Perform spot welding, tab welding, and interconnect assembly using Amada and Hesse welding machines while ensuring precision and safety.
Inspect and test battery cells, modules, and packs for quality compliance, including voltage, resistance, and thermal checks.
Diagnose and troubleshoot issues during assembly and testing, working closely with engineering teams to resolve problems.
Document test results, production data, and any non-conformities in accordance with quality standards.
Follow ESD, safety, and cleanroom protocols when handling sensitive battery components.
Support preventive maintenance and calibration of Arbin cyclers, welding equipment, and other production tools.
Collaborate with manufacturing engineers to improve production efficiency and implement process improvements.
Assist in training new technicians on battery testing, welding, and assembly processes.

Qualifications and Skills:

Associate degree or technical certification in aerospace, mechatronics, electronics, or related field (associate degree preferred).
1–3 years of experience in battery pack assembly, testing, or manufacturing environment.
