Quantinuum is hiring a principal mechanical design engineer for cryo vacuum systems in Broomfield, Colorado, to design and de-risk the next generation of trapped-ion quantum computing hardware. The work involves mechanical systems that must operate under cryogenic conditions and in UHV/XHV environments, hold precise optical alignment, and support scalable quantum computer architectures. The engineer works with research scientists, system architects, design engineers and lab engineers, turning ambiguous technical risks into designs, prototype tests and engineering recommendations. The posting asks for a hands-on designer comfortable with cryogenic, vacuum and optical-alignment constraints; the seniority and the hardware focus are what stand out.
