Senior Photonics Design, Layout & Modeling Engineer

About the Team

Infleqtion is commercializing quantum technology, building deployable systems where photonics is the engine for performance, scale, and reliability. Our photonics team develops integrated photonics (PICs) and related optical subsystems that enable chip-scale laser sources, modulation, routing, and control for next-generation quantum products. We work closely with quantum system teams, and external foundry/assembly partners to turn ambitious optical performance targets into manufacturable hardware.

About the Role

Infleqtion is seeking a Senior Photonics Design, Layout & Modeling Engineer to design and deliver next-generation photonic integrated circuits and photonic subassemblies, with an emphasis on simulation-driven design, layout/verification, and rapid experimental feedback.

In this role, you will own portions of PIC design from concept through tapeout and test—translating system requirements into photon...
