Original job description

Mechanical Engineer -- Vacuum Opto Mechanical Assembly - 822 We are seeking a Lead Mechanical Design Engineer in our Broomfield, CO location to apply their skills to the development of our next generation large-scale quantum computers. In this role, you will own the mechanical design of a precision quantum hardware subsystem that physically houses the core of our ion trap quantum computer. This subsystem integrates an ultra-high vacuum chamber, ion trap hardware, precision beam delivery and detection optics, electrical control components, and associated structural, thermal, and alignment features. The work spans early-stage architecture, detailed opto mechanical design, tolerance and stability analysis, hands on prototyping, and iteration alongside physicists, electrical engineers, and systems engineers. ### Key Responsibilities: - Lead the mechanical development and deployment of precision, multi-functional, quantum hardware assemblies from early concepts to detailed design to final procurement for next-generation trapped-ion quantum computers. - Design mechanical interfaces, mounting structures, and housing modules for complex optical, electrical, cryogenic, and vacuum subsystems. - Design precision environmental control systems. - Work with subsystem leads and systems engineers to maintain thorough interface control documents (ICDs). - Derive detailed mechanical subsystem and component requirements from higher-level requirements. - Maintain thorough, version-controlled CAD models and BOMs. - Partner with lab validation & integration teams to build and test prototype assemblies. - Complete FEM models to predict the structural, electrical, thermal, magnetic, and acoustic performance of complex subsystem assemblies. - Partners with quantum physicists and subsystem leads to optimize optical, electrical, cryogenic, and vacuum subsystem designs. - Partner with manufacturing team leads to optimize the lead time, SWAP-C, and uptime of subsystems. - Communicate findings and design proposals to larger technical, management, and executive teams. - Mentor junior engineers. ### YOU MUST HAVE: - Bachelor's degree minimum - 5+ years of experience involving one or more of the following areas: cryogenic system design, vacuum systems, thermal modeling, qubits, atomic physics, spectroscopy, optics, electronics, or laboratory work in the physical sciences preferred. - 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. - 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 ### WE VALUE: - 8+ years' experience in scientific research and development, engineering, or leadership roles - Experience leading a team in designing or operating cryogenic and/or XHV systems. - Strong organizational and leadership skills, and experience in working with customers and partners. - Experience with Onshape, Comsol, and Ansys tools. - Experience in magnetic field simulation and magnetic coil design. - Experience performing simulation and modeling to inform experiments. - Experience with control systems for data collection, signal processing, and analysis. - Experience with electrical and fiber optic feedthroughs. - Experience with extreme-high vacuum environments. - Experience with trapped ions and ion transport. - Excellent written and oral communication skills, with published results within their field of research. Compensation & Benefits: Incentive Eligible -- Range posted is inclusive of bonus target The pay range for this role is $152,000 -- $190,000 annually. Actual compensation within this range may vary based on the candidate's skills, educational background, professio al experience, and unique qualifications for the role.
