Lead Financial Data Scientist

What you will do: Build and ship core ML models for a speech-driven behavioral engine. Own end-to-end modeling from raw, long-form audio and layered annotations to production inference. Design audio features/embeddings, train and evaluate a suite of models, and deliver reproducible pipelines that meet accuracy, robustness, latency, and cost targets. Your skill set and experience: 5+ years building production ML systems, including 2+ years in speech/audio. Speech & signal processing: VAD, diarization, segmentation, denoising, spectral features (log-mel/MFCC), prosody (pitch/energy), long-form audio handling. SOTA audio models & embeddings: Wav2Vec2, HuBERT, wavLM (or similar); fine-tuning/self-supervised learning; contrastive/metric learning for downstream tasks. Data excellence: SQL, Python data stack (Pandas/Polars), ETL for audio+metadata, stratified sampling, leakage prevention, feature stores. ML Training: PyTorch, Hugging Face Transformers/Hub, mixed precision, hyperparameter tuning, transfer learning, cross-validation. Evaluation discipline: golden sets, robust speaker/content splits, ROC/PR/calibration, fairness/bias checks, ablations, drift/shift detection on embeddings and audio quality. MLOps, serving & reproducibility: FastAPI/gRPC around HF/torchaudio models, experiment tracking (W&B/MLflow), artifact/model versioning, CI/CD, observability, scalable batch/streaming inference. Proven ability to create and document novel IP (methods, architectures, or training/eval techniques) with clear prior-art awareness. Nice to have: Tooling: SpeechBrain, Lightning, OpenSMILE/Praat, Kaldi/Conformer/Emformer, Label Studio. Multimodal: ASR (e.g., Whisper) + paralinguistic features; emotion/prosody modeling; speaker embeddings (x-vectors, ECAPA-TDNN). Performance & deployment: quantization/distillation, Triton/CUDA basics, distributed training, real-time/streaming inference, on-device DSP (Rust/C++). Publications/patents/competition results demonstrating novel audio modeling work.
