Senior Printed Circuit Board Designer, Bristol

Overview

We are seeking experienced PCB Design Engineers to join a fast-growing advanced hardware engineering environment, developing next-generation high-performance compute platforms. This role will focus on the design and development of complex, high-speed digital boards supporting extremely demanding bandwidth, signal integrity, and power delivery requirements. The successful candidate will work closely with hardware, SI/PI, systems, and manufacturing teams across the full product lifecycle from concept through production.

The work involves advanced board architecture and high-speed interconnect challenges associated with modern AI compute, accelerator, networking, and HPC-class systems.

Key Responsibilities

• Design and develop complex high-speed multilayer PCBs for advanced systems
• Work on PCIe Gen6 and other ultra-high-speed serial interfaces
• Develop PCB layouts with strong consideration for SI/PI, EMC, manufacturability, and thermal performance
• Collaborate with hardware engineers, SI/PI engineers, mechanical teams, and manufacturing partners
• Support schematic capture, floor planning, placement, routing, stack-up definition, and constraint management
• Drive board designs from early architecture through prototype, validation, and production
• Support debugging and bring-up activities where required
• Work closely with external fabrication and assembly vendors
• Contribute to design reviews and engineering process improvements

Required Experience

• Strong experience in high-speed digital PCB design
• Experience with PCIe, SerDes, DDR, Ethernet, or other high-speed interfaces
• Strong Cadence Xpedition/Expedition experience
• Experience designing complex multilayer PCBs
• Understanding of signal integrity and power integrity fundamentals
• Experience with controlled impedance and high-speed routing constraints
• Experience taking hardware designs through full product lifecycle
• Ability to work within a fast-moving engineering environment

Desirable Experience

• PCIe Gen5/Gen6 experience
• AI accelerator, networking, HPC, datacentre, telecoms, or server hardware experience
• Exposure to SI/PI simulation tools
• Knowledge of high-current PDN design
• Experience with manufacturing and DFM/DFT processes
• Familiarity with compliance and EMC considerations
• Experience supporting board bring-up and hardware validation
