Work experience

Sr. Lead Engineer at NI (National Instruments) - Emerson, Nov 2024 - Present · 1 yr 11 mos, Bengaluru, Karnataka, India

Lead System Validation Engineer at NXP Semiconductors, Dec 2020 - Nov 2024 · 4 yrs, Bengaluru, Karnataka, India, Simulated UWB chipset (Helios-1) receiver chain in MATLAB; Optimized AGC algorithm with gain statistics (settled gain, settling time, gain error, table selection). Corrected sensitivity measurements (Improved UWB sensitivity by 2–3 dB through PHY layer tuning; corrected error floor and monotonicity issues in MATLAB test framework), developed and executed Tx/Rx validation including NBIC (Narrow Band Blocker) feature tests. Supported UWB silicon bring-up and PHY layer characterization to improve sensitivity (BER) performance. Owned end-to-end validation lifecycle for FM/AM Analog Radio receivers (3 chipsets) (automotive infotainment): built conducted RF setups, powered on silicon, performed sanity checks, executed measurement cycles, and debugged issues to closure. Executed comprehensive RF receiver measurements: Sensitivity, Noise Figure, Selectivity, Desensitization, Linearity, IP3, AGC, IM3, Blocker, THD+N, SNR, AGC Steps and Attack/Decay Time Constants. Enabled and tuned Channel Equalizer and Phase Diversity at firmware level; implemented and characterized AGC algorithms for FM receiver chain optimization. Led PVT (Process, Voltage, Temperature) characterization across all chipset corner samples; supported legacy Car Radio customer requirements ensuring backward compatibility. Mentored 3 Engineers on validation frameworks and debugging; automated report generation using Python and MATLAB, reducing manual effort and turnaround time (Reduced report generation time by ~50% via Python/MATLAB automation).

RF VALIDATION ENGINEER at Broadcom Inc., Jun 2017 - Nov 2020 · 3 yrs 6 mos, bangolore, Performed RF validation of Wi-Fi modules (Validated 3 generations of Wi-Fi modules across 4 WLAN standards) for smartphones: PA, LNA, T/R switch characterization per IEEE WLAN 802.11 b/g/n/ac/ax standards. Built and calibrated validation stations from scratch; executed RF parameter measurements (EVM, Sensitivity, TX/RX Throughput, Tx Power Control, Spectrum Mask, PER/BER, IQ Mismatch) on Wi-Fi/BT combo platforms. Validated advanced features: Scan Core, Tx Beamforming; generated industry-standard validation reports for design and system team using Python Framework.
