Job description

Mechanical Engineering Intern for Photonics Physics Package R&D - 996 at Quantinuum, US Broomfield, CO. A intern-level full time position in the Internships/Students team, listed under hardware engineering.

We are seeking a Mechanical Engineering Intern for Photonics Physics Package R&D in our Broomfield, CO location to support trapped-ion integrated photonics R&D team.

Our diverse team of engineers and scientists develops optics and integrated photonics technologies that enable scaling of our trapped-ion quantum computers from our current 98-qubit Helios system to our future Lumos system with hundreds of thousands of qubits. The data, designs, and expertise from our group inform our next-generation systems, from the overall architecture to the tiniest of details. We are looking for more collaborative engineers and scientists to join our cross-disciplinary team.

WE VALUE

• Curiosity towards vacuum systems, cryogenics, precision mechanics, optics, photonics, or scientific instrumentation and their connection to quantum computing
• Strong problem-solving skills with a willingness to troubleshoot complex multidisciplinary systems.
• Ability to communicate technical concepts clearly and work effectively in multi-disciplinary teams.
• Experience with CAD software such as SolidWorks or Onshape.
• Hands-on experience designing, fabricating, or assembling mechanical systems in a laboratory, research, academic, or industry setting.
• Familiarity with engineering drawings, GD&T, tolerance stack-up analysis, and design for manufacturing principles.
• Experience operating rapid prototyping tools or working with machine shops and vendors.
• Familiarity with structural, thermal, vibration, or finite element analysis methods.
• Programming or scripting experience (Python, MATLAB, LabVIEW, or similar) for automation, analysis, or test equipment control.

Quantinuum is a leading quantum computing company delivering a full stack platform designed to make quantum computing deployable in real-world environments.

Responsibilities

• Support the trapped-ion integrated photonics R&D effort through one or more of the following:
• Support the design, build, integration, and/or operation of cryogenic ultra-high vacuum (UHV) test systems used to evaluate and scale next-generation quantum computing technologies.
• Create and maintain 3D CAD models, detailed engineering drawings, and assembly documentation for custom mechanical components, fixtures, and test hardware.
• Collaborate with engineers and scientists to fabricate, assemble, troubleshoot, and improve experimental ion trap test systems.
• Collect and analyze data to validate hardware performance, reliability, and manufacturability.
• Support root cause investigations and failure analysis activities to identify design improvements and enhance system performance.
• Contribute to design reviews, engineering documentation, and configuration management processes.
• Work closely with the Integrated Photonics team to design and build fixtures, tooling, and test hardware supporting photonic device characterization and validation.

Requirements

• Actively pursuing a bachelor’s degree in mechanical engineering or related degree
• Graduating after December 2027
• Due to Contractual requirements, applicants for employment for this position must have work authorization that does not now or in the future require sponsorship of a visa for employment authorization in the United States and with Quantinuum. (i.e., H1-B visa, F-1 visa (OPT), TN visa or any other non-immigrant 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.
