Battery Cell Engineer Jobs in Washington (NOW HIRING)

As part of our Cell Engineering group, you will leverage deep knowledge of electrochemistry towards advancing the development and testing of ION's solid-state cells from our first-of-its-kind prototype line. As a Senior Cell Engineer, you will independently design and lead experiments that connect process or component-level changes to cell outcomes, and apply rigorous statistical methods to investigate root causes of performance variation. You will partner closely with automation engineers, metrology engineers, and technicians to drive improvements in the prototype line and ensure critical to quality metrics are met.This is a hands-on technical role for someone with electrochemical expertise, strong experimental rigor, and a collaborative approach to problem-solving. Because this is a prototype line rather than a mature production system, you'll help define and refine processes as we scale toward volume production and new commercial products.Responsibilities:Independently design and lead experiments to optimize ION's solid-state cells, anodes, and assembly processesInvestigate root causes of performance variation or failures using rigorous analytical and statistical methods, connecting findings to actionable design or process changesDefine and execute on validation plans for new materials, components, and process changesMaintain clear documentation and process tracking. Communicate specific gaps in prototype line build tracking and monitoring for continuous improvement.Contribute to current hiring with the growth of the team. Mentor junior cell engineers on experimental design, analysis techniques, and lab best practices.Follow safety guidelines for handling and ensuring proper disposal of cells and chemicalsComplete hands-on training on the prototype line, to understand its operation at a deep levelExperience and Qualifications:B.S. or Masters degree in Chemistry, Chemical Engineering, Materials Science, or related field with 4+ years of relevant industry or research experience or Ph.D. with relevant industry or research experienceStrong foundation in electrochemistry, electrochemical systems, and battery test methodsDemonstrated experience independently leading experiments or projects from design through completionStrong "soft skills" including: Strong attention to detail, excellent technical communication and organizational skills, and ability to mentor and collaborate effectively across disciplinesA passion for creative problem solving in a fast-paced prototype environmentPreferred:Proficiency in Python or similar tools for data analysis and visualization; or comfortable using A.I. tools to develop code for automated data analysisExperience with failure prediction and investigation methods, such as Root Cause Analysis and Failure Modes and Effects Analysis Physical Demands and Working Conditions:Work onsite at ION's Beltsville, MD facility; this is a hands-on and collaborative role requiring regular presenceWear personal protective equipment including, but not limited to, a lab coat, gloves, safety glasses, and safety-toe shoesPass a respirator fit test and be able to wear respiratory protection on a periodic basisAbility to stand, bend, and move around equipment and lab benches for extended periods Benefits:In addition to base salary and equity, we offer the following company benefits:Medical, dental, vision, disability, and life insuranceStock options in an early-stage companyCompany and floating holidays17 days of PTO to start, with increase upon tenure401(k) plan with a 4% company match beginning after first paycheckWellness allowance of $1,000 annuallyCompany DescriptionION Storage Systems is commercializing breakthrough solid-state lithium metal battery technology, based on discoveries made at the University of Maryland, that prioritizes performance, safety, and durability.
