Senior Validation Engineer – High-Speed PCB Design & Signal Integrity (25G+)

Location: Stansted, UKWork pattern: On-site (Monday – Friday)Our TeamWant to work at the sharp end of how the world’s data moves? Join an ambitious and collaborative engineering team in Stansted, part of Semtech’s Signal Integrity Products group, developing the silicon that powers hyperscale data centres, enterprise networks and wireless infrastructure.We work hand in hand with a world-renowned design group, and our culture is open, inclusive and driven by innovation.

Read on to fully understand what this job requires in terms of skills and experience If you are a good match, make an application.

Here, validation isn’t a back-room function.

You’ll design the boards, own the bench and shape the product.Job SummaryReady to put your PCB design skills to work on the most advanced silicon in the industry?As a Senior Validation Engineer, you’ll design the high-speed validation PCBs used to evaluate next-generation devices, then characterise those devices in the lab at data rates of 25Gbit/s and beyond.

You’ll take a design from schematic, through stack-up and layout, to bring-up and measurement, and your results will directly influence what ships.No two weeks look the same.

One week you might be defining the stack-up and controlled-impedance strategy for a new evaluation board; the next you’ll be debugging signal integrity on the bench, automating tests in Python, or presenting your findings in a validation review.You’ll work with experienced engineers, industry-leading test equipment and a team that values your judgement.

Bring the expertise; we’ll bring the silicon, the kit and the influence.ResponsibilitiesDesign validation PCBs for new product evaluation using Cadence Allegro, from schematic capture and stack-up definition through to layout and releaseApply high-speed and RF design practice, including material selection, controlled impedance and signal integrity, to boards operating at 25Gbit/s and aboveBring up, debug and characterise RF and data comms boards in the labCarry out benchtop characterisation of new silicon and write clear, accurate validation reportsHelp identify and select the right lab equipment for validating new productsBuild test automation software in Python (or similar) to make measurements faster and more repeatableWork closely with designers, product, test and applications engineers, and take part in validation review meetingsSupport new product design meetings and help shape how devices are testedMinimum QualificationsBSc/MSc in Electrical/Electronic Engineering (EEE/ECE), or HNC/HND with equivalent practical experienceStrong hands-on Cadence Allegro experience, covering both schematic and layoutProven high-speed PCB design experience: stack-ups, materials, controlled impedance and signal integrityExperience designing and debugging RF and data comms PCBsAble to stay focused and positive under pressure in a fast-paced R&D environmentA natural team player with good communication skillsSelf-motivated and comfortable learning new tools and techniques independentlyStrong attention to detail and an analytical, creative approach to problem-solvingPreferred QualificationsPCB signal integrity simulation experiencePython or similar for test automationExperience testing optical components, ICs or modulesLab measurement experience at 25Gbit/s and aboveData analysis skills and the ability to present complex data clearlyCareer Growth PhilosophyAt Semtech, we believe that innovation starts with people.

We’re committed to supporting your professional development through collaboration, structured learning and a culture that rewards initiative.Our pay-for-performance culture celebrates meaningful contributions, and as a senior engineer you’ll have the scope to influence product validation, test strategy and board design practice.Join us, and be part of a team that’s building the future of connectivity, together.The intent of this job description is to describe the major duties and responsibilities performed by incumbents of this job.
