Job Summary

Infleqtion UK is looking for an Embedded Systems Engineer with a passion for working with a multi-disciplinary team to bring state-of-the art quantum technologies outside the laboratory and into the real-world. You will use your analytical and problem-solving skills to contribute to the design, implementation, and operation of atom-based quantum technologies, such as inertial navigation systems, radiofrequency sensors, and atomic clocks.

Job Responsibilities

The duties and responsibilities outlined below include essential functions of the role. Depending on business needs, this role may perform a combination of some or all of the following duties. Duties, responsibilities, and activities may change, or new ones may be assigned at any time with or without notice.

• Work collaboratively with a multidisciplinary team to coordinate the productisation of atom-based quantum technologies, such as atomic clocks and inertial sensing systems
• Develop electronics and microsystems solutions required to control atomic clock subsystems, including laser and frequency comb drivers, amplifiers, various types of photodetectors (such as photomultipliers and photodiodes), thermal sensors, heaters, and coolers, and RF upconversion/downcoversion
• Design, develop, and program circuits that enable I/O control between subsystems and enable power distribution to across subsystems
• Measure and resolve sources of noise
• Select and/or develop and implement control algorithms in firmware as necessary
