Quantinuum is a quantum computing company headquartered in Broomfield, Colorado, formed in 2021 by combining Honeywell Quantum Solutions with Cambridge Quantum. It builds trapped-ion quantum computers such as its H-series systems and develops software including a quantum chemistry platform and compiler tools. Honeywell is its majority owner, and it has major sites in Broomfield, Minnesota, Cambridge and London in the UK, and offices in Japan and Singapore. It hires manufacturing and semiconductor packaging engineers, compiler and software engineers, physicists and finance staff.

We are seeking a Senior Advanced Semiconductor Packaging Engineer to work either at one of our Minneapolis, MN sites or at a supplier site in Malta, NY as a full-time Quantinuum employee to develop innovative and reliable packaging schemes for the highly-scaled ion traps in our quantum computers. The ideal candidate will be a mid-career engineer with a background in advanced packaging concepts. This role will work alongside ASIC designers, ion trap designers and fabricators, optical designers, and third-party vendors to prototype, design, and fabricate ion trap assemblies for our quantum computers. Candidates should expect to be immersed in a fast-paced, multi-functional, team-based challenging technical environment where an individual with talent and initiative can stand out and thrive.

All applicants for placement in safety-sensitive positions will be required to submit to a pre-employment drug test.

Key Responsibilities:

    • Develop and implement advanced packaging concepts for mechanical, thermal, electrical, optical, and detection interfaces to next-generation ion traps
      • Develop packaging strategies and processes for large-format ion trap chips with high I/O signal count and density
        • Work with vendors to implement and validate packaging processes
          • Support all stages of ion trap development to ensure compatibility with packaging
            • Interface with broader Quantinuum team to ensure ion trap packaging meets system requirements
              • Engage with 3rd parties to cultivate possible key partnerships, supplier relationships, and co-development opportunities

YOU MUST HAVE:

    • Bachelor’s degree minimum

WE VALUE:

    • PhD in Physics or Engineering
      • 7 years of experience with advanced large-area multi-chip semiconductor packaging technologies
        • 5 years of experience with large heterogeneous integration and 2.5-3D packaging techniques
          • 5 years of experience with high-density I/O technologies
            • Experience with photonic packaging and fiber-to-chip coupling is a plus
              • A proven track record of innovation and IP development
                • Experience working within a cross-functional team environment
