Engineering$100k–$145k/yrFull-time

Job Summary

The system engineering department is hiring a thermal mechanical engineer. You will be responsible for performing structural and thermal simulations to optimize the design of electro-optical sub-assemblies. Your work will directly impact on the performance and reliability of our quantum computer sub-systems.

Responsibilities

  • Develop detailed FEA/CFD models of components, packages, optical-electronic modules, and system-level assemblies using appropriate simulation tools such as ANSYS, COMSOL, or equivalent platforms.
  • Correlate FEA results with experimental measurements, prototype test data, and hardware observations to improve model fidelity and support simulation-driven design decisions.
  • Perform warpage and deformation analysis for multi-material assemblies, accounting for mismatch in thermal expansions, nonlinear material behavior, temperature gradients, and boundary conditions.
  • Develop thermal cycling and mechanical fatigue models to predict long-term reliability, including creep, stress relaxation, and interface degradation.
  • Identify mechanical risk drivers and recommend design, material, or process changes to improve robustness, manufacturability, and yield.
  • General design activities such as requirements management, materials and component selection, Design Failure Modes and Effects Analysis (FMEA), and tolerance analyses.
  • Develop end-to-end simulation workflows to automate processes, assess performance across diverse operating scenarios, documentation, and tools to improve efficiency, accuracy, and repeatability.
  • Analyze failures related to electro-optical assembly design and providing solutions.

Experience/Qualifications

  • M.Sc., or Ph.D in Mechanical Engineering, Electrical Engineering and Physics or related field.
  • 5+ years of hands-on modeling and simulation experience in the semiconductor industry.
  • Strong understanding of thermal conduction and convective heat transfer methodologies.
  • Deep knowledge of solid mechanics principles, including stress, strain, fatigue, creep, constitutive models of elastic, visco-plastic, and plastic materials.
  • Proficiency with simulation tools such as ANSYS (Mechanical, Icepak and Fluent), COMSOL, or equivalent, including nonlinear and transient analyses.
  • Working knowledge of lab-scale validation techniques.

Desired Skills/Experience

  • Experience with Ansys AEDT and Ansys Sherlock.
  • Understanding advanced semiconductor packaging, solder joints, and reliability modeling techniques.
  • Knowledge of common optical system specifications and optical component specifications.
  • Exposure to SOC thermal mechanical analysis.
  • Exposure to optical structural analysis.
