Senior Advanced Wireless/ RF Engineer

Senior Advanced Wireless / RF Engineer - Aerospace & Space Communications

Design and develop advanced RF technologies for next-generation communication systems.

We are seeking an experienced Senior Advanced Wireless / RF Engineer to join an innovative engineering team, contributing to the design, development, integration and qualification of advanced radio frequency (RF) hardware for mission-critical communication systems.

This is an exciting opportunity for a highly skilled RF engineer with strong hands-on experience in microwave hardware development, active RF circuit design and system-level analysis. You will work across a broad frequency range, from UHF to Ka Band, supporting telemetry, telecommand and satellite datalink applications.

The successful candidate will take technical ownership of complex RF engineering activities, working closely with multidisciplinary engineering teams, product owners, project engineers and customers to deliver high-performance, reliable communication solutions.

Key Responsibilities

Design and develop RF hardware for communication systems operating from UHF to Ka Band, supporting telemetry, telecommand and datalink applications.

Design and develop active RF circuits, including Low Noise Amplifiers (LNAs), Solid State Power Amplifiers (SSPAs), driver amplifiers, mixers, frequency converters, frequency synthesizers and Phase-Locked Loops (PLLs).

Perform RF architecture trade-offs, link budget calculations, RF line-up analysis, gain and noise analysis, linearity assessments and dynamic range calculations.

Develop RF schematics, undertake component selection and support PCB layout and design activities.

Conduct RF simulations and modelling using tools such as AWR, ADS, CST, HFSS and MATLAB.

Perform RF testing, measurement, troubleshooting and performance verification using VNAs, spectrum analysers, signal generators, power meters, oscilloscopes and noise figure analysers.

Support environmental and qualification testing, including EMI/EMC, thermal vacuum, vibration and shock testing.

Investigate, diagnose and resolve RF performance issues throughout development, integration and production.

Produce high-quality technical documentation, including design reports, test procedures, verification reports and design review materials.

Work closely with product owners and project engineers to support product development, technical delivery and project milestones.

Support customer technical interactions, engineering discussions and formal design reviews.

Take ownership of RF engineering solutions from initial requirements and architecture through to implementation, integration and delivery.
