FPGA & DSP Engineer (Quantum RF)

ABOUT THE COMPANY

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.

LOCATION

Infleqtion has offices in the USA, United Kingdom and Australia. This is a full-time position in our Kidlington, Oxford office. Our flexible working policy enables all full-time employees to work up to 2 days a week from home as work permits. 

POSITION SUMMARY

Infleqtion UK is in search of a highly motivated Control Systems Engineer with FPGA and DSP experience, and with a keen interest in joining a diverse, interdisciplinary team dedicated to transcending the boundaries of quantum technology, bringing it from the confines of the laboratory into practical real-world applications. As a Control Systems Engineer, you will employ your analytical and problem-solving skills to contribute to the design, implementation, and operation of atom-based quantum technologies, primarily on quantum RF sensors, but also encompassing inertial navigation systems 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.

• Collaborate seamlessly with a multidisciplinary team to orchestrate the development of atom-based quantum technologies, with a focus on quantum RF sensors and atomic clocks.
• Engineer electronic solutions tailored for controlling subsystems, such as laser and optical frequency comb drivers, optical and electronic amplifiers, photodetectors, thermal sensors, and RF signal chains.
• Implement real-time and pipelined digital signal processing (DSP) algorithms on high-speed signals within an FPGA including FIR/IIR filters, I/Q frequency mixers, and similar.
• Writing automated test benches to verify designs.
• Debug of complex embedded systems comprising hardware, software (processor) and firmware (FPGA) designs.
• Create high speed interfaces from FPGA to hardware peripherals such as ADCs, DACs, DDS, PLL and other devices.
• Execute high-speed feedback control systems (PID and similar) on an FPGA.
• Collaborate closely with software, electronics and systems engineers to design and realise new FPGA-based peripherals.
• Employ precision test and measurement equipment to characterize and test systems.
• Conduct critical design reviews based on product specifications.
• Create, document, and maintain designs and architectural blueprints.
• Effectively manage technical priorities, meet deadlines, and deliver on project objectives.
