As part of our Cell Engineering group, you'll use your background in mechanical engineering and technical creativity towards the development and optimization of first-of-its-kind prototyping line for ION's solid state cells and anodes. Because this is a prototype line rather than a mature production system, you'll be working on equipment and processes as we refine them toward volume production and new commercial products. You'll collaborate with cell engineers, other automation engineers and technicians to drive improvements for process speed, yield, and reliability.

Responsibilities

  • Design, build, and iterate on mechanical equipment, tooling, and fixtures to support prototype cell fabrication
  • Troubleshoot equipment and process issues on the line, working hands-on to identify root causes and implement fixes
  • Support installation, setup, and debugging of new equipment
  • Measure and evaluate the performance of designs and process changes against yield, speed, and reliability targets
  • Collaborate with cell engineers and technicians to translate process requirements into mechanical solutions
  • Maintain detailed documentation for all phases of work

Experience and Qualifications

  • B.S. or M.S. in Mechanical Engineering or related field
  • 0-3 years of work experience (post B.S.)
  • Experience in 3D CAD for design of equipment / tooling / fixtures / assembly aids
  • Experience in measurement of outcomes of your designs
  • A passion for creative problem solving

Preferred

  • Machining experience (manual or CNC mill/lathe) sufficient to fabricate and modify prototype parts, tooling, and fixtures to specified tolerances
  • Experience with GD&T and precision fit/tolerance analysis
  • Exposure to automation controls (PLCs, sensors, actuators) or willingness to learn

Physical Demands and Working Conditions

  • Work onsite at ION's Beltsville, MD facility; this is a hands-on and collaborative role requiring regular presence
  • Wear personal protective equipment including, but not limited to, a lab coat, gloves, safety glasses, and safety-toe shoes.
  • Pass a respirator fit test and be able to wear respiratory protection on a periodic basis
  • Ability to stand, bend, and move around equipment and lab benches for extended periods

Benefits

In addition to a competitive salary and equity incentives, we offer the following company benefits:

  • Medical, dental, vision, disability, and life insurance
  • Equity opportunities in the company
  • Company and floating holidays
  • 17 days of PTO to start, with increase upon tenure

What They Do

Ion Storage Systems specializes in the development and manufacturing of next-generation solid-state lithium-metal batteries, leveraging a patented three-dimensional ceramic architecture that replaces conventional liquid-electrolyte lithium-ion designs (source: maryland.gov, ionstoragesystems.com). Their technology targets a broad range of markets including defense and aerospace, consumer electronics, electrified transportation, medical devices, and grid or stationary storage applications (source: linkedin.com, ionstoragesystems.com). Ion’s batteries are designed to be safer, lighter, and capable of supporting tighter packing densities, making them especially suitable for compact, high-performance devices such as military wearables, portable electronics, and electric vehicles (source: linkedin.com). The company’s platform is built on a scalable, modular, three-dimensional ceramic structure and includes a first-of-its-kind prototyping line for solid-state cells and anodes, emphasizing safety, durability, and form-factor flexibility (source: ionstoragesystems.com).

Projects & Track Record

Ion Storage Systems has progressed from a university spinoff to pilot-scale manufacturing and early commercialization. Its Beltsville pilot production line, known as "Megapede," has a capacity of 1 MWh per year with plans to scale up to 10 MWh annually (source: manufacturingdive.com). The company produced its first multi-layer ceramic solid-state battery cell on a semi-automated production line in March 2025 at its Beltsville facility (source: ionstoragesystems.com). In August 2025, Ion launched "Cornerstone," its first commercial generation of solid-state battery technology, which began shipping to leading consumer electronics companies (source: umd.edu). The company is also collaborating with the U.S. Army to domestically produce conformal wearable batteries for field electronics such as radios, with the pilot line expected to produce 100,000 military batteries annually (source: manufacturingdive.com, maryland.gov).
