Headquartered in Broomfield, Colorado, Quantinuum is a full-stack quantum computing company formed through the merger of Honeywell Quantum Solutions and Cambridge Quantum. The firm develops trapped-ion quantum hardware alongside specialized software platforms, including quantum chemistry engines, compiler toolkits, and quantum-cybersecurity applications.

We are seeking a Senior Advanced/Lead Optical Systems Engineer in our Broomfield, CO location.

All applicants for placement in safety-sensitive positions will be required to submit to a pre-employment drug test. This role offers the opportunity to work on a hybrid schedule. Employees are expected to work at their assigned location and may work remotely up to 2 days per week, with approval.

Key Responsibilities:

  • Create and manage requirements, interface definitions, and architecture definition documentation for one or more optical subsystems of a future trapped-ion quantum computer, in collaboration with the subsystem technical teams and external suppliers/partners.

  • Derive and manage traceability of subsystem artifacts to system-level requirements and architecture definition documentation, in collaboration with system-level architects and systems engineers.

  • Trade design options in collaboration with subsystem technical teams and external suppliers/partners.

  • Plan and participate in subsystem integration and verification, including testing.

  • Organize and conduct subsystem design reviews and deliver subsystem contributions to system-level design reviews.

  • Help to develop and implement company systems engineering standards and practices, in collaboration with the other members of the systems engineering community and cross-discipline SMEs.

You Must Have:

  • Minimum bachelor’s degree

  • Minimum 6+ years of professional experience (4 years with masters, 3 years with PhD) in a combination of systems engineering roles and design, integration, or testing roles, where the system of interest is based on optical, laser, and/or photonics technologies. Minimum 2 years of this experience must be in a systems engineering role.

    • Candidates with more years of experience than these minimums may be considered for a higher-seniority/Lead position.

  • 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, or worker granted asylum or refugee status

We Value:

  • Bachelor’s degree in engineering, physics, or a closely-related technical field preferred.

  • Experience in systems engineering or architecture of highly complex, large-scale technologies (e.g., quantum computers, atomic clocks, spacecraft, semiconductor manufacturing equipment, or other multidisciplinary hardware systems).

  • Expertise in one or more of the following technology areas: fiber optics and connectors for visible wavelengths, single-photon detectors and systems, micro-optic assemblies, free-space laser metrology, optical frequency combs, laser stabilization and locking, laser and optical system design, optomechanical design, qualification and reliability modelling and/or testing of optical components.

  • Experience with formal documentation and management of requirements, interfaces, verification plans, and other systems engineering artifacts in database and/or product lifecycle management tools.

  • Strong communication, leadership, and partnership skills.

  • Prior experience with laser-cooled, neutral atom, or atomic ion scientific apparatus or quantum computers.
