Develop thermal and mechanical characterization methods to evaluate heat load, thermal performance, temperature cycling, and product reliability at cryogenic temperatures.
Design, build, and improve test fixtures, instrumentation, adapters, and laboratory hardware required for characterization and qualification.
Analyze test data to identify trends, anomalies, failure mechanisms, and opportunities for product and process improvement.
Lead technical troubleshooting and root-cause investigations related to cryogenic testing and product performance.
Develop automated test methods and improve laboratory processes to increase throughput, repeatability, data quality, and efficiency.
Establish test methods, acceptance criteria, and qualification requirements in collaboration with R&D, engineering, quality, manufacturing, and customers.
Generate technical test reports and provide technical support for customer qualification and product development programs.
Mentor engineers and technicians in cryogenic testing, instrumentation, data analysis, laboratory practices, and safe operation of cryogenic equipment.
QUALIFICATIONS:
BS in Mechanical Engineering, Electrical Engineering, Physics, Materials Science, or related field; MS preferred.
5+ years of experience in cryogenic testing, characterization, test engineering, interconnect development, or a related field.
Hands‑on experience with cryogenic systems, cryostats, dilution refrigerators, vacuum systems, or low‑temperature test equipment.
Experience developing and executing electrical, thermal, mechanical, and/or environmental characterization and qualification testing.
Strong understanding of cryogenic testing principles, including heat transfer, thermal conduction, radiation, temperature measurement, and cryogenic materials behavior.
Experience with cryogenic electrical/RF test equipment such as VNAs, TDRs, multimeters, temperature controllers, and data‑acquisition systems.
Experience developing test fixtures, instrumentation, automated test methods, and laboratory hardware.
Strong data analysis, troubleshooting, technical writing, project management, and communication skills.
