Job Description

Senior Applied ML Engineer – Speech, Audio

Nile Bits, LLC.

• Design, fine-tune, and optimize advanced machine learning models for Arabic voice applications. • Work across the full development lifecycle, from data pipeline construction and model experimentation to inference optimization and production deployment. • Benchmark and evaluate TTS and ASR models using Arabic-specific test sets, measuring metrics such as Word Error Rate (WER), naturalness, and dialect coverage. • Fine-tune generative models for voice cloning, zero-shot speaker adaptation, and speech synthesis. • Build and maintain Arabic-focused data pipelines, including: Audio collection and preprocessing Diacritization (Tashkil) Data cleaning and augmentation. • Optimize model inference for production environments using: Quantization KV-cache tuning Streaming inference techniques. • Integrate and evaluate complete speech-to-speech conversational pipelines. • Conduct experiments based on recent research papers and convert findings into production-ready solutions. • Collaborate with engineering and product teams to deploy robust and scalable speech systems.

Job Requirements

  • 5+ years of experience in Machine Learning, Applied AI, or AI Research.
  • Strong programming skills in Python.
  • Extensive hands-on experience with PyTorch and the Hugging Face ecosystem.
  • Proven experience training and fine-tuning neural models for: Text-to-Speech (TTS) Automatic Speech Recognition (ASR) Audio codecs
  • Deep understanding of modern speech architectures such as: Whisper Conformer HiFi-GAN Diffusion-based models
  • Experience with audio processing techniques including: Voice Activity Detection (VAD) Speaker Diarization Neural Vocoders
  • Demonstrated ability to implement and adapt research papers into practical production experiments.
  • Strong understanding of Arabic language challenges, including: Diacritization (Tashkil) Dialectal variations Code-switching
  • Experience with inference optimization techniques such as: Quantization Streaming inference NVIDIA TensorRT
