Career

LLMs Engineer

  • Ha Noi, Ho Chi Minh
  • Fulltime

Key Responsibilities

  • Research, design, and develop state-of-the-art Text-to-Speech (TTS) systems for natural, real-time human-computer interaction.

  • Train, fine-tune, and optimize neural TTS models (e.g., Tacotron, FastSpeech, VITS, WaveNet) to achieve high-quality, expressive, and low-latency speech synthesis.

  • Build multilingual and multi-speaker TTS pipelines, with controllable style, prosody, and emotional tone.

  • Collaborate with ASR and NLP/LLM teams to ensure smooth end-to-end voice interaction systems.

  • Explore and integrate multimodal approaches where TTS works with text, speech, and vision for richer interaction.

  • Develop evaluation frameworks and metrics for TTS quality (MOS, intelligibility, latency).

  • Research and implement model compression, quantization, and deployment techniques for real-time inference on edge devices.

  • Stay updated on the latest research in speech synthesis, voice cloning, and generative models (e.g., diffusion-based speech synthesis).

Requirements

  • Bachelor’s, Master’s, or PhD in Computer Science, AI, Speech Processing, Computational Linguistics, or related field.

  • Strong programming skills in Python, with experience in PyTorch/TensorFlow.

  • Solid knowledge of deep learning, signal processing, and speech synthesis.

  • Hands-on experience with TTS frameworks (e.g., ESPnet, NVIDIA NeMo, Fairseq, Coqui TTS).

  • Understanding of vocoder models (WaveNet, HiFi-GAN, WaveGlow, etc.).

  • Familiarity with ASR, NLP, or LLMs to build integrated voice-AI solutions.

  • Knowledge of deployment optimization: low-latency inference, edge AI, GPU/TPU acceleration.

Preferred Qualifications

  • Experience in deploying real-time TTS systems in production.

  • Background in multilingual/multispeaker TTS and voice cloning.

  • Research or practical experience with expressive/emotional TTS.

  • Knowledge of reinforcement learning from human feedback (RLHF) for speech quality improvement.

  • Expertise in distributed training and large-scale model serving.
