Battery Technician

Location: Seattle, WA

Type: Full-time (or part-time), on-site

Overview

Ecellix is seeking a Battery Technician with at least 2 years of hands-on experience making and testing electrochemical cells. This person will be responsible for building cells, running test protocols, maintaining cell-building equipment and workflows, and generating high-quality, reproducible data. This is a hands‑on role for someone who already understands the discipline required for battery lab work.

Key Responsibilities

• Fabricate lithium-ion test cells, including coin cells, pouch cells, and other formats as needed
• Prepare electrodes through slurry mixing, coating, drying, punching, pressing, calendering, and related steps
• Assemble cells in glovebox or dry-room environments
• Run electrochemical test protocols including formation, cycling, rate testing, and other standard evaluations
• Maintain accurate records of build parameters, material lots, test conditions, and results
• Identify and troubleshoot common cell‑build and test issues
• Maintain and help qualify lab equipment such as mixers, coaters, balances, crimpers, cyclers, and gloveboxes
• Work closely with materials and process teams to evaluate new anodes, formulations, and cell designs
• Support SOP development and continuous improvement of battery workflows
• Follow strict safety and contamination‑control practices

Qualifications

• BS in materials science, chemistry, chemical engineering, mechanical engineering, or related field
• 2+ years of hands‑on experience making and testing battery cells
• Direct experience with electrode fabrication and electrochemical cell assembly
• Experience with battery cyclers and routine electrochemical testing
• Strong recordkeeping and data discipline
• Ability to work independently in a fast‑paced lab environment

Preferred Skills

• Experience with silicon anodes or other high‑expansion anode materials
• Experience with slurry formulation, coating development, or calendering
• Experience with pouch cells in addition to coin cells
• Familiarity with failure analysis and troubleshooting of cell performance issues
• Experience in startup or pilot‑line environments

What Success Looks Like

• Builds cells reproducibly with low error rates
• Generates trustworthy electrochemical data
• Flags problems early and troubleshoots systematically
• Helps establish robust battery workflows as Ecellix scales
