RF Design Engineer

The role

Overview

Expleo Defence is seeking an experienced RF Design Engineer to join our growing engineering team, supporting the design, development and validation of advanced RF and mixed-signal electronics for defence and high-technology applications.

What you will do

Design and develop RF analogue and mixed-signal electronics for complex engineering systems.
Design RF transceiver and front-end architectures using monolithic RF chipsets, including MMIC, SiP and SoC-style devices.
Develop RF schematics, component selections and circuit designs in accordance with system requirements.
Design and implement RF impedance matching networks, including L/C matching and other appropriate techniques.
Translate RF component datasheets, application circuits, biasing requirements and recommended matching networks into robust designs.
Work closely with PCB layout engineers to ensure RF designs are implemented correctly, considering signal integrity, grounding, shielding, routing and manufacturability.
Integrate RF blocks and sub-systems into larger electronic and system architectures.
Develop and execute RF design verification and validation activities.
Conduct hands-on laboratory testing using equipment such as:
Spectrum analysers.
Vector Network Analysers (VNAs)
RF signal generators.
Power meters.
Oscilloscopes and associated RF test equipment.
Analyse measured data and use results to troubleshoot and improve RF designs.
Investigate RF performance issues and systematically debug problems across hardware, layout and system interfaces.
Produce clear and traceable engineering documentation, including:
Schematics.
Design calculations.
Design notes.
Test plans.
Test procedures.
Verification and validation reports.
Test results.
Collaborate with test and validation teams to ensure designs meet specified performance requirements.
Work with firmware/software engineers where required to support RF device configuration, control and system integration.
Support design reviews, technical investigations and engineering problem-solving activities.
Contribute to the development of engineering processes, standards and best practice within the wider Expleo team.

Essential skills

The successful candidate will have

Solid knowledge of RF principles, including:
Signal propagation
RF link budgets
Noise
Dynamic range
Gain and attenuation
Filtering
RF performance metrics
Basic RF regulations and compliance considerations
Ability to interpret RF test results and use measured data to identify and resolve design issues.
Ability to interpret RF component datasheets and translate manufacturer recommendations into practical circuit designs.
Strong problem-solving and debugging capability, with the ability to iterate RF designs based on laboratory measurements.
Knowledge of relevant RF design standards and regulatory requirements.

What you need

We are looking for a hands-on RF Design Engineer who can combine strong theoretical RF knowledge with practical design and laboratory experience.

You should be comfortable working independently on RF design problems, but equally capable of collaborating with multidisciplinary engineering teams. The ideal candidate will be someone who enjoys getting into the laboratory, measuring real hardware, understanding why a design is not performing as expected and iterating the design to achieve the required performance.

This role would suit an experienced RF Engineer, RF Design Engineer, RF Electronics Engineer or Electronics Design Engineer with significant RF experience.

Recent experience using RF simulation and modelling tools, particularly:
- CST
Ansys HFSS
Experience within the defence, aerospace, telecommunications or other high-reliability engineering sectors.
Experience with RF systems operating in challenging or safety-critical environments.
Experience taking RF designs through development, verification and into production.
Proven experience designing and validating RF analogue and mixed-signal electronics.
Hands-on experience designing RF transceivers using monolithic chipsets, such as MMIC, SiP or SoC-style RF devices.
Demonstrable experience with RF impedance matching, including L/C matching and matching networks.
Experience producing detailed electronic schematics and working effectively with PCB layout engineers.
Practical experience validating RF designs within a laboratory environment.
Experience using common RF test equipment, including spectrum analysers, VNAs, signal generators and RF power measurement equipment.
Experience integrating individual RF blocks into a larger electronic or system-level architecture.
Experience working collaboratively with RF/electronics engineers, PCB layout engineers, test and validation teams and firmware/software engineers.
Strong technical documentation skills, with experience producing clear and traceable engineering documentation.
