Senior Electronics Design Engineer in Cambridge

Filtronic is seeking a highly skilled Electronics Engineer to support and lead the design of radio frequency products with responsibility for analogue and digital circuit design and schematic capture, ensuring that electrical performance, quality, cost and manufacturability requirements are met.

You will work on innovative RF and communications products from concept through to volume manufacture, contributing to telecoms, space, high‐altitude platforms, and defence systems. This role offers the opportunity to work in a multidisciplinary environment alongside RF, FPGA and systems engineers, using modern development tools and cutting‐edge technology.

Purpose of RoleThe role is to lead the specification, design, development and verification of advanced analogue and digital electronic circuits that enable high‐performance telecommunications, satellite and defence products. Working closely with our RF engineering team and cross‐functional hardware, software and firmware groups, you will create robust mixed‐signal solutions that integrate seamlessly into complex system architectures.

You will be responsible for the end‐to‐end design of digital and analogue circuitry, including high‐speed digital systems utilising FPGAs, microprocessors, ADCs, DACs and associated glue logic; low‐voltage power supply modules; component bias networks; and analogue signal‐conditioning elements such as filters and amplifiers. This includes detailed component selection, simulation, schematic capture, PCB requirements definition and the delivery of fully verified, documented designs that meet strict technical, schedule and cost targets.

The role also covers working with modern high‐speed digital interface standards (PCIe, USB, Ethernet, CAN bus, I2C, SPI, etc.), ensuring compatibility and performance; resolving hardware and communication issues; performing system‐level integration and testing; and supporting reliability processes including thermal analysis, MTBF, component derating and tolerance assessments.

You will contribute to design reviews, manage component obsolescence and support product introduction through problem‐solving, fault diagnosis and the preparation of diagnostic procedures. By staying current with industry trends and emerging standards, you will ensure our products remain innovative, reliable and competitive.
