Location

This position is a full-time position and is based in our Oxford, England office.

POSITION SUMMARY:

Infleqtion UK is in search of a highly motivated FPGA Engineer 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, including 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.

• Collaborate seamlessly with a multidisciplinary team to orchestrate the development of atom-based quantum technologies, encompassing atomic clocks and inertial sensing systems
• Engineer electronic and microsystem solutions tailored for controlling subsystems, such as laser and frequency comb drivers, amplifiers, various photodetectors (e.g., photomultipliers and photodiodes), thermal sensors, heaters, coolers, and RF upconversion/downconversion
• Implement digital transmit/receive (TX/RX) and real-time digital signal processing (DSP) functions on an FPGA
• Create high speed interfaces from FPGA to peripherals such as ADC, DAC, DDA, PLL and other high-speed devices
• Execute high-speed DSP in the loop feedback control systems on an FPGA
• Collaborate closely with electronics and systems engineers to design and realize FPGA-based peripherals
• Employ precision test and measurement equipment to characterize and test systems
• Conduct critical design reviews based on specific product specifications
• Create, document, and maintain electronic designs and architectural blueprints
• Effectively manage technical priorities, meet deadlines, and deliver on project objectives
