Expertise in ultra low temperature engineering and design with a focus on thermal transport, mechanical compatibility, or liquefaction
Demonstrated experience on system design and integration teams.
Demonstrated experience working in laboratory environments and hands-on experience with ultra-low temperature installations.
Demonstrated experience building thermal, fluid flow, and materials models.
Experience with both wet and dry cryogenic systems.
Experience collaborating with a multidisciplinary team of engineers, scientists, and non-domain experts supporting system design.
Highly self-motivated, with the ability to work independently without guidance.
Advanced verbal and written communications skills.
Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the E.S. as a refugee or granted asylum.

Desired

Familiarity with instrumentation controls and scripts, specifically PyVISA and SCPI commands.

Familiarity with project life-cycle management and the AGILE structure.

Cryogenics handling safety training.

Experience with vendor interactions and supply management.

Experience working in a start-up or quick paced environment.

Background supporting team expansion and providing mentoring to junior contributors.

Experience working on R&D teams or developing low TRL products.
