Roles and Responsibilities
Cryogenic Engineer
- Learn to operate and maintain a large fleet of dilution refrigerators located on UMD campus and at LQC. Maintenance responsibilities include monitoring the regular life cycle of various seals and gaskets, refilling/cleaning liquid nitrogen traps/etc.
- Create and perform diagnostic health checks to trouble shoot (e.g.) bad seals, malfunctioning valves, and suboptimal cooling power
- Maintain operation of a Cryomech helium liquefier. Monitor lab-wide usage and boil off. Trace sources of leaks to improve recovery efficiency. Refill helium dewars for users.
- Actively document the status of all equipment. Create standard operating procedures for each type of system and assist researchers with operation.
- Coordinate with vendors to replenish stock of cryogens and other consumables/replacement parts.
- Coordinate and assist with installation of equipment
Hardware Engineer
- Help researchers troubleshoot any malfunctioning measurement equipment. Communicate with the corresponding companies/vendors to coordinate necessary repairs.
- Collaborate with software developer to enhance functionality across measurement infrastructure
- Stay up to date with the latest industry trends in measurement automation and high-precision electronics to propose and implement improvements where necessary
- Assist with basic PCB design and assembly, including wire-bonding
