Principal Engineer

ION Storage Systems offers solid‑state battery solutions that prioritize performance, safety, and durability. The company focuses on a variety of portable and stationary energy storage applications, leveraging a patented, three‑dimensional ceramic design that provides a sustainable approach to next‑generation energy storage. Built on a scalable, modular ceramic structure, ION's batteries are ready to meet the demands of an increasingly electrified world.

As part of the Cell Engineering group, you will use your experience, leadership, and technical creativity to develop and optimize a 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 will work on equipment and processes as we refine them toward volume production and new commercial products. You will collaborate with cell, mechanical, equipment, and automation engineers and technicians to drive improvements for process speed, yield, and reliability.

• Work collaboratively with the team to support the existing prototype line, identifying key levers to drive optimal process reliability, quality, and uptime.
• Lead root‑cause investigations for difficult or ambiguous equipment and process failures, driving corrective/preventive actions to closure.
• Own the design, build, and commissioning of new equipment and fixtures from concept through installation, working across mechanical, electrical, and controls disciplines.
• Translate process requirements into robust hardware and automation specifications.
• Mentor and provide technical guidance to other engineers and technicians on the team; review designs and troubleshooting approaches.
• Partner with process/cell engineers to understand upstream process needs and downstream implications of equipment design choices.
• Contribute to engineering standards and documentation practices appropriate for a scaling organization.
• Independently manage priorities across multiple ongoing projects with minimal oversight.

• Strong foundation of hands‑on experience as an engineer.
• Experience building first‑of‑its‑kind hardware and software for automated systems.
• Strong mechanical design fundamentals. Experience in 3D CAD for design of equipment, tooling, fixtures, and assembly aids.
• B.Eng., M.Eng.,
  
  B.Sc., M.Sc. in Mechanical Engineering, Electrical/Controls Engineering, Mechatronics or a related discipline.
• 10+ years of work experience (post‑B.S.).

• Experience in cell assembly, semiconductor, or related field.
• Experience standing up a pilot or prototype line from an early stage.
• Experience working directly with equipment vendors on custom or first‑of‑a‑kind tooling.

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. Ability to stand, bend, and move around equipment and lab benches for extended periods.
