We are seeking a Cryogenic Semiconductor Characterization Engineer to join our Broomfield, CO, team and play a hands-on role in developing Quantinuum’s next-generation Apollo and Lumos quantum computers. This is a rare opportunity for an early-to-mid-career physicist or engineer to stand up, own, and operate cryogenic semiconductor characterization from the ground up, directly shaping the technologies that power our system roadmap.
In this role, you won’t just run tests—you’ll define the cryogenic characterization strategy, build the infrastructure, and drive execution across multiple systems and technologies. You’ll work side-by-side with ASIC designers, system architects, and experimental physicists in a fast-paced R&D environment where initiative, creativity, and technical depth truly matter.
If you’re excited by complex hardware, ultra-low-temperature physics, and seeing your work make it into real quantum machines, this role is for you.
