Work Type: Contract
Work Schedule: On-site
What You’ll Do
-
Execute Pack-Level Test Plans — Run complex electrical, thermal, and battery cycler test plans specifically at the pack level, delivering high-quality dataset outputs on schedule.
-
Build Data Automation & Ingestion Pipelines — Develop and maintain Python scripts to automate data ingestion, process raw cycler logs, and streamline continuous test data analysis.
-
Analyze & Investigate — Process high-volume test data to support algorithm engineers in evaluating pack behavior and investigating electrical or thermal anomalies.
-
Troubleshoot & Maintain — Diagnose equipment, BMS firmware interactions, and pack-level sample failures; repair and calibrate test hardware as needed.

Automate Validation Workflows — Co-develop automated testing frameworks and hardware-in-the-loop (HIL) setups alongside test engineering peers.
What You Bring (Must-Haves)
-
Pack-Level Battery Testing — Extensive hands-on experience running test profiles, qualification protocols, and diagnostic routines on multi-cell lithium-ion battery packs using high-channel battery cyclers (e.g., Arbin, Maccor, Chroma).
-
Python Data Automation & Ingestion — Strong Python programming skills dedicated to test automation, raw data ingestion, ETL/pipeline creation, and processing large time-series datasets.
-
Hardware & Circuit Debugging — Practical experience working directly with electrical circuits, source meters, oscilloscopes, multimeters, and physical pack assembly hardware.
-
System Troubleshooting — Proven track record of diagnosing complex electrical, firmware, and system-level issues during validation.
