About the role

Key responsibilities & impact
  • Characterize the current readout chain and define the specification
  • Map the existing chain, including assembly time, defect rate, insertion losses, and footprint
  • Define specifications with the operations and RF teams, including number of lines, MXC envelope, insertion loss budget, and thermalization requirements
  • Study and select the mechanical architecture
  • Compare a pre-cabled block with non-threaded connections and a block with a single plug interface to the MXC
  • Benchmark compact components available on the market
  • Build a decision matrix and defend the chosen architecture in design review
  • Design the readout module
  • Produce the CAD model, drawings, and costed bill of materials
  • Select materials and design thermalization to the MXC plate
  • Define torque specifications and perform the SMP tolerance stack-up
  • Choose connectors compatible with future board-edge/PCB integration
  • Write an assembly and inspection procedure for a subcontractor
  • Build and validate a prototype in the cryostat
  • Assemble the prototype and measure real assembly time
  • Perform SOLT/SOLR calibration and S-parameter characterization at room temperature and cold
  • Compare performance against the SMA reference chain and write a measurement report
  • Recommend the path to industrialization
  • Deliver a go/no-go recommendation based on measurement results
  • Build an industrialization roadmap, including inputs for the phase-2 PCB study
  • Work closely with the operations and RF teams to design, prototype, and validate a compact readout module
  • Report to the Cryohardware Development Team

Requirements

What you’ll need

  • Mechanical design for assembly (DFA) and tolerance analysis (stack-ups)
  • Proficiency in CAD (SolidWorks) and technical drawing
  • Material selection and thermal design, ideally with an interest in cryogenic constraints
  • Basic knowledge of RF connectors and coaxial lines is a plus
  • Interest in RF measurements (VNA, S-parameters) and cryogenics
  • Comfortable assembling and testing hardware
  • Rigor and clear technical documentation
  • Ability to structure and present technical choices in a design review
  • Proficient in English
  • No minimum experience required
