Senior Mechanical Engineer (Cryogenics)

The role

The Senior Mechanical Engineer leads the design, development, testing, and integration of cryogenic systems and components. This role supports the commercialization of high-temperature superconducting technologies through advanced mechanical engineering and hands-on laboratory work.

What you will do

• Applies mechanical and cryogenic engineering principles to solve technical challenges.
• Designs and executes cryogenic test protocols.
• Prepares engineering documentation including drawings, specifications, and technical reports.
• Procures fabrication of custom cryogenic components and laboratory test hardware.
• Evaluates cryogenic system architectures and component selection.
• Develops engineering cost models for integrated superconducting systems.
• Identifies opportunities to improve system performance and reduce integration costs.
• Collaborates with internal teams, customers, suppliers, and strategic partners.
• Owns cryogenic engineering projects from concept through implementation.
• Provides technical mentorship and guidance to less experienced engineers.

Required qualifications

• Bachelor's degree in Mechanical Engineering, Cryogenic Engineering, Applied Physics, or a related engineering discipline.
• Four years of experience in an engineering role, including hands-on experience with cryogenic systems operating between 4 K and 77 K.
• Experience with HTS cable fabrication, superconducting magnet systems, current lead engineering, cryogenic systems, or related superconducting technologies.
• Demonstrated experience designing, building, and operating laboratory test equipment and experimental systems.
• Deep technical competence in mechanical and cryogenic system design, testing, integration, and execution.
• Strong understanding of thermal management, cryogenic system performance, and superconducting applications.
• Hands-on laboratory, prototyping, and troubleshooting experience.
• Strong communication and technical documentation skills.
• Ability to work independently in a research, development, and manufacturing environment.
• Ability to sit at a desk and view a computer screen for extended periods.
• Ability to move around the office, including occasional standing, walking, and bending.
• Ability to perform light lifting up to 20 lbs.

Nice to have

• Experience leading technical projects or engineering workstreams involving cryogenic or superconducting technologies.
• Experience performing heat load analysis, thermal modeling, and cryogenic system optimization.
• Knowledge of commercial cryocooler technologies, including Gifford-McMahon, Stirling, and pulse tube systems.
• Experience supporting superconducting cable, fusion energy, MRI, accelerator, or national laboratory programs.
• Experience collaborating directly with customers, technical partners, or external research organizations.
• Publications, patents, or significant technical contributions related to superconducting technologies or cryogenic engineering.
