Job description
Ion Storage Systems is scaling its solid-state battery manufacturing from a low-throughput prototype line to a high-volume automated production line - a >100x increase in throughput. We're looking for a Director of Manufacturing Engineering to lead this transformation, with the primary mandate being equipment and automation: designing, specifying, and integrating the automated systems that will carry us from prototype to high-volume production. Process engineering support is part of the role, but the center of gravity is machine design, controls, robotics, and line architecture - not process/yield work.
This is not a role for someone who only optimizes an existing process, or who has only ever integrated a single automation cell in isolation. We need a leader who has designed and built the automated equipment and line architecture behind a major scale-up before - from pilot volumes to high-volume, automated production - ideally in battery, semiconductor, MEMS, or another precision manufacturing environment.
What You'll Do
- Own the equipment and automation roadmap to take our prototype line to >100x throughput: line architecture, automated material handling, robotics, in-line metrology/inspection, and process control systems.
- Lead line design and layout from an equipment-first perspective - bottleneck/constraint analysis, line balancing, and capacity modeling driven by machine and station design.
- Direct the design, specification, and build/integration of automation systems, partnering closely with equipment vendors and integrators, and building custom equipment in-house where it makes sense.
- Own capital equipment planning: build-vs-buy decisions, vendor selection, equipment budgets, and project timelines
- Establish the controls, in-line inspection, and equipment-level metrics needed to run a high-volume automated line reliably and continuously (OEE, uptime, in-line inspection, traceability).
- Build and lead a team weighted toward automation, controls, and equipment engineers, with process engineering support embedded.
- Partner with cell and metrology engineers to ensure equipment designs accommodate cell process requirements
What You Bring
- 10+ years in automation/equipment/manufacturing engineering, with at least one prior experience designing and building the automated equipment behind a major scale-up (pilot/prototype → high-volume automated production) - this is the single most important qualifier.
- Deep, hands-on experience in automation and equipment engineering: machine design, robotics, controls (PLC/motion/vision systems), in-line metrology/inspection, and line integration.
- Experience leading and successfully executing multiple projects in parallel, through all phases of design, from early concept through validation and handoff.
- Demonstrated excellence at building and leading teams. Experience managing team members to emphasize their strengths and support their professional development.
- Strong systems-level thinking: comfortable with capacity/throughput modeling, constraint analysis, and translating that into a concrete roadmap.
- B.Eng. M.Eng, B.Sc. M.Sc. in Mechanical, Electrical/Controls, Chemical, or Materials Engineering, Mechatronics, or a related discipline.
Preferred
Background in battery, semiconductor, MEMS, or another precision, high-throughput manufacturing industry strongly preferred
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
- Hybrid - in-person preferred at our Beltsville, MD headquarters
- Company and floating holidays
- 17 days of PTO to start, with increase upon tenure
- 401k plan with a 4% company match beginning after first paycheck
- Wellness allowance of $1k annually
Salary Range: $170k to $250k

Founded2019
SizeApproximately 150 employees in recent years (source: linkedin.com, manufacturingdive.com)
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).
