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.\nIn 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.\nIf 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.\nAll applicants for placement in safety-sensitive positions will be required to submit to a pre-employment drug test.\nKey Responsibilities:\nPerform hands-on cryogenic semiconductor device and circuit characterization, including test setup, execution, and data collection\nPartner with integrated product teams to validate ASICs critical to Quantinuum’s quantum computer roadmap\nDesign and develop electrical interfaces, fixtures, and test equipment for cryogenic environments\nAutomate test execution and data analysis to enable fast, repeatable results\nSynthesize test results, understand their impact, and present to physicists, engineers, and leadership\nOperate cryogenic test chambers and associated lab equipment\nCollaborate with cross-functional teams to translate system-level requirements into clear, verifiable test plans.\nTranslate system-level quantum computer requirements and customer needs into clear, verifiable test plans\nThrive in a rapid-prototyping, R&D-focused environment where iteration speed matters\nYOU MUST HAVE:\nBachelor’s Degree Minimum\nMinimum 3+ years of relevant engineering, laboratory, or R&D experience, including graduate research\nDue 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\nWE VALUE:\nExperience testing and characterizing semiconductor devices, ASICs, or analog/digital circuits\nExperience using Python, or similar programming languages, for test automation, data acquisition, or analysis\nAuthorization to work in the United States without current or future visa sponsorship\nHands on experience with low noise analog electronics\nUnderstanding of EMI/EMC, grounding, and return current paths in sensitive systems\nHands-on experience translating electrical characterization results into models for circuit design\nExperience with cryogenic test chambers\nFamiliarity with the electrical engineering challenges of quantum computers, ion traps, or similar ultra sensitive systems\nClear communicator who produces right sized, effective design and test
