EELI Technology is building the future of lithium production. As a venture-backed company, EELI 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. What you’ll do:- Lead the design and development of electrochemical reactor systems, including flow cells, modules, and supporting hardware.- Perform mechanical design using CAD (SolidWorks) for reactors, enclosures, manifolds, and system layouts.- Develop process flow concepts, including fluid handling, pumping, and system integration.- Size and specify tanks, tubing, pumps, valves, and instrumentation for lab and pilot systems.- Build and assemble prototype and pilot-scale systems, working directly in the lab.- Collaborate with electrochemists to translate experimental requirements into engineered systems.- Support scale-up efforts from lab to pilot, including system debugging and iteration.- Work with vendors and fabricators to source and manufacture components.- Document designs, system configurations, and test results. Qualifications:- BS or MS in Chemical Engineering, Mechanical Engineering, or related field- 2+ years of relevant industry or applied research experience (flexible for exceptional candidates)- Experience with mechanical design (SolidWorks or similar CAD tools)- Strong understanding of fluid systems and process hardware- Hands-on experience building physical systems (lab, pilot, or industrial) Job type: Full-time, on-siteExperience: 2–7 yrs (ChemE/MechE)Apply by emailing your resume to contact@eeli.tech
