the intersection of mechanical design, process engineering, and system integration, and will play a critical role in building EELI's first pilot-scale systems.Role DescriptionAs a Scale-Up Engineer, you will design, build, and iterate on electrochemical reactor systems and supporting process infrastructure. You will work closely with the founding team to translate experimental insights into functional, scalable hardware.This is a hands-on, build-first role requiring both engineering design and practical execution.QualificationsBS or MS in Chemical Engineering, Mechanical Engineering, or related field2+ years of relevant industry or applied research experience (flexible for exceptional candidates)Core RequirementsExperience with mechanical design (SolidWorks or similar CAD tools)Strong understanding of fluid systems and process hardwareHands-on experience building physical systems (lab, pilot, or industrial)PreferredBackground in electrochemical systems (batteries, fuel cells, electrolysis, etc.)Experience with process design (PFDs, system layout, equipment sizing)Familiarity with pilot-scale or scale-up environmentsExposure to instrumentation and controls (PLC, sensors, DAQ systems)What We're Looking ForA builder mindset — comfortable designing and assembling real systemsAbility to work across disciplines (mechanical + process + electrochemistry)Strong problem-solving skills in fast-paced, evolving environmentsHigh ownership and willingness to take initiativeCompensationCompetitive startup package including salary and equity.
