Senior PCB CAD Engineer – Reading (On-site)

At Sequans, we know that our success depends on our people, so we are always on the lookout for innovators, leaders, and visionaries. Our team is driven by a shared desire to lead in the IoT semiconductor and to push the limits of technology development. From thumbnail-sized cellular modules to large evaluation boards, every chip we design needs a board that does it justice. We are looking for a senior PCB CAD Designer who loves the craft of layout, dense multilayer stack-ups, RF up to 8 GHz, clean power and fast digital routing, and wants to own the full journey from concept schematic to manufactured board. ROLE: As our go-to expert for PCB CAD and Altium, you will lead board design for the Hardware Platform team and look after our Altium Workspace libraries. You will work side by side with hardware, RF and simulation engineers, influence design choices early, and see your boards through to manufacturing. It is a hands-on, high-ownership role where your expertise directly shapes the quality of our products. RESPONSIBILITIES: Design Own PCB CAD design for characterisation and evaluation boards: schematic capture, concept placement and layout, from specification to release Tackle demanding designs: multilayer modules and boards with RF, EMC, high-speed digital, power supply and thermal constraints Act as the technical reference for PCB technologies, host board and module design rules, and advise engineers on the best trade-offs Review requirements with hardware engineers and work closely with simulation engineers Design the mechanical side too: 3D models, stencils, module holders, metal plates, shields and heatsinks Libraries
