Microwave Filter Design Engineer

About Filtronic Filtronic is a leading designer and manufacturer of high-performance radio frequency, microwave and millimetre-wave subsystems for mission-critical communication networks. Since 1977, we have worked with global technology leaders across telecommunications infrastructure, aerospace and defence, space, and critical communications.

We design and manufacture advanced RF, microwave and mmWave solutions across frequencies from 300MHz to 175GHz, supporting customers in some of the world’s most demanding communications environments.

The opportunity We are looking for a Microwave Filter Design Engineer to join our engineering team and support the design, development, test and introduction of high-performance RF and microwave filter products.

This role would suit an engineer with experience in RF, microwave, filter, antenna, electromagnetic, communications or hardware design who wants to develop deeper expertise in microwave filter engineering. You will work alongside experienced engineers on real product development projects, taking designs from early concept through simulation, prototyping, verification and release into manufacture.

We are looking for someone with strong engineering fundamentals, practical curiosity, and the motivation to grow into a specialist microwave filter design role.

What You’ll Be Doing You will:

• Design and develop RF and microwave filters and related sub-systems under the guidance of senior engineers.
• Use simulation and design tools to model, optimise and evaluate filter performance.
• Support prototyping, build, tuning and test activities in the lab.
• Carry out measurements using RF test equipment such as VNAs and other microwave laboratory equipment.
• Help prepare design documentation, test plans, test reports and data packs.
• Support design verification and validation activities.
• Work with manufacturing, test, quality and project teams to resolve technical issues during product development and introduction.
• Contribute to design reviews, peer reviews and technical problem-solving.
• Support continuous improvement of filter designs, design methods and engineering processes.
• Develop knowledge of manufacturability, tolerance analysis, power handling, thermal effects, reliability and compliance requirements

Requirements We are interested in hearing from candidates who meets most of the following:

• A degree, HND/HNC, apprenticeship background or equivalent practical experience in RF, microwave, electronic, electrical or communications engineering.
• Experience or strong academic understanding of RF and microwave engineering principles.
• Exposure to filter design, RF circuit design, electromagnetic simulation, antenna design, microwave components or related technologies.
• Familiarity with RF design or simulation tools such as Microwave Office, CST Studio, HFSS, ADS or similar.
• Practical laboratory experience, ideally including RF measurement, VNA use, tuning, test setup or fault investigation.
• Ability to interpret technical drawings, schematics, simulations, specifications and test data.
• A structured approach to engineering documentation and problem-solving.
• Good communication skills and the ability to work with engineers from different disciplines.
• A willingness to learn, ask questions and develop specialist expertise.

What kind of person will do well here? You are likely to enjoy this role if you:

• Like solving complex technical problems.
• Enjoy combining simulation, analysis and hands-on lab work.
• Are comfortable learning from experienced engineers.
• Care about detail, evidence and robust engineering decisions.
• Want to build a long-term career in RF and microwave design.
• Are motivated by working on high-performance technology used in real-world communication systems.
