Senior Test Engineer — High-Speed Mixed-Signal/RF (V93000, 200Gbps+) at Semtech in Bristol

Job description

Location: Bristol, UK — Semtech Bristol Design Centre Hybrid Working – Monday – Thursday (Friday Flexible) Our Team: When a 200Gbps+ SerDes or a cutting-edge RF SiGe device needs to prove it's production-ready, our Global Test Engineering team is the reason it gets there. We're the technical backbone behind every product in Semtech's semiconductor portfolio — a world-class, multi-site organisation trusted as the centre of excellence for test innovation across every business unit. We don't just run tests; we architect the methodologies, the IP, and the standards the rest of the engineering organisation builds on. If you want your fingerprints on how next-generation high-speed communications products get proven — not just execute somebody else's test plan — keep reading. Job Summary: This is a rare one: the chance to become the technical authority for test development across Semtech's entire mixed-signal and RF portfolio. We need someone who can look at a 200Gbps+ SerDes or CDR architecture and know exactly how to prove it works — at wafer level, at package level, and at volume. You'll architect comprehensive test strategies from first silicon through to mass production, set the DFT and testability standards the wider organisation adopts, and lead the methodologies behind some of the most demanding high-speed communication products in the industry. If your background spans Advantest V93000 architecture, SiGe BiCMOS test challenges, and the kind of signal integrity, jitter and BER analysis most engineers only read about in papers — this is the seat where that expertise finally gets to lead, not just support. Responsibilities: Here's where your expertise takes the lead: Technical Leadership & Architecture Architect and define test strategies for complex mixed-signal / RF SiGe products from concept through production maturity Lead development of innovative test methodologies for high-speed SerDes, CDRs, and signal conditioning products Drive DFT/testability requirements into IC architecture, establishing company-wide standards and best practices Develop and implement advanced test techniques for products operating at >200Gbps data rates Create reusable test IP, libraries, and frameworks that accelerate NPI cycles across product families Perform technical risk assessment and mitigation strategies for test coverage and quality Cross-functional NPI Support Serve as test engineering authority in product architecture reviews and gate meetings Partner with IC design teams from concept phase to ensure optimal test coverage and manufacturability Lead test readiness reviews with stakeholders, providing strategic recommendations Collaborate with Product Engineering to define characterization strategies and correlation methodologies Interface with customer quality teams on test specifications and coverage requirements Architect and launch test solutions that achieve test time targets for complex mixed-signal / RF devices Drive continuous improvement initiatives that reduce NPI cycle time by 10–20% Production Excellence & Scale Ensure seamless transfer of test solutions to high-volume OSATs with >99% first-pass success Drive test cost reduction initiatives delivering year-over-year improvements Establish and monitor KPIs for test effectiveness, efficiency, and quality Mentorship & Knowledge Management Mentor junior engineers, developing the next generation of test engineering contributors Create and maintain comprehensive test methodology documentation and training materials Build strategic relationships with test partners to influence platform development Foster a culture of innovation and continuous learning within the test organisation Minimum Qualifications: What you'll need to hit the ground running: Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field 8+ years of progressive experience in semiconductor test engineering, including 4+ years specifically in mixed-signal/RF test development Proven track recor
