Job Description

We are seeking a junior RF Validation Engineer to lead post-silicon validation and characterization of high-performance RF and mixed-signal ICs. This role requires strong RF fundamentals, lab expertise, and the ability to architect automated validation frameworks. The candidate will drive silicon bring-up, ensure datasheet compliance, and collaborate cross-functionally from development through production release.

Responsibilities 

Lead RF post-silicon validation of LNAs, Driver amplifiers, RF switches, PAs, beamformers, and transceivers.
•    Own characterization of key RF parameters including:
o    S-parameters (Gain, Return Loss, Isolation), Smith chart, Noise Figure, IIP3 / OIP3, P1dB, Phase Noise, EVM, ACPR, Harmonics and Spurious emissions
•    Perform CW, pulsed, modulated and timing validation where applicable.
•    Execute validation across voltage, temperature, and process corners.
•    Drive silicon bring-up and perform deep root cause analysis of performance deviations.
•    Develop automation frameworks using Python (PyVISA, SCPI) for scalable validation.
•    Support production, test handover and characterization correlation.
•    Generate comprehensive validation reports and data summaries.

Requirements

A bachelor’s or master’s degree in Electrical engineering. 
-    0-2 years of experience in RF Bench Validation and Characterization.
-    Strong understanding of RF fundamentals: impedance matching, stability Analysis, noise mechanisms, and linearity concepts.
-    Hands-on experience with VNAs, spectrum/signal analysers, RF signal generators, power meters, and noise figure setups.
-    Understanding of lab instruments like power supplies, DMMs, oscilloscopes, network analyzers, spectrum analyzers, PNAx, etc.

Preferred
-    Exposure to automation-driven validation and large-scale characterization matrices.
-    Experience in soldering small SMD components.
-    Knowledge of communication protocols like SPI, I2C, I3C, SCPI, etc.
-    Knowledge of PCB design.
