About this role
Key Responsibilities
- Design, model, and integrate cryogenic cooling systems (conduction-cooled, cryo-fluid loops, or liquid helium/nitrogen systems) for HTS magnet assemblies.
- Perform thermal, fluid, and structural FEA modeling (e.g., ANSYS, COMSOL) to optimize temperature profiles, cooling margins, and quench behavior.
- Select, specify, and procure cryogenic hardware, including cryocoolers, thermal straps, current leads, vacuum vessels, and instrumentation.
- Lead cryogenic testing, commissioning, and validation of HTS magnet prototypes from 20K up to 77K environments.
- Troubleshoot thermal leaks, vacuum degradation, and cryogenic system integration issues during test campaigns.
- Mentor junior engineers and collaborate directly with magnet designers, electrical engineers, and manufacturing teams.
Required Qualifications
Experience:
- 8+ years of dedicated professional experience in cryogenic engineering, specifically applied to superconducting magnet systems (HTS preferred; LTS with strong HTS understanding is considered).
Education:
- Bachelor’s or master’s degree in mechanical engineering, Aerospace Engineering, Applied Physics, or a related field (Ph.D. preferred).
Technical Skills:
- Deep expertise in vacuum technology, and low-temperature material properties.
- Proven experience in cooling superconducting magnets – MRI, accelerators or fusion systems
- Proven experience with cryogenic refrigeration systems (Gifford-McMahon, Pulse Tube, or Stirling cryocoolers or large cryoplants).
- Proficiency in thermal simulation software (ANSYS, COMSOL, or Thermal Desktop) and CAD systems (SolidWorks or NX).
- Practical laboratory experience with cryogens (LN_2, LHe), vacuum leak detection, and sensor integration (cernox, thermocouples).
Preferred Qualifications
- Experience with HTS tape technologies (2G REBCO) and quench protection thermal modeling.
- Hands-on design of high-current thermal leads (binary or HTS lead assemblies).
- Background in building cryogenic test facilities for fusion energy, MRI/NMR systems, high-energy physics, or aerospace HTS applications.
Company Benefits:
- Comprehensive health benefits (e.g. medical/dental/vision)
- Employee equity stock options
- 20 days PTO
