RF Design for Test Engineer (PCB / Microwave)Location: Maldon, EssexSalary: Flexible for the right candidateA technology business designing and manufacturing semiconductor ICs and RF PCB assemblies for global communications markets is seeking an engineer to join the team focusing on design-for-test at RF PCB level. This is not a "production test operator" role - you''ll work closely with engineering to ensure RF boards and assemblies are testable, measurable and manufacturable, and you''ll develop the supporting test approach and hardware alongside that.The roleYou''ll sit at the intersection of RF board-level engineering and test development, supporting products from early design through to production. Key elements include:Working with engineers on RF PCB-level design-for-test, including measurement access, calibration approaches and test strategySupporting or contributing to PCB-level design activities (layout review, stack-up considerations, transmission line structures, connectorisation, test points, etc.)Developing and refining RF test approaches and methodologies to validate boards/subsystemsDesigning/supporting test hardware (e.g., DUT/load boards, fixtures, adapters)Using RF measurements to debug and improve designs (e.g., S-parameters, matching, stability)Supporting production and engineering with structured investigations where test results indicate design or process issuesCreating clear documentation (test methods, procedures, reports) and supporting continuous imp
