At Atom Computing, we build quantum computers using arrays of optically trapped neutral atoms that will empower customers to achieve unprecedented computational breakthroughs. Join a world-class team of scientists, engineers, and business professionals to advance the state-of-the-art in quantum computing. We are seeking a Senior System Integration & Test Engineer to integrate verified subsystems and align the complete optical system of neutral-atom quantum computers. This hands-on role performs system-level checkout without atoms, delivering the alignment and configuration records Quantum Engineers (QEs) need to begin atom-based testing. RESPONSIBILITIES * Install released optical, laser-delivery, mechanical, and electronic assemblies; verify mounting, connections, and interfaces against the approved system configuration. * Align optical paths between subsystems, including beam-delivery and imaging interfaces; establish specified beam geometry, polarization, and coupling without atoms. * Connect fibers and radio-frequency (RF)/control cabling while preserving cleanliness and mechanical stability; coordinate laser-delivery and control-channel checks with specialists. * Measure system optical throughput, beam quality, and alignment stability using approved diagnostics and metrology; compare results against QE-approved handoff criteria. * Diagnose cross-subsystem alignment and interface problems with laser, controls, and subsystem engineers; isolate the cause and implement only approved corrections. * Complete assigned controls, safety, and readiness checks; maintain safe laser-laboratory practices throughout integration. * Record alignment measurements, system configuration, completed work, and open issues in the SI&T handoff package. * Work alongside QEs during first-of-a-kind integration to capture installation sequences, alignment references, and diagnostic methods for repeat builds. * Support hardware corrections during QE testing while preserving the approved configuration; QEs retain circuit validation and technical acceptance. * Improve integration instructions and alignment methods alongside Manufacturing Engineering. EXPERIENCE & EDUCATION Bachelors in physics, optical engineering, electrical engineering, mechanical engineering, or a related field, or equivalent integration experience; MS preferred 5+ years of hands-on integration and alignment of precision laser, optical, or atomic-physics systems involving multiple interacting subsystems Experience establishing complete-system readiness from optical measurements, interface checkout, fault isolation, and controlled configuration records. Experience integrating quantum-computing or atomic, molecular, and optical (AMO) laboratory hardware preferred, including collaboration with experimental physicists. QUALIFICATIONS Strong hands-on free-space alignment, fiber coupling, polarization control, and end-to-end optical troubleshooting skills. Working understanding of neutral-atom hardware functions such as trapping, optical addressing, and imaging, and their implications for system alignment. Ability to interpret optical layouts, mechanical references, electrical connections, and interface-control documentation across subsystem boundaries. Experience with optical power meters, beam cameras, and related diagnostics; familiarity with RF/control interfaces and laboratory scripting preferred. Precise alignment and checkout records, safe laser-laboratory practices, and clear communication with quantum physicists and specialist integration engineers. Atom Computing provides a wide variety of perks and benefits, including fully paid medical, dental, and vision insurance for our employees and their dependents. Additionally, unlimited paid time off, 401K company matching, short- and long-term disability, FSA, dependent care benefits, and life insurance. We also offer drinks, snacks, and catered team lunches in our offices, every day! The base salary range for this position is between $170,000 - $200,000, commensurate with experience. In addition to salary, we offer an annual bonus and equity in the company.
