Cryogenic Engineer
Apply physics principles to design reliable systems and products.
What is a Cryogenic Engineer?
Cryogenic engineers design, develop, and operate systems that function at extremely low temperatures (below -150°C or -238°F). They work with cryogens like liquid helium and nitrogen to create environments for research, industrial processes, and advanced technologies.
You spend most days at a desk or console: running penetration tests, coordinating continuous monitoring, scanning for vulnerabilities, and overseeing plans that safeguard files and backups for cryogenic controllers. When alarms or anomalies appear you investigate breaches, collect logs, and coordinate containment to protect temperature-sensitive hardware and samples. Routine work includes training staff on security practices and assessing the quality of controls using performance indicators.
