RF System design Engineer

About the Role
We are hiring a RF & Hardware Systems Engineer to lead the end-to-end hardware architecture and RF system design for 4G/5G small and macro cell base stations.
This is a high-impact role working across RF design, mixed-signal PCB, power systems, and SoC integration, building production-grade telecom infrastructure.

Key Responsibilities
Own RF & hardware architecture for 4G/5G small cell products
Design full RF signal chain (antenna → LNA/PA → transceiver → baseband)
Perform link budget, noise, EVM, ACPR, and sensitivity analysis
Lead multi-layer PCB design (RF + high-speed digital integration)
Define clocking, synchronization (PTP/SyncE), and power architecture
Drive hardware bring-up, RF validation, and compliance testing
Ensure adherence to 3GPP, TEC, WPC, BIS standards
Collaborate with SoC, firmware, and manufacturing teams

Required Skills
Strong expertise in RF systems & circuit design (LNA, PA, filters, matching)
Experience in mixed-signal PCB design & RF layout
Knowledge of RF transceivers (ADRV/AD9xxx or similar)
Understanding of clocking & synchronization (PTP, GPS, PLL)
Familiarity with high-speed interfaces (PCIe, JESD204B, USB3)
Hands-on with RF test equipment (VNA, spectrum analyzer, signal generator)
Working knowledge of 3GPP standards (TS 38.104 / 36.104)

Good to Have
Experience with LTE / 5G small cell hardware design
Exposure to CPRI/eCPRI or O-RAN architectures
Knowledge of DPD and PA linearisation
Experience with India regulatory certifications (TEC, WPC, BIS)
