This role is responsible for the design, implementation, verification and maintenance of FPGA logic for controller boards supporting optical switching products. You will play a key role in developing reliable FPGA solutions using VHDL on Xilinx Artix-7 devices, supporting the full development lifecycle from initial design through to hardware validation and production release.
Key Responsibilities:
* Design, implement and maintain FPGA logic in VHDL for Xilinx Artix-7 devices using Vivado, ensuring adherence to coding standards and best practices.
* Develop deterministic finite state machines (FSMs) to control and sequence hardware interfaces and embedded protocols.
* Design and validate low-level driver logic for interfaces including I²C and SPI, with UART and other serial interfaces where required.
* Create and maintain self-checking test benches, perform functional and timing simulations, and document verification activities.
* Carry out FPGA hardware bring-up, testing and validation using laboratory equipment including logic analysers and oscilloscopes.
* Develop and maintain timing constraints (XDC), manage clocking strategies, resets and clock domain crossing (CDC) considerations, achieving timing closure for production-ready designs.
* Support system integration by working closely with electronics and embedded software engineers.
* Produce high-quality technical documentation including design specifications, interface documentation, verification reports and release notes.
* Participate in design reviews, code reviews and continuous improvement initiatives relating to FPGA development processes and automation.
* Maintain FPGA source code and releases using version control systems, ensuring traceability throughout the development lifecycle.
The ideal candidate must have:
* Degree (or equivalent experience) in Electronic Engineering, Electrical Engineering, Computer Engineering or a related discipline.
* Strong commercial experience developing FPGA solutions using VHDL.
* Proven experience targeting Xilinx Artix-7 FPGA devices.
* Confident user of Xilinx Vivado including synthesis, implementation, timing analysis, place & route and bitstream generation.
* Strong understanding of finite state machine (FSM) design.
* Experience implementing and validating low-level communication interfaces including I²C and SPI.
* Experience writing self-checking test benches and carrying out FPGA simulation.
* Practical hardware debugging experience using laboratory test equipment.
* Strong understanding of timing constraints (XDC), synchronous design principles, clock domain crossing (CDC), metastability and reset strategies.
* Experience using version control systems such as SVN.
