We are seeking an
ASIC Test & Characterization Engineer in our
Broomfield, CO, ASIC team to contribute to the development of Quantinuum's next-generation Apollo and Lumos quantum computers. This is an opportunity for an engineer or physicist to work directly on cryogenic semiconductor device and circuit characterization required for next-generation ion-trap quantum computers.
In this role, you will execute hands-on testing and characterization across multiple devices and technologies, working 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.
All applicants for placement in safety-sensitive positions will be required to submit to a pre-employment drug test.Key Responsibilities:- Perform hands-on cryogenic semiconductor device and circuit characterization, including test setup, execution, and data collection
- Partner with integrated product teams to validate ASICs critical to Quantinuum's quantum computer roadmap
- Design and develop electrical interfaces, fixtures, and test equipment for cryogenic environments
- Automate test execution and data analysis to enable fast, repeatable results
- Synthesize test results, understand their impact, and present to physicists, engineers, and leadership
- Operate cryogenic test chambers and associated lab equipment
- Collaborate with cross-functional teams to translate system-level requirements into clear, verifiable test plans.
- Translate system-level quantum computer requirements and customer needs into clear, verifiable test plans
- Thrive in a rapid-prototyping, R&D-focused environment where iteration speed matters
YOU MUST HAVE:- Bachelor's Degree Minimum
- Minimum 3+ years of relevant engineering, laboratory, or R&D experience, including graduate research
- Due to Contractual requirements, must be a U.S. Person defined as, U.S. citizen permanent resident or green card holder, workers granted asylum or refugee status
