Embedded Systems Engineer - FPGA Platform

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.

Location

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

Position Summary

As part of our UK growth strategy, we are expanding our Engineering Team and recruiting anEmbedded Systems Engineer to support our Quantum RF (QRF) and sensing projects.

In this role, you will develop the embedded control, acquisition, timing, and communications systems that underpin quantum-enabled RF sensors and deployable sensing products. You will work closely with physicists, electronics, FPGA, systems, and software engineers to take designs from requirements through implementation, characterisation, integration, and deployment.

Job Responsibilities

Technical

• Develop embedded Linux software, firmware, and board-support packages for FPGA-based embedded systems, particularly Xilinx FPGA SoC platforms, using C/C++, Rust, and related tools.
• Develop and deploy embedded Linux distributions using Yocto, Buildroot, or similar tools.
• Develop device-tree configurations, low-level drivers and hardware interfaces for FPGA peripherals, sensors, communications devices, and microcontroller subsystems.
• Integrate FPGA SoC platforms, microcontrollers, electronics, and higher-level software into robust control, acquisition, timing, signal-processing, and communications systems.
• Perform board bring-up, hardware–firmware integration, automated test, debugging, and validation using Python and benchtop test equipment.
• Produce reliable, maintainable software and clear technical documentation, supporting products from prototype through deployment and maintenance.

Personal and Team Responsibilities

• Collaborate effectively with team members to ensure technical objectives and deadlines are met.
• Work within multidisciplinary teams of software engineers, electronics engineers, physicists and technicians.
• Communicate technical risks, findings and design decisions clearly.
• Adapt to changing requirements and manage technical ambiguity effectively.
• Take ownership of assigned work from requirements definition through implementation, testing and delivery.
