The electric vehicle revolution is creating an entirely new manufacturing sector in the United States. Tesla, Ford, GM, Rivian, Hyundai, BMW, and dozens of battery manufacturers are building gigafactories — massive facilities that produce battery cells, packs, and complete EV drivetrains at scale. Each gigafactory requires hundreds of automation professionals to install, program, and maintain some of the most advanced production systems ever built. For automation engineers and technicians, the EV industry represents the largest greenfield manufacturing buildout since World War II.
## What EV and Battery Automation Professionals Do
Battery manufacturing is a hybrid of chemical processing and high-speed discrete manufacturing. A lithium-ion battery cell goes through electrode coating (a continuous process using slot-die coaters), calendering (compression rollers at specific pressures), slitting, stacking or winding, electrolyte filling in dry rooms (below 1 percent relative humidity), formation cycling (controlled charge-discharge sequences that take days), and final testing.
Each step requires different automation: process control for coating and mixing, motion control for high-speed stacking, environmental monitoring for dry rooms, power electronics for formation cycling, and vision systems for quality inspection. The battery pack assembly line adds robotic welding (laser and ultrasonic), leak testing, high-voltage testing, and battery management system (BMS) programming.
## Career Levels and Compensation
**Level 1 — Manufacturing Technician ($45,000 to $62,000 / $24 to $34 per hour):** Technicians operate and maintain production equipment, perform basic PLC troubleshooting, and monitor quality. Many gigafactories offer signing bonuses and relocation packages.
**Level 2 — Automation Engineer ($68,000 to $98,000 / $38 to $56 per hour):** Engineers program PLCs and robots, design HMI screens, troubleshoot production issues, and implement continuous improvement. Battery manufacturing requires understanding both process control and discrete automation.
**Level 3 — Senior Controls Engineer ($92,000 to $135,000 / $52 to $78 per hour):** Senior engineers lead automation design for new production lines, specify equipment, manage OEM integrators, and commission multi-million dollar systems. Electrode coating and formation cycling automation is particularly well-compensated.
**Level 4 — Automation Manager ($125,000 to $175,000 / $70 to $100 per hour):** Managers lead the automation function for entire gigafactories — coordinating dozens of engineers, managing OEM relationships, and designing MES integration.
## Key Technologies
**PLC Platforms:** Allen-Bradley ControlLogix dominates North American EV plants. Siemens S7-1500 is common in European transplant factories.
**Robotics:** FANUC, ABB, and KUKA robots perform welding, material handling, and inspection. Collaborative robots handle flexible assembly tasks.
**Vision Systems:** Cognex, Keyence, and SICK vision systems inspect electrode coating quality and detect defects. Machine learning-based inspection is increasingly common.
**MES and Traceability:** Every battery cell must be traceable from raw material to vehicle — making MES integration a critical skill.
**Dry Room Controls:** Maintaining humidity below 1 percent in rooms the size of football fields requires sophisticated HVAC automation.
## Where the Jobs Are
**Southeast:** Ford BlueOval City (Tennessee), SK Innovation (Georgia), Hyundai (Georgia), BMW (South Carolina).
**Midwest:** GM Ultium Cells (Ohio and Michigan), Stellantis/Samsung SDI (Indiana), Ford (Michigan).
**Southwest:** Tesla Gigafactory Texas, Tesla Gigafactory Nevada, Panasonic (Kansas).
## Getting Started
EV manufacturing is actively hiring from adjacent industries. Automotive, food and beverage, pharmaceutical, and general manufacturing automation experience all transfer well. If you have three to five years of PLC and robotics experience, you are a strong candidate for EV automation roles.
