Job Description

Infleqtion is at the forefront of the rapidly evolving quantum systems industry, pioneering the commercialization of Quantum Systems using Neutral Atoms - nature’s perfect sensors and qubits. This exciting field is poised for groundbreaking advancements, and we are driving innovative developments such as Optical Atomic Clock product, ‘Tiqker,’ Quantum Computing system, ‘Sqale,’ and advanced Quantum-RF and Quantum-Inertial sensing systems.

Our future quantum products will depend on CMOS foundry-based Silicon Photonics PICs for miniaturization, high-volume low-cost manufacturing, reliability, and ruggedization. These PIC-based devices and systems will revolutionize the industry by replacing the large and expensive lab-quality laser systems, precise frequency control, and atom-addressing methods currently used in quantum systems. To meet this vital requirement, we are expanding our integrated photonics team and seeking experienced engineers with hands-on skills in designing and testing Silicon Photonics PIC-based lasers and laser system components. Join us in shaping the future of quantum technology and creating products that will transform the world.

We seek an exceptional candidate with extensive experience in integrated photonics technologies, devices, and applications. This individual will play a crucial role as a founding member in the integrated photonics team at Infleqtion. The integrated photonics team will work directly with each quantum systems team to identify PIC opportunities and develop PIC based devices for use in prototype quantum systems. Additionally, the team will collaborate with suppliers and manufacturing partners to provide qualified PIC based devices for Infleqtion products.
