About the Role

We are seeking an experienced Thermal Mechanical Design Engineer to join our Cryogenic Engineering Department. This role will be heavily involved in the thermal mechanical simulation and design for our quantum computer, interacting with multiple teams internally and suppliers externally.

Key Responsibilities
  • The Thermal Mechanical Engineer focuses primarily on the highly integrated electronic optical assembly to support our quantum computer.
  • Applying knowledge of heat transfer, fluid mechanics, and structural mechanics to the development of optical electronics assembly under cryogenic conditions.
  • Develop methodologies for chip power modeling and measurement, characterization of power features, correlate chip behavior with simulations and provide design feedback.
  • Analyzing field issues related to electronic optical assembly design and providing solutions where required.
  • General design activities such as requirements management, materials and component selection, Design Failure Modes and Effects Analysis (FMEA), and tolerance analyses.
  • Assisting and/or directing vendors to develop necessary manufacture processes.
  • Actively participating in cross-functional project teams through all phases of product development to ensure successful execution of innovative and best-in-class designs.
Requirements and Qualifications
  • B.Sc., M.Sc., or Ph.D in Mechanical Engineering, Aerospace Engineering, Nuclear Engineering, or Physics.
  • Software tools – Mathcad, Matlab, IcePak, ANSYS Workbench, Fluent, SpaceClaim, Solidworks, NX.
  • Demonstrated use of advanced analysis tools to solve thermal/fluid challenges with respect to optical and electronic assembly at the appropriate level of detail – Finite Element Analysis (FEA) and Fluid Dynamics (CFD).
  • Solid understanding of and experience matching thermal models to experiment results.
  • Thoroughly documenting design inputs and outputs.
  • Ability to adapt changes and handle multiple assignments.
  • Excellent written and verbal communication skills.
Desired Skills/Experience
  • Experience with multiple material performance, design constraints, and manufacture constraints under cryogenics condition.
  • Knowledge of common optical system specifications and optical component specifications.
  • Experience in feeding thermal model results into structural models to determine optical component movements/deformations (STOP analysis).
  • Exposure to CPU/GPU/SoC architecture and HW-SW co-design is a plus.

PsiQuantum offers a competitive base salary range of $130,000—$180,000 USD.
