Senior Validation Engineer — High-Speed PCB & RF Lab

Sierra Wireless; West of England; On-site; GBP 65,000 - 90,000; Full time

Job summary

Semtech in Stansted is seeking a Senior Validation Engineer to design high-speed validation PCBs and characterise devices at 25Gbit/s and beyond, from schematic capture to bring-up and measurement.

You’ll define stack-up, apply impedance and SI practices, debug on the bench, and build test automation in Python to speed measurements. You’ll work with designers, product, test and applications engineers in a collaborative validation team.

Qualifications

• BSc/MSc in Electrical/Electronic Engineering (EEE/ECE), or HNC/HND with equivalent practical experience
• Strong hands-on Cadence Allegro experience, covering both schematic and layout
• Proven high-speed PCB design experience: stack-ups, materials, controlled impedance and signal integrity
• Experience designing and debugging RF and data comms PCBs
• Able to stay focused and positive under pressure in a fast-paced R&D environment
• A natural team player with good communication skills
• Self-motivated and comfortable learning new tools and techniques independently
• Strong attention to detail and an analytical, creative approach to problem-solving

Responsibilities

• Design validation PCBs for new product evaluation using Cadence Allegro, from schematic capture and stack-up definition through to layout and release
• Apply high-speed and RF design practice, including material selection, controlled impedance and signal integrity, to boards operating at 25Gbit/s and above
• Bring up, debug and characterise RF and data comms boards in the lab
• Carry out benchtop characterisation of new silicon and write clear, accurate validation reports
• Help identify and select the right lab equipment for validating new products
• Build test automation software in Python (or similar) to make measurements faster and more repeatable
• Work closely with designers, product, test and applications engineers, and take part in validation review meetings
• Support new product design meetings and help shape how devices are tested
