System Simulation Engineer

Jan 25, 2024

Essential Duties and Responsibilities:

  • Thermal, mechanical, electro-chemical and other simulations of Li-ion cells up to product form factor: use of existing pre-developed tools and approaches, as well as developing new ones.
  • Develop and apply cell diagnostic tests and procedures, including automated data analysis tools, for the goal of model refinement, calibration, and validation.
  • Model and simulation supported experimental research and characterization of Thermal/Resistance/Mechanical/Safety cell level performance.
  • Analyze test results, detect issues and perform root cause analysis, using simulations.
  • Design of experiments (DoE) for finding the optimal cell parameters, directed by in-house developed cell simulations.

To perform the job successfully, an individual should demonstrate the following competencies:

  • MSc with at least 3 years of industry experience in: Electrochemical-related field (Physics, Chemistry, Chem. Eng., EE, Materials Eng. or similar), specializing in heat transfer modeling and analysis of electrochemical systems - preferably Li-ion batteries.
  • Proven ability and experience in modeling and analysis of cell internal resistance, and related thermal assessment.
  • Experience with FEM based analysis using COMSOL Multiphysics.
  • Programing skills in: Python, MATLAB or similar.
  • Analytical mindset and product-oriented approach: proven ability for end-to-end analyses.
  • Team player, able to share specific knowledge and insights, and their value, to others.
  • Advantage:
    - Thermal, mechanical, and electrical modeling of energy storage systems (major advantage).
    - Electrochemical / mass transfer (diffusion, incl. tortuosity) modeling abilities (major advantage).
    - Experience with Li ion battery cells, especially thermal & electrochemical tests.
    - Thermal runaway and propagation modeling.
    - Experience with automated scripts for testing and analysis.
    - Working in an Agile environment.
