About the role

Apple's Battery Engineering team seeks an experienced FEA Engineer to design, qualify, and manufacture battery systems for Apple devices. The role focuses on high-fidelity simulations to inform design decisions, validate against experiments, and scale workflows across multiple programs, enabling faster development, improved safety, and breakthrough performance.

Responsibilities

  • Develop high-fidelity finite element analyses to predict battery performance prior to physical prototyping
  • Deliver simulation insights that directly shape design decisions and qualification outcomes for shipping products
  • Validate model predictions against experimental data and iterate to improve model accuracy and reliability
  • Develop and implement advanced structural, mechanical, thermal, and electrochemical models at the forefront of battery simulation technology
  • Capture intricate design details, cell chemistry behavior, and load cases spanning multiple length and time scales
  • Build coupled multi-physics models that accurately represent the complex interactions within battery systems
  • Design and deploy automated, end-to-end workflows from geometry creation through validated results
  • Leverage agentic automation, surrogate modeling, reduced-order modeling, parameterized design of experiments (DOE), and job automation for rapid design exploration, calibration, and optimization
  • Scale simulation capabilities to support multiple concurrent product programs
  • Experimental Validation and Material Characterization
  • Design novel, non-standard test methods to calibrate material models and validate simulation predictions
  • Define instrumentation and measurement strategies that provide high-quality data for model validation

Qualifications

  • MS degree in Mechanical Engineering, Computational Mechanics, Applied Mechanics, Materials Science, Applied Physics, or similar
  • Experience with commercial finite element analysis software such as Abaqus
  • Experience with advanced simulation techniques such as nonlinear constitutive modeling and modeling of high speed events and large deformations
  • Experience programming in Python
  • Experience building, debugging, and calibrating finite element models
  • PhD and 3+ years relevant industry experience
  • Experience building, debugging, and calibrating finite element models
  • Experience with coupled thermal-mechanical or electrochemical-mechanical modeling
  • Experience with LS-DYNA, ANSYS, or COMSOL
  • Exposure to physics-based machine learning methods for surrogate modeling or model order reduction
  • Custom solver development or user-defined material model implementation experience
  • Industry experience in battery mechanics, electrochemistry, or energy storage systems
  • Experience validating complex models against experimental data
  • Experience designing and executing physical tests for material characterization or model validation
  • Familiarity with high-performance computing (HPC) environments and version-controlled software development workflows
