Job Title: Speech to Text ML Engineer (Whisper Focus)
Location: 100% Remote
Duration: 6+ Months
Notes:
AI/ML Engineer (Contractor)
Mission: To work on speech-to-text finetuning and inference in multiple languages.
Responsibilities
Train and fine-tune with speech-to-text(ASR) models like Whisper.
Implement training/eval loops (PyTorch + Transformers).
Add data augmentations (noise/reverb/law), VAD, diarization (e.g., Whisper).
Package inference (ONNX / Tensor if needed), expose REST/gRPC, batch/streaming modes.
Optimize RTF (realtime factor), memory
Design training curricula, LR schedules, frozen vs full finetune, LoRA, data mixing.
Build robust test suites: clean/noisy/telephony, accents, domain terminology.
Analyze error types (sub/del/ins), OOV handling, bias; propose targeted fixes.
Experience in ASR, LM fusion, tokenization/normalization, data curation, PyTorch, Hugging Face, CUDA; experience finetuning seq2seq/CTC/RNNT; SoX/FFmpeg; metrics (WER/CER, latency), NeMo, Triton, Torch/TensorRT, LoRA/PEFT.
