Drive validation strategy for next-generation high-speed semiconductor devices, architecting end-to-end test solutions spanning software, hardware and documentation. Build Python or LabVIEW automation, take precision lab measurements at 10Gbit/s and above, and apply signal integrity expertise to schematic entry and PCB layout in Altium. Lead validation reviews and mentor engineers within a Bristol R&D team.

Semtech · Bristol

Graduate role validating next-generation high-speed semiconductor devices, working hands-on in the lab from week one. You'll build test automation in Python or LabVIEW, take measurements on components running at 10Gbit/s and above, and learn high-speed signal integrity with Altium PCB tools. Based in Bristol, hybrid with four days in office.

Pragmatic Semiconductor · Durham

Support 300mm wafer fabs by introducing new process technology, ramping yield and providing RMA support. Monitor electrical performance, SPC and OOC parameters, run DOEs and drive defect characterisation and root-cause analysis. Work closely with process integration, principal engineers and cross-functional teams on high-volume manufacturing.

Pragmatic Semiconductor · Durham

Lead the development, qualification and transfer of back-end semiconductor assembly processes into high-volume manufacturing, with particular focus on laser processing, die singulation, wafer-on-frame debonding and advanced packaging. Design and execute DOEs, set process windows and control plans, and mentor engineers while supporting new product introductions and customer-driven transfers.

Platform Recruitment · United Kingdom · £55,000 – £75,000 pa

Design and develop advanced sensing electronics from concept through multi-layer PCB layout and manufacture, using Altium, Xilinx FPGAs and DSP techniques. Lead testing, failure analysis and root-cause repair of high-precision systems while working with technical directors on analogue and data-acquisition challenges. A visible technical-authority role within a small expert team.

Redline Group · Glasgow · £60,000 – £80,000 pa

Lead the test department, providing and maintaining in-circuit and functional test equipment for in-house production. Requires developing PCBA test solutions, ideally on Keysight platforms, plus managing a test engineering team through mentoring, performance management and hiring. Based in East Sussex within a semiconductor market leader.

Octagon Group · Manchester · £30,000 – £40,000 pa

Supports yield and quality improvements across wafer fabrication and assembly, reviewing lots on hold and leading root cause analysis and corrective actions. Maintains automotive process controls, PROMIS routes and yield reports, and works with Python/R and SPC tools on new product introduction and Six Sigma projects in a cleanroom manufacturing setting.
