Job Requirements

About the Role
We're hiring a simulation engineer for thermal and structural analysis for compact, high-density consumer electronics such as smart wearables. You'll run CFD and FEA simulations to predict and solve thermal, thermo-mechanical and reliability problems. Work Experience

Key Responsibilities
-
• Build and run conjugate heat transfer (CHT) simulations at system, board and component level, including natural convection, forced convection and radiation.
• Model the thermal behavior of SoCs, PMICs, batteries, displays, cameras and other heat-dissipating parts in tight enclosures.
• Run transient analyses of power profiles and use cases and support thermal throttling and power budget strategy.
• Evaluate cooling solutions: heat spreaders, graphite sheets, vapor chambers, TIMs, phase-change materials and airflow paths.
• Run thermo-mechanical stress and warpage analysis on PCBs, solder joints, packages and enclosures.
• Predict solder joint fatigue and reliability under thermal cycling.
• Couple CFD temperature fields into FEA for Multiphysics evaluation.
• Turn simulation results into clear design recommendations for cross-functional teams.
• Correlate models with lab data (thermocouples, IR thermography, thermal chambers) and improve model accuracy.
• Help define thermal test plans and DVT/PVT validation.
• Run design-of-experiments (DOE), sensitivity studies and optimization.
• Build simulation best practices, templates and automation scripts.

• Experience importing and simplifying CAD (Creo, SolidWorks, NX, DesignModeler, Space claim).
• Solid communication and reporting skills. Preferred Qualifications
• Experience with wearables, mobile devices, AR/VR or other compact consumer electronics.
• Knowledge of battery thermal behavior and safety.
• Scripting for automation and post-processing (Python, MATLAB, APDL).
• Experience with multiphysics coupling (electro-thermal, thermo-mechanical).
• Familiarity with JEDEC thermal standards and package characterization (θJA, θJC, compact thermal models).
• Experience with thermal test equipment and model correlation.
• Exposure to optimization tools (optiSLang, HEEDS, modeFRONTIER). Key Competencies
• Strong analytical problem-solving and engineering judgment.
• Able to balance simulation accuracy against program timelines.
• Works well with cross-functional, global teams.
• Takes ownership, with attention to detail.
