Job Description
We are seeking a Principal Vacuum Interconnect Architect – Quantum Hardware in our Broomfield, CO location to lead development of scalable interconnect architectures for our next-generation large-scale quantum computers. Future systems such as Lumos will require interconnect solutions that support orders-of-magnitude growth in qubit count, signal density, optical access, thermal performance, vacuum compatibility, and system reliability. This role is intended for a senior technical leader who can operate independently, define requirements, evaluate new technologies, guide prototype development, and make high-impact recommendations that shape the system architecture.
The ideal candidate will have deep expertise in one or more optical interconnects, electrical interconnects, advanced packaging, cryogenic systems, UHV/XHV vacuum systems, photonics, RF/electrical systems, or precision hardware for complex scientific instruments. They should be comfortable working across disciplines and translating high-level architecture goals into practical subsystem requirements, design trades, prototypes, and validation plans.
All applicants for placement in safety-sensitive positions will be required to submit a pre-employment drug test
- Lead the architecture and technical strategy for scalable optical and/or electrical interconnect solutions for next-generation quantum computing systems.
- Develop interconnect concepts capable of supporting million-qubit-scale system requirements, including high-channel-count connectivity, cryogenic operation, XHV compatibility, thermal constraints, signal integrity, optical performance, manufacturability, and reliability.
- Work closely with system architecture, trap fabrication, cryogenic ASIC, optics, electrical engineering, vacuum, cryogenic, mechanical, and packaging teams to define interconnect requirements and interfaces.
- Identify key technical risks and define prototype tests to retire those risks quickly and quantitatively.
- Oversee the design, fabrication, assembly, and validation of prototype interconnect hardware and subsystem demonstrators.
- Evaluate manufacturability, scalability, reliability, assembly flow, testability, and integration risk for proposed interconnect architectures.
- Mentor and develop junior engineers.
- Work closely with a small, cross-functional design team to rapidly conceptualize, validate, and deliver high-reliability designs and prototypes that solve key optical and electrical packaging challenges.
- Work with subsystem teams to identify potential technology insertions into the architecture.
- Partner with fabrication and electrical engineering teams to co-design trap-package, ASIC, and interposer-level packaging solutions.
- Communicate findings and design proposals to technical, management, and executive audiences.
- Generate and present subsystem design trade studies and analyses.
- PhD Required
- Minimum of 12 years of experience (PhD inclusive) involving one or more of the following areas: cryogenic system design, optical interconnect, electrical interconnect, vacuum systems, thermal modeling, qubits, atomic physics, spectroscopy, optics, electronics, or laboratory work in the physical sciences.
- 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.
- 15+ years of experience in scientific research and development, advanced engineering, systems architecture, or technical leadership roles preferred.
- Deep expertise in optical interconnects, fiber-optic packaging, photonic interposers, optical feedthroughs, electrical feedthroughs, high-density signal routing, cryogenic interconnects, or advanced hardware packaging.
- Experience using simulation and modeling to inform design decisions, including thermal modeling, FEA, optical modeling, signal-integrity modeling, or vacuum/thermal analysis.
- Strong written and oral communication skills, including the ability to present complex trade studies and recommendations to technical and non-technical audiences.
- Demonstrated ability to lead complex technical design efforts involving multiple engineering or scientific disciplines.
- Experience designing, building, testing, or validating complex hardware prototypes.
- Ability to operate with a high degree of autonomy and technical ownership.
- 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
