From Amprius Technologies, Inc.'s posting. “We” and “our” refer to the employer.
Amprius Technologies (NYSE: AMPX) is a leader in high-energy, high-power lithium-ion batteries built on silicon anode technology. Our SiCore® and SiMaxx™ cells power unmanned aerial systems, aviation and other applications where weight and energy density matter most. Headquartered in Fremont, California, Amprius designs cells in house and produces them through a global network of contract manufacturing partners.
Summary
Amprius Technologies is hiring a hands-on Staff Electrode Process Engineer to own the electrode manufacturing process on our anode and cathode pilot line in Fremont, CA. You will own the four core electrode processes — slurry mixing, coating, calendering, and slitting — and make sure the line delivers in-spec, defect-free electrodes to the cell-assembly line on schedule and at target yield.
The role combines day-to-day process ownership (SPC, recipe and parameter optimization, defect reduction) with bringing new electrode equipment online and transferring new recipes from R&D into production. This is a highly visible role reporting to the Pilot Line Manager.
Job Responsibilities
· Own process parameters for slurry mixing, coating, calendering, and slitting on the anode and cathode lines: define and qualify process windows (slurry viscosity and solids, coating die gap and loading, calendered density and thickness, slit width and burr), and release them as specifications, recipes, and SOPs.
· Own first-pass yield and scrap for the electrode process: track yield by step and defect type, build Paretos of in-line defects (cracks, wrinkles, streaks, pinholes, loading and thickness variation, edge and burr defects), lead root-cause investigations (8D, 5-Why, fishbone), and drive corrective and preventive actions to closure.
· Implement and manage SPC on critical parameters and in-line metrology (areal loading, thickness, moisture, viscosity), and set up data collection so yield and process capability are visible by step, product, and shift.
· Design and run structured experiments (DOE) to optimize mixing, coating, calendering, and slitting parameters against yield, throughput, and electrode performance, in partnership with R&D and cell engineering.
· Make sure the line delivers assembly-ready material: own slit-roll quality, electrode drying and moisture control, roll handling and identification, and the release and handoff of electrodes to the cell-assembly line on schedule.
· Lead new-equipment and new-line implementation for the electrode process: review equipment specifications, support FAT/SAT, run test and qualification builds, and validate for production.
· Lead new product and recipe transfer from R&D to the production line, including trial runs, stabilization of initial quality, and documentation of the final process.
· Lead PFMEAs, control plans, and change control for new or changed processes; qualify changes with capability studies (Cpk, Gage R&R) before release to production.
· Write and maintain SOPs and work instructions for the four core processes; train and mentor electrode technicians and operators; support daily production troubleshooting, including occasional off-shift escalations.
· Work closely with R&D, quality, maintenance, cell assembly, and equipment vendors, and communicate process status, risks, and results clearly to technicians, peers, and leadership.
