Responsibilities
Responsibilities
- Partner with RF measurement and post-silicon teams to translate calibration workflows, de-embedding challenges, and characterization requirements into ML-ready formulations.
- Develop ML models for adaptive calibration (SOLT, TRL, multiline TRL), intelligent de-embedding, and fixture characterization — including Transformers for frequency-domain signal analysis and Vision Models for calibration artifact identification.
- Apply Bayesian/GP optimization for adaptive calibration loop closure, impedance tuner control, and parametric yield optimization; RL (PPO, DDPG, SAC) for automated measurement sequencing and closed-loop RF tuning.
- Build generative models for synthetic S-parameter dataset generation and calibration standard augmentation.
- Write production-ready Python (scikit-rf, PyTorch), C++, and CUDA code; integrate with instrument control frameworks (SCPI, IVI, VISA).
- Benchmark models against hardware measurements and physics-based calibration standards.
Qualifications
Required Qualifications
- Pursuing PhD in EE (RF/Microwave), Applied Physics, CS, or related field.
- Hands-on RF measurement experience: S-parameter characterization, calibration, and de-embedding.
- Strong ML background with experience applying GNNs, Transformers, or Neural Operators to measurement or signal processing tasks.
- Background in Bayesian optimization applied to hardware calibration or measurement tuning.
- Familiarity with SCPI/IVI/PyVISA instrument control and RF measurement automation.
Desired Qualifications
- Experience with advanced calibration techniques (multiline TRL, unknown thru, in-fixture, on-wafer probing).
- Background in load-pull, noise figure, or linearity characterization (IP3, P1dB) for RF device optimization.
- Familiarity with Keysight RF platforms (PNA, PNA-X, ENA) or simulation tools (ADS, RFPro).
- Publications or patents in ML for RF measurement, smart calibration, or adaptive test.
