Cell Engineering Technician
About Tesla

Tesla's goal is to accelerate the world's transition to electric mobility with a full range of increasingly affordable electric cars. California-based Tesla designs and manufactures EVs, as well as EV powertrain components for partners such as Toyota and Daimler. In Q1 of 2013 Tesla has delivered more than 10,000 electric vehicles to customers in 31 countries. Tesla's Model S is the world's first premium sedan designed and engineered from the ground up as an electric vehicle and was named Automobile Magazine's 2013 Automobile of the Year ® and Motor Trend's prestigious 2013 Car of the Year ® .
The Role

This technician will assist cell engineering efforts to further the understanding of cell degradation, cell performance and cell safety characteristics at the electrode level. The candidate will benchmark and quantify differences in fresh versus aged batteries to identify root causes of degradation.
Responsibilities

Perform cell level destructive physical analysis (DPA) and other analytical techniques to analyze mechanisms of energy and power loss in lithium ion chemistries.
Build coin cells and pouch cell to evaluate cell performance.
Execution and maintenance of lithium ion cell tests using cell cycle equipment (e.g. Arbin or Maccor), temperature/humidity chambers and chillers.
Write test plans, propose design of experiments and summarize results in test reports.
Design and build fixturing for battery testing.
Use data manipulation skills and data visualization techniques to convey test results to cell engineers.
Be a member of a cross functional product development team to help determine the ideal cell chemistry and design for electric vehicle applications.

Requirements

Experience working in a glove box environment.
Hands-on lithium ion battery cell testing. Understanding of lithium ion cell safety and its inherent dangers.
Familiar with analytical equipment used in analyzing battery electrodes (SEM, XRD, TEM, EIS, GC-MS, etc)
Experience working with multiple Li-ion cell chemistries including LCO, LMO, NCA, FePO4
Familiar with the degradation mechanisms in lithium ion batteries is a plus but not required.
Above average manual dexterity and average visual acuity are required in order to perform delicate assembly tasks.
Previous use of ARBIN or MACCOR equipment or similar electrical battery test equipment is a plus
Experience soldering and crimping.
Familiar with calibration and maintenance of test equipment.
Working knowledge of Excel and Powerpoint
