FPGA Engineer / Senior FPGA Engineer - Power Supplies

Diamond Light Source is the UK's national synchrotron, serving scientists and researchers from around the world. It is a not-for-profit joint venture, providing academic and industry researchers access to facilities that enable world-changing science.

The machine generates extremely bright light that is directed into laboratories known as beamlines. Scientists use the light to find solutions to humanity's most critical challenges, from health, food security and biotechnology to energy, climate change and advanced materials.

Diamond is in the process of upgrading to a fourth-generation synchrotron, generating a brighter and more coherent light. This will provide enhanced imaging and analysis capabilities, helping the UK to remain at the forefront of scientific discovery.

About the Role We now have an opportunity for a FPGA Engineer or Senor FPGA Engineer to join our team, for a 3-year fixed term contract, in developing FPGA firmware for the next generation of power supplies for the Diamond-II upgrade project, focusing on quality, reliability, and stability Applicants will be considered at either FPGA Engineer or Senor FPGA Engineer level, depending on the strength of your skills, experience and qualifications.

Key Responsibilities

Develop, maintain, and debug HDL code for Xilinx FPGAs in Vivado, implementing full-cycle firmware for Diamond magnet power supplies, including feedback control, filtering, and interlock handling using state machines. Design and integrate interfaces to peripherals such as ADCs, DACs, SRAM, Flash memory, sensors, and microcontrollers.

Test and verify FPGA designs through simulation test benches and on-hardware validation using logic analysers. Collaborate with hardware engineers and the Control Group to optimise performance, resolve issues, and develop reliable Ethernet-based control interfaces.

Review, refactor, and document HDL code in line with Diamond standards, ensuring proper version control and maintainability. Contribute to electronic circuit design, simulation (SPICE, MATLAB), PCB design, and prototype testing to support FPGA-based control system development.

As a Senior FPGA Engineer you will also: Lead the development, maintenance, and debugging of HDL code for FPGA (Xilinx)-based controllers, including full-cycle implementation of: DLS Magnet power supplies' controllers State machines, signal conditioning algorithms (e.g., filters) Interfaces to memories, digital and analog sensors, DACs, ADCs, and other peripherals.

Interfaces to control and monitoring GUIs developed by Control Group via ethernet. Lead the review and enhancement of legacy code to align with Diamond standards. About You You will hold an appropriate Engineering or Science degree (Bache...
