About The Position

At Archer, we’re scaling production of our High Voltage Electric Propulsion System — the heart of our eVTOL aircraft, which includes the High Voltage Battery, Electric Motor and Propeller assemblies and represents one of the most technically demanding, highly automated manufacturing systems in our factory.

Requirements

Bachelor’s degree in Electrical, Mechanical, Manufacturing Engineering, or equivalent
3+ years of manufacturing test engineering experience; EV battery or electric motor production strongly preferred
Hands-on experience with production test equipment and automated electrical test systems
Strong understanding of high-voltage safety, battery and motor manufacturing processes
Experience with battery testing (capacity, IR, balancing, BMS configuration) and motor testing (back-EMF, insulation, ESS, dyno, torque/speed characterization)
Proficiency in test data analysis, SPC, and manufacturing test data systems (MES)
Experience bringing production test equipment from prototype through mass production
Strong troubleshooting skills across test equipment, product, and process issues
Comfortable working on the production floor with technicians and operators
Ability to create, validate, and sustain manufacturing test procedures and work instructions
Solid communication skills and experience working cross-functionally

Nice To Haves

Direct experience in battery module/pack and/or electric motor manufacturing
Familiarity with battery and motor production processes (welding, winding, balancing, automated assembly)
Experience with BMS or motor controller programming and EOL configuration
Knowledge of industrial communications (CAN, Ethernet/IP, Modbus) and PLC-based automation
Experience with dynamometer testing, power electronics, or motor control
Exposure to aerospace manufacturing, AS9100, or eVTOL programs
Experience with lean manufacturing and production ramp-ups
Ability to support multiple shifts during critical production phases

Responsibilities

Lead End-of-Line (EOL) and in-process test development for High Voltage batteries and electric motors, covering performance, safety, and system integration
Design and deploy manufacturing test strategies including hipot, insulation resistance, winding verification, electromagnetic performance, and ESS
Specify, validate, and commission production test equipment, including installation, FAT, and production readiness
Program, maintain, and optimize automated test equipment (ATE), test sequences, pass/fail logic, and data collection systems
Partner with Manufacturing, Design, Quality, and Test teams to integrate test stations into production lines and improve throughput, yield, and quality
Analyze production test data to identify trends, drive root cause, and implement corrective actions
Support FAI, production qualification, and manufacturing process changes for new battery and motor builds
Troubleshoot test equipment and production issues directly on the factory floor
Develop and maintain test procedures, work instructions, and HV safety documentation
Own calibration, maintenance, and validation of manufacturing test equipment
Contribute to PFMEA and in-process quality control strategy
