Battery Thermal Engineer

Title: Battery Thermal Engineer

Location: Cupertino, CA

Fulltime

Job Summary:

As a member of the Battery Modeling team, onsite in Cupertino, CA, the Battery Thermal Engineer, expect in ICEPAK AEDT will be responsible for thermal modeling across all products, developing state-of-the-art thermal and multi-physics finite volume (FE) models of cell, pack, and BMS sub-systems.

Battery Thermal Engineer requires an MS or PhD plus a minimum of three years of industry experience, a mechanical engineering background with a strong foundation in computational fluid dynamics and thermal modeling, and, as a mandatory requirement, an expert-level skillset in Ansys Electronics Desktop and Icepak within AEDT. Proficiency in Python or another scripting language is required. Preference is given to candidates with an MS or PhD plus five years of relevant experience, familiarity with Cadence Allegro and electronics layout design, familiarity with lithium-ion cells and battery packs, familiarity with NX and COMSOL, and direct experience in electronics cooling.

Expected to deliver models and capability that convert power maps into thermal outputs; advanced thermal and CFD simulations evaluating boundary conditions at cell, pack, and BMS sub-system levels as well as system-wide; optimized workflows and reusable templates for recurring thermal simulations; documented thermal modeling best practices; exploration of new analysis types and solutions including topological optimization; and reduced-order models extracted from CFD simulations to accelerate exploratory studies.

Responsibility:

Generate models/capability to convert power maps into thermal outputs

Perform advanced thermal/CFD simulations to evaluate boundary conditions at the cell, pack, and BMS sub-system levels, as well as system-wide
