Associate Electrical Engineer at Infleqtion in Boulder, CO

At Infleqtion we solve the world’s most challenging problems using cutting-edge quantum technology. Our mission is to commercialize atom-based quantum products that provide orders of magnitude improvements in sensing and computing applications. We are proud to work tirelessly to create and lead the quantum ecosystem towards meaningful advancements today and set the technology roadmap for tomorrow.

POSITION SUMMARY

Within Infleqtion’s Quantum Computing Product Group, the Hardware Engineering Team is seeking an Associate Electrical Engineer to help develop the electronics that power next‑generation neutral‑atom quantum computing platforms.

This role is ideal for an engineer who enjoys hands-on hardware development. You will work directly with engineers and physicists to design small PCBs, build prototype electronics, debug experimental systems, and support hardware bring-up.

JOB RESPONSIBILITIES

Typically, you will be entrusted with:

• Design small analog and mixed-signal circuits used for instrumentation, control electronics, and laboratory hardware.
• Develop and maintain PCB designs for prototype and experimental systems.
• Bring up and debug new electronics hardware, including power supplies, RF subsystems, and digital control electronics.
• Perform laboratory testing and measurements using oscilloscopes, spectrum analyzers, VNAs, multimeters, and signal generators.

• Support integration of electronics into optical, mechanical, and experimental physics systems.
• Assist senior engineers with hardware architecture, component selection, and prototype development.
• Build and modify experimental hardware including wiring harnesses, test fixtures, and lab instrumentation setups.
• Document designs, schematics, test results, and debugging procedures.
