The Role:

We are looking for a Staff Cryogenic Engineer for support and developing a cryogenic platform for diamond-based photonic interconnects between IonQ quantum processors. As a Staff Cryogenic Engineer, you’ll be part of a cross-functional team whose mission is to lead IonQ on its journey to build the world’s best quantum technologies to solve the world’s most complex problems.

In this role, you will be an integral part of the commercialization process for IonQ’s SiV quantum memories, with applications across quantum computing, networking, and sensing. You will develop and mature cryogenic subsystems for defect-center based quantum memory nodes. Specifically, this involves engineering R&D-scale subsystems and processes into robust, reliable elements deployable at other IonQ and/or customer sites, which can be efficiently maintained and/or updated as the technology evolves.

Responsibilities:

Customize commercially available cryostats for quantum memory-specific needs
Work with vendors to design and configure deployable cryogenic systems
Work with IonQ internal teams to improve the current cryogenic platforms
Provide operational support for the current fleet of cryostats

Requirements:

Masters in physics, applied physics, mechanical engineering, or closely related field
Experience working in cryo industry for 7+ years
Experience in designing and evaluating performance of complex cryogenic systems
Experience with operating and maintaining dilution, sorption, 1K cryostats
Experience with cryogenic wiring, sensors, and heaters
Experience with UHV systems in cryogenic environment: pumping, leak detection, sealing and joining techniques
Experience with CAD systems and manufacturing

Preferred Qualifications:

PhD in physics, applied physics, mechanical engineering, or closely related field
Experience working in cryo industry for 10+ years
Experience with managing complex production lines
Experience managing customer projects
Experience with free-space or fiber optics
Experience with working and integration of superconducting magnets
