About the job
Requirements
- A Master of Science degree.
- Experience in thermal and computational fluid dynamics engineering simulations.
- Experience with Ansys Electronics Desktop (AEDT) IcePak.
- Experience coding in Python.
Responsibilities
- Develop state-of-the-art thermal, computational fluid dynamics, and multiphysics finite-element models of cell, pack, and battery management system subsystems.
- Provide design and trade-off guidance to product development teams through early-stage simulations, particularly for fast charging and high-power functions.
- Generate models or capabilities to convert power maps into thermal outputs.
- Perform advanced thermal computer-aided engineering simulations to evaluate and understand boundary conditions at cell, pack, and battery management system subsystems around battery packs and within the system.
- Use appropriate tools and solvers to generate simulation models and results.
- Work with test and reliability labs to develop physical test methods and gather data for results validation.
- Work with system teams to develop detailed submodels for assembly-level simulations.
- Develop optimized workflows or reusable templates for regularly required thermal simulations.
- Work with computer-aided engineering vendors to improve functionality in support of the group's needs.
- Participate in new technology exploration, including applying artificial intelligence and machine learning to physics-based simulations.
- Contribute to developing simulation-driven design workflows.
- Model thermal performance of battery systems across Apple products.
- Collaborate with battery module, product, battery modeling, and cell engineering teams from early design stages to analyze and inform product design.
- Provide cross-functional design guidance on product-feature thermal impacts and improve thermal performance through design changes and mitigations.
Desired Qualifications
- A PhD and 10 or more years of relevant industry experience.
- Experience in transient thermal simulations of assemblies built using mechanical computer-aided design and electrical computer-aided design inputs.
- Experience in electronic heating and cooling and computational fluid dynamics.
- Experience in artificial intelligence and machine learning, including surrogate modeling and digital twins.
- Experience with NX, COMSOL, and Cadence/Allegro.
- Experience in electronics layout design.
- Experience defining and leading a technical development roadmap.
- Experience in a technical lead role and/or managing engineering teams.

Simplify's Take
What believers are saying
- Business demand is growing: Apple reported $109.4 billion revenue in the June 2026 quarter, up 16% year over year.
- Eligible US employees get learning support: Apple reimburses career-related tuition and runs Apple University classes.
- Services earn richer margins: Apple reported 75.6% services gross margin in the June 2026 quarter, versus 40.1% for products.
What critics are saying
- Assembly depends on Asian partners: Apple outsources substantially all final hardware assembly, reducing direct control over production.
- iPhone concentrates demand risk: the product generated 49.6% of Apple revenue in the June 2026 quarter.
- Student support shifts take evenings: Apple College Advisors typically work three evening shifts and one weekend shift weekly.
What makes Apple unique
- Its chips link hardware and software: Apple designs M-series processors and developer frameworks tuned to their unified memory.
- Stores double as service hubs: Apple combines device sales, Genius Bar technical help and in-person learning sessions.
- It owns a spatial operating system: Apple Vision Pro runs visionOS, controlled through eyes, hands and voice.
