This is a very exciting time at Enovix! We are looking for an experienced AME Assembly Engineer to support the development, installation, validation, ramp-up, and continuous improvement of assembly equipment for the company’s next-generation battery manufacturing lines. The position will work closely with AME, Process Engineering, Manufacturing, Quality, and equipment suppliers to establish stable, scalable, and high-throughput assembly operations. Job Summary: The AME Assembly Engineer will lead engineering activities for battery cell assembly equipment and processes, with a primary focus on joining technologies, assembly operations, equipment setup and validation, process optimization, and capacity improvement. The role is responsible for ensuring that new and existing assembly equipment meets safety, quality, throughput, reliability, and manufacturability requirements. The position will play a key role in improving overall equipment performance by reducing cycle time, eliminating non-value-added time, resolving chronic equipment and process issues, and supporting production ramp-up through structured engineering validation and data-driven improvement. Key Responsibilities Assembly Equipment & Process Engineering Lead engineering activities for battery assembly processes, including joining, sealing, cutting, punching, and related material-handling operations. Develop and optimize joining processes using ultrasonic welding, laser welding, resistance welding, or other applicable joining technologies. Support equipment concept review, design specification, supplier technical evaluation, and design-for-manufacturability activities. Define critical process parameters, equipment requirements, control plans, and acceptance criteria for assembly equipment. Equipment Installation, Setup & Validation Support equipment installation, commissioning, setup, debug, and production readiness activities. Plan and execute equipment qualification and validation, including FAT, SAT, IQ, OQ, PQ, capability studies, and run-at-rate testing as applicable. Verify equipment safety, functionality, repeatability, process capability, and compliance with engineering specifications. Support initial production ramp-up and stabilize equipment performance through structured issue tracking and corrective actions. Process Optimization & Capacity Improvement Analyze process performance and equipment losses to improve yield, quality, uptime, cycle time, and throughput. Maximize production capacity by identifying and eliminating waste time, bottlenecks, unnecessary motion, waiting time, and recurring equipment stops. Conduct time studies, line balancing, bottleneck analysis, and capacity modeling to improve overall line performance. Drive continuous improvement using data analysis, DOE, SPC, root cause analysis, and structured problem-solving methodologies. Equipment Reliability & Issue Resolution Lead troubleshooting of equipment, tooling, joining,…
