Cryogenic Thermal Engineer for Superconducting Storage

Spinor Energy Inc.; Mountain View (CA); On-site; USD 140,000 - 190,000; Full time

Job summary

Spinor Energy Inc. seeks a Mechanical Engineer (Thermal / Cryogenics) to design and own its cryogenic system, used to supercool superconducting magnets to extreme temperatures.

You will lead from schematic to field deployment, coordinating with facilities and customers to accelerate infrastructure development. The role emphasizes first-principles mechanical design, materials and manufacturing, and end-to-end hardware lifecycle experience in a fast-paced, high-rate environment.

Qualifications

• Bachelor’s or Master’s degree in Mechanical Engineering, Physics, Aerospace Engineering, or equivalent practical experience.
• Strong first-principles fundamentals in mechanical design and manufacturing processes.
• Familiarity with GD&T (ASME Y14.5) for complex assemblies.
• Strong proficiency with thermodynamic first principles across heat transfer forms.

Responsibilities

• Own the design, analysis, and operation of Spinor’s cryogenic system from piece-part design to bring-up and field deployment.
• Design and optimize the thermal budget and management of heat flux to the magnet.
• Own component design/selection and hardware delivery for cryogenic and vacuum components (vacuum chambers/cryostats, MLI, supports, cryocooler interfaces).
• Own selection, packaging, and operation of cryogenic auxiliary equipment (cryocoolers, helium compressors, water chillers, vacuum pumps, water-cooling loops).
• Oversee deployment of cryogenic assets in-field operation and testing.
