Senior Optical Engineer

Role SummaryThe Senior Optical Engineer owns the optical engine of Photon Queue's quantum memory platform. In this role you will take end-to-end ownership of the optical system design from customer and system requirements through to the final product. Working within a cross-functional team, you will develop the full 3D optical layout, formulate alignment strategies, build optical performance models, perform stray light, sensitivity, and tolerance analyses, prescribe component specifications, and qualify hardware performance. As the technical authority on everything light touches in the system, your designs set the performance floor that everything else is built around. Location: On-site, Chicago areaCandidates must have current US work authorization - we are unable to sponsor visas at this time.We are an in-office company, and our expectation is that employees primarily work from their Photon Queue office 5 days a week. However, we also recognize the importance of flexibility and trust our employees to manage their schedules responsibly. This may include occasional remote work, starting the day with morning meetings from home before heading to the office, or leaving earlier when needed to accommodate family commitments.ResponsibilitiesConcept DevelopmentTranslate system-level and customer requirements into detailed optical requirements, and run trade studies on competing optical architectures to guide early design decisionsAssess feasibility of new concepts and articulate design trade-offs to engineering leadership and cross-functional partnersDetailed Design & AnalysisOwn the optical prescription end-to-end design the free-space reflection cell, prescribe mode-matching optics, set the optical path geometry between elements, and design the active alignment systems that hold the system in specBuild and own the optical performance models that predict and optimize the system's key figures of merit optical delay, throughput, and beam quality using Gaussian beam, polarization, and stray light analysisRun sensitivity analyses and build the optical error budget, flowing tolerances down to individual elements and assemblies to drive the mechanical designSpecify every optical component substrate, coatings, surface figure, surface roughness, and surface quality and translate those specifications into drawings for fabricationSoftware & ToolingDevelop both scripted and agentic Python workflows that automate optical layout generation and CAD integration to accelerate design iterationScript and automate optical simulations and analysesPrototyping, Testing & ManufacturingBuild and characterize optical hardware using optical metrology to validate performance against system requirements and model predictionsDesign and build optical test stations and benches for engineering and production testingTranslate the alignment strategy into repeatable alignment methods, acceptance tests, and work instructions that transfer the design reliably into productionExecution & DeliveryIdentify, select, and manage optical vendors; lead DFM discussions to ensure designs are manufacturable and meet performance targetsLead optical design reviews and own the supporting documentation - specifications, drawings, and test plansSupport field failure analysis and re-alignment for deployed systemsQualificationsMinimum qualificationsM.S. or higher in Optical Engineering, Physics, EE, or a related field (or a B.S. with additional experience), plus 5+ years of optical system design through the complete product lifecycle; a Ph.D. may count toward the experienceHigh proficiency in optical design and analysis software (FRED, LightTools, Zemax or similar) and in Python for simulation, analysis automation, and lab test softwareStrong grounding in physical optics and Gaussian beam propagation, with hands-on experience in optical metrology (flatness, roughness, wavefront and beam quality), sensitivity analysis, and error budgetsStrong communication skills able to lead design reviews and collaborate across engineering disciplinesPreferred qualificationsFamiliarity with CAD, GD&T and with optical fabrication processesExperience with optical alignment techniquesFamiliarity with free-space optical, laser, quantum, or photonic systemsFamiliarity with automated and agentic workflow developmentComfortable or excited to work in a startup or fast-paced environmentWe encourage you to apply even if you dont meet all of the qualifications stated above.
