Tech Stack

About the role

  • Leading the design, modeling, and validation of complex optical and laser-based subsystems supporting neutral-atom quantum computing.
  • Developing and integrating scalable atom addressing and control technologies. This includes but is not limited to digital micromirror devices (DMDs), spatial light modulators (SLMs), acousto-optic deflectors (AODs), electro-optic modulators (EOMs), metasurface-based optics, and fast multi-beam steering architectures.
  • Designing and implementing (at a subsystem level) atom-resolved detection and feedback systems using state-of-the-art sensors such as SPAD/EMCCD/sCMOS cameras, and high-speed photodetectors, with consideration for scaling readout bandwidth, latency, and data throughput.
  • Collaborating closely with physicists and optical, mechanical, electrical, software, and systems engineers to support the full experimental and hardware development lifecycle, from early research demonstrations to integrated, scalable systems.
  • Leading hands-on laboratory efforts, including optical assembly, precision alignment, debugging, and performance characterization of complex, multi-channel optical systems.
  • Developing and maintaining high-fidelity optical models using Zemax (OpticStudio), including tolerance analysis, sensitivity studies, and performance optimization informed by experimental data and system-level requirements.
  • Defining and executing experimental strategies to characterize optical stability, drift, noise sources, and scaling limits, and using those results to inform design tradeoffs.
  • Leading the transition within a defined architecture of optical subsystems from research-grade configurations to repeatable, maintainable, and scalable hardware suitable for larger atom counts.
  • Providing direct management, technical guidance, and mentorship to optical engineers through design reviews, hands-on coaching, and professional development.
  • Establishing and improving best practices for optical design workflows, laboratory procedures, documentation, and version control.
  • Supporting technical troubleshooting and cross-functional design reviews as needed to resolve complex system-level issues.

Requirements

  • Bachelor’s degree in optical engineering, physics, or a related field with at least 6 years of relevant industry experience. Master’s degree or PhD may substitute for some experience.
  • Strong experience designing, modeling, and validating laser-based, atomic, or quantum optics systems.
  • Hands-on laboratory expertise in precision optical alignment and experimental troubleshooting.
  • Proficiency with Zemax (OpticStudio) for optical system design and tolerance analysis.
  • Working knowledge of SolidWorks sufficient to collaborate on opto-mechanical layouts and interfaces.
  • Experience using git or similar version control systems for design artifacts, scripts, or analysis tools.
  • Experience mentoring or technically leading engineers in a research or hardware-focused environment.
  • **WE HIGHLY VALUE:**
  • Background in atomic physics, quantum optics, or photonics research environments.
  • Experience working with stability-sensitive optical systems subject to thermal, vibrational, or long-term drift effects.
  • Strong verbal and written communication skills, with the ability to bridge physics and engineering perspectives.
  • A hands-on, detail-oriented mindset with a strong sense of ownership and technical accountability.
  • Positive, collaborative working style and enthusiasm for mentoring and developing engineers.
