We are looking for an experienced RF Post-Silicon Validation Engineer to lead the validation and characterization of RF components, including Low-Noise Amplifiers (LNAs), driver amplifiers, RF switches, Power Amplifiers (PAs), beamformers, and transceivers. The ideal candidate will have strong expertise in RF measurement techniques, silicon bring-up, automated validation, and root-cause analysis. This role involves collaborating with cross-functional engineering teams to ensure RF performance, reliability, and compliance with design specifications.

Responsible for leading RF post-silicon validation of LNAs, Driver amplifiers, RF switches, PAs, beamformers, and transceivers. Own characterization of key RF parameters including: 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 brings up and perform deep root cause analysis of performance deviations. Correlate silicon data with simulation results and identify layout, biasing, stability, or measurement related issues. Define and improve RF lab setups including calibration and de-embedding methodologies (SOLT, TRL, ECal). Architect and develop automation frameworks using Python (PyVISA, SCPI) for scalable validation. Support production, Test handover and characterization correlation.

Generate comprehensive validation reports and data summaries. Drive improvements for low-noise and guarded measurements. Mentor junior engineers and coordinate validation planning. Evaluate system performance, run stress simulations, and perform root-cause analysis on structural or programmatic issues. Collaborate with multi-disciplinary engineering teams to establish design specifications and quality assurance benchmarks. Draft detailed technical documentation, engineering schematics, and structural maps to ensure system scalability and safety compliance.

Bachelor of Science degree in Electrical and Computer Engineering, Mathematical Physics, or related field and experience.
