Sr. Staff Thermo-Mechanical Engineer

Sr. Staff Thermo-Mechanical Engineer to join Marvell’s Advanced Technology Infrastructure team. Lead advanced thermo-mechanical finite element simulations to evaluate stress, strain, deformation, and structural integrity of test sockets, thermal heads, interconnects, fixtures, handlers, and package interfaces used in high power XPU and Silicon Photonics programs. Lead warpage and deformation analyses for multi-material assemblies; develop thermal cycling and mechanical fatigue models; create process-aware mechanical models capturing assembly, cure, reflow, compression, and load-path evolution through manufacturing and test. Translate package/test infrastructure requirements into mechanical design constraints and reliability metrics for early architecture decisions. Correlate simulations with mechanical testing, thermal cycling data, warpage metrology, and strain measurements to validate models. Identify mechanical risk drivers and recommend design/material/process changes to improve robustness, manufacturability, and yield. Support root-cause analysis of lab or field issues related to cracking, delamination, contact degradation, or excessive warpage. Develop simulation methodologies and best practices to improve consistency across programs. Partner with thermal, packaging, test, reliability, and manufacturing teams to ensure mechanical compatibility and system-level alignment; interface with external vendors/manufacturers on material selection and tolerances. Document and communicate results through technical reports and executive summaries. Requires collaboration across multiple engineering domains and potential leadership of cross-organ infrastructure programs.
