Job description

We are seeking a highly qualified Deployment Physicist, On-premises Installation based in our London or Cambridge locations to install and service Helios systems worldwide for our Hardware-as-a-Service business.

Helios is our current-generation quantum computer with 98 physical qubits and >99.9% two-qubit fidelities that is available through the cloud. Our first on-premises unit will be installed in Singapore with other locations to follow.

The ideal candidate will be based at this Quantinuum site but will travel to other Quantinuum sites for training and customer sites to support Helios installs around the world via extended travel. To develop deep familiarity with the Helios hardware and software, the candidate will support integration, validation, and shipment preparation activities in the US in-person (if based in the US or via travel otherwise) and remotely. They will then be part of the team installing and validating performance of the system at a customer site. As we move through our increasingly ambitious roadmap, they will contribute to future post-Helios on-premises offerings during design, execution, and deployment.

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

Key Responsibilities

• Successful installation of Helios systems on customer premises including preparation for shipment, relocation, installation, and validation
• Improve and mature plans and work instructions for the above activities
• Act as the team's atomic physics and qubit operations expert, explicitly owning qubit-based integration and validation tasks during deployment
• Remote support and on-site service (as necessary) of Helios systems with the support of subject matter experts and a global team
• Participate in integration and validation of Helios systems at Quantinuum prior to deployment
• Contribute to and support future on-premises hardware offerings post-Helios
• Have utmost focus on business success, technical progress, and professional interactions for both you and the team
• Travel (domestically and internationally) up to 3 months at a time during deployments and 25% otherwise

You Must Have

• Ph.D. completed
• Minimum 8 years of post-graduate experience (M.S. or Ph.D. inclusive) as a technical contributor or leader in an atomic physics or quantum computing role
• Eligibility to complete international travel
• 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
• Due to national security requirements imposed by the U.S. Government, candidates for this position must not be a People's Republic of China national or Russian national unless the candidate is also a U.S. citizen.

We Value

• A deep knowledge of trapped-ion-based technology, high-performance quantum computing, and technical hardware integration and validation
• A proven track record of atomic physics research and development as evidenced by scholarly publications, successful program execution, and/or launched products
• Experience with lasers, laser cooling, atom trapping, cryogenics, ultra-high vacuum systems, analog and digital electronics, laboratory hardware control, Python, physical modelling, and data analysis
• A strong drive to exceed performance and schedule expectations
• Commitment to documenting work via shared note taking as well as the creation and maintenance of standard work documentation, test plans, troubleshooting guides, and configuration documentation
• Strong communication and collaboration skills
