Quantum Software Engineer - QEC

Infleqtion is a global quantum technology company solving the world’s most challenging problems. The company harnesses quantum mechanics to build and integrate quantum computers, sensors, and networks. From fundamental physics to leading edge commercial products, Infleqtion enables “quantum everywhere” through our ecosystem of devices and platforms. Our mission is to commercialise atom-based quantum products that provide orders of magnitude improvements in performance and computing applications.

Infleqtion is seeking a Quantum Error Correction Specialist to design, analyse, and implement fault-tolerant architectures that enable scalable, high-fidelity quantum computation. In this role, you will develop and evaluate error-correcting codes, decoding algorithms, and fault-tolerant gate constructions tailored to our hardware platforms, translating theoretical QEC frameworks into experimentally realizable protocols. You will work closely with hardware, control, and compiler teams to model noise processes, optimize syndrome extraction and decoding performance, and define logical performance metrics that inform system design. The ideal candidate brings deep expertise in quantum information theory and fault tolerance, strong analytical and simulation skills, and the ability to bridge theory and implementation to advance the reliability and scalability of next-generation quantum systems.
