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.

Renesas Electronics · Edinburgh

Design and verify CMOS analog blocks such as amplifiers, oscillators, LDOs, comparators and reference/biasing circuits for custom ASICs, balancing performance, area, power and timescale. The role carries technical leadership of sub-systems from specification through to production ramp, guiding layout, DFT and test engineers, driving silicon debug and lab evaluation, and mentoring less experienced team members.
