Working on‑site from our R&D offices in Rickmansworth, this hands‑on role is focused on supporting the RF Design team with new developments, primarily through testing, tuning, reworking, and modifying RF PCBs and assemblies. The responsibilities include maintaining the stock of components and consumables, assisting with test equipment calibration arrangements, and organising the RF laboratory. The role involves various support tasks within the RF engineering team, including building and testing boards, modules, and chassis.

• Support the RF team with maintaining the lab area.
• Organise storage of development hardware.
• Arrange ordering of equipment, parts and lab supplies as necessary.
• Ensure test and rework benches are suitably equipped and maintained.
• Keep the lab area tidy.
• Ensure all lab equipment is functional and arrange repair as necessary.
• Assist with annual calibration of lab equipment (VNAs etc).
• Modify boards to IPC-610.
• Test and measure RF PCBs and their assemblies using VNA, oscilloscope, spectrum analyser, etc.
• Set up and operate test equipment to evaluate RF products and assemblies under different environmental conditions.
• Construct and assemble prototype boards and chassis.
• Construct wiring looms.

Our ideal candidate will have previous experience in the construction and testing of RF circuits or similar devices. The ability to read schematic and PCB layout diagrams accurately is essential, as is the ability to follow test procedures and document results meticulously. Proficiency in using RF/Electronic test equipment, such as VNAs, spectrum analysers, signal generators, power meters, oscilloscopes, and DVMs/DMMs, is required.

Additionally, the candidate should have experience in writing and editing Python and LabVIEW scripts to control test equipment and run automated testing.

While some experience with mechanical modification is a plus, it is not essential.

Familiarity with Microsoft Office applications (Word, PowerPoint, Excel) or similar software is necessary.
