Scale-Up Engineer

EELI 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-scaled 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 pilot-scale systems.

As 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.

• 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 (Solid Works or similar CAD tools)
• Strong understanding of fluid systems and process hardware
• Hands-on experience building physical systems (lab, pilot, or industrial)

• Background in electrochemical systems (batteries, fuel cells, electrolysis, etc.)
• Experience with process design (PFDs, system layout, equipment sizing)
  Familiarity with pilot-scale or scale-up environments
• Exposure to instrumentation and controls (PLC, sensors, DAQ systems)

• A builder mindset — comfortable designing and assembling real systems
• Ability to work across disciplines (mechanical + process + electrochemistry)
• Strong problem-solving skills in fast-paced, evolving environments
• High ownership and willingness to take initiative

Competitive startup package including salary and equity.
