RF PCB Layout Engineer – Complete Existing LoRa / LTE / GNSS Board

We are looking for an experienced RF PCB Layout Engineer to review and complete an existing multi-radio PCB design. This is not a design-from-scratch project. The schematic, component placement and most signal/power routing are already completed. The remaining work is focused mainly on RF layout finalization and production-readiness review. Required experience: Sub-GHz / LoRa RF PCB routing LTE RF layout GNSS RF layout 50-ohm controlled-impedance routing RF matching networks antenna feed layout ground return and stitching-via strategy RF keep-outs and isolation multilayer PCB stack-up EMI/EMC-aware layout KiCad The selected engineer will be required to review the existing PCB, complete/correct the RF sections and bring the board to fabrication-ready status. Expected deliverables include: completed RF routing impedance/layout review RF matching and grounding review final DRC review manufacturability review final production-ready PCB files Gerbers, drill files and fabrication outputs Important: This is an existing proprietary design. Detailed schematics, PCB files, architecture, component information and RF design details will only be provided after NDA execution. Please apply only if you have proven hands-on experience with RF PCB layout, especially LoRa/Sub-GHz, LTE or GNSS boards. Please provide examples of previous RF PCB work.
