Manufacturing Engineer BESS Module EOL Testers

Centillion Infotech LLC•Lower Saucon Township, PA

12d•$38 - $40•Onsite

About The Position

We are seeking a Manufacturing Engineer with strong electrical and mechanical expertise to design, develop, and deploy automated End-of-Line (EOL) testing systems for Battery Energy Storage System (BESS) modules. The ideal candidate will have hands-on experience with high-voltage battery modules, automated test fixtures, BMS validation, and manufacturing process optimization in EV or battery manufacturing environments.

Requirements

Bachelor's degree in Mechatronics, Electrical, Mechanical, or Production Engineering.
4+ years of experience working with high-voltage battery modules or power electronics.
2+ years of experience in EV/BESS battery module assembly, automated test fixtures, or EOL testing.
Strong knowledge of 4-wire Kelvin resistance measurements.
Hands-on experience with CAN, CANalyzer, CAN FD, I2C, and MODBUS communication.
Proficiency in SolidWorks or Inventor and AutoCAD Electrical or EPLAN.
Experience with DMMs, ACIR/DCIR testing, and battery validation equipment.
Knowledge of lithium-ion battery safety procedures and manufacturing quality standards.
Strong troubleshooting skills in electrical, mechanical, and automation systems.

Responsibilities

Design and develop automated EOL test fixtures for BESS battery modules.
Create mechanical fixtures using pneumatic/mechanical actuation, pogo pins, and blind-mate connectors.
Develop electrical schematics for low-voltage sensing and medium-voltage charging/discharging circuits (48V–150V DC).
Integrate test equipment including DMMs, ACIR/DCIR testers, thermal cameras, smoke detectors, and isolation monitoring devices.
Program and validate BMS communication using CAN, CAN FD, I2C, and MODBUS protocols.
Perform Gauge R&R studies to ensure accurate and repeatable test measurements.
Implement barcode-based traceability for module testing and manufacturing data.
Ensure compliance with UN 38.3, UL 1973, and IEC 62619 battery safety standards.
Optimize production test cycle times through automation and parallel testing strategies.
Troubleshoot electromechanical failures and identify manufacturing or test equipment issues.
