We are seeking anASIC Test & Characterization Engineer in ourBroomfield, 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
WE VALUE:
- Experience testing and characterizing semiconductor devices, ASICs, or analog/digital circuits
- Experience using Python, or similar programming languages, for test automation, data acquisition, or analysis
- Authorization to work in the United States without current or future visa sponsorship
- Hands on experience with low noise analog electronics
- Understanding of EMI/EMC, grounding, and return current paths in sensitive systems
- Hands-on experience translating electrical characterization results into models for circuit design
- Experience with cryogenic test chambers
- Familiarity with the electrical engineering challenges of quantum computers, ion traps, or similar ultra sensitive systems
- Clear communicator who produces right sized, effective design and test documentation
