Senior Optical Engineer – Quantum Networking Group

We are looking for an Optical Engineer to join our Quantum Networking Group. As an Optical Engineer, you will design, prototype, and validate advanced optical systems for quantum networking, specifically focusing on the development of high‑fidelity Bell State Analyzers and quantum state tomography modules.

• Design and simulate complex free‑space and fiber‑optic assemblies for quantum interference and entanglement distribution.
• Develop and characterize Bell State Analyzers (BSA) using high‑efficiency single‑photon detectors and precise temporal/spatial overlap control.
• Implement automated quantum tomography protocols to characterize the fidelity of networked quantum states.
• Collaborate with the systems engineering team to integrate optical networking hardware into the broader IonQ quantum computer architecture.
• Execute rigorous experimental validation of optical components, including polarization extinction ratios, insertion losses, and interferometric stability.
• Optimize optical alignment procedures to transition laboratory‑grade setups into robust, field‑deployable quantum networking equipment.

• 5+ years of professional experience in Optical Engineering, Photonics, or Applied Physics with a focus on precision optical systems.
• Master’s degree in Optical Sciences, Physics, Electrical Engineering, or equivalent practical experience.
• Proficiency in data analysis (e.g., Python) and instrument control (e.g., Lab View, Simulink).
• Hands‑on experience with ultra‑stable interferometry, fiber optics, and precision alignment of free‑space optical systems.
• Deep understanding of photon statistics and single‑photon detection technologies (SNSPDs, APDs).
• Strong analytical skills and ability to troubleshoot complex electro‑optical systems in a fast‑paced environment.

• Ph.D. in Physics or Optical Engineering with a thesis focused on Quantum Optics or Quantum Information Science.
• Proficiency in optical design software (e.g., Zemax, Code V, or Lumerical).
• Experience with Hong‑Ou‑Mandel interference and entanglement swapping protocols.
• Familiarity with FPGA‑based time‑tagging and coincidence counting electronics.
• Knowledge of laser frequency stabilization techniques and nonlinear optics (e.g., SPDC, frequency conversion).
• Experience with PICs.

The approximate base salary range for this position is $114,750 – $150,237. Total compensation includes base, bonus, equity, and benefit options as detailed on our career site.

Medical, dental, and vision plans; matching 401(k); unlimited PTO and paid holidays; parental/adoption leave; legal insurance; home‑technology stipend.
