Fabrication Engineer for RF components

What you’ll do

Your responsibilities

• Focus on the mechanical realisation and development of the critical Triode components, including the Anode, Cathode, and Grid.
• Oversee the development of laser micro-machining and other advanced manufacturing technologies for the grid manufacturing, utilising specialised materials.
• Define and follow up on feasibility studies for High-Precision Machining: achieving sub-10 micron tolerances, required surface roughness, and precise parts fit-up.
• Define and follow up on feasibility studies for vacuum brasing cycles and/or electron beam welding (EBW) procedures for dissimilar materials, focusing on the metallurgical integrity of joints between oxygen-free copper, technical ceramics, and other high-performance alloys.
