Atom Computing is building quantum computers using arrays of optically trapped neutral atoms. We seek a Senior System Integration & Test Engineer to integrate verified subsystems and align the complete optical system of neutral-atom quantum computers. In this hands-on role, you will perform system-level checkout without atoms, delivering alignment and configuration records that Quantum Engineers need to begin atom-based testing. You will install released optical, laser-delivery, mechanical, and electronic assemblies; verify mounting, connections, and interfaces against approved system configuration. You will align optical paths between subsystems, including beam-delivery and imaging interfaces, establishing specified beam geometry, polarization, and coupling without atoms. Key responsibilities include connecting fibers and RF/control cabling while preserving cleanliness and mechanical stability; measuring system optical throughput, beam quality, and alignment stability using approved diagnostics and metrology; diagnosing cross-subsystem alignment and interface problems with laser, controls, and subsystem engineers; and completing assigned controls, safety, and readiness checks. You will record alignment measurements, system configuration, completed work, and open issues in the SI&T handoff package, and work alongside Quantum Engineers during first-of-a-kind integration to capture installation sequences, alignment references, and diagnostic methods for repeat builds. You will support hardware corrections during QE testing while preserving the approved configuration, and collaborate with Manufacturing Engineering to improve integration instructions and alignment methods. REQUIREMENTS: - Bachelor's degree in physics, optical engineering, electrical engineering, mechanical engineering, or related field (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 - 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 - Experience integrating quantum-computing or atomic, molecular, and optical (AMO) laboratory hardware preferred, including collaboration with experimental physicists
