About the role
We are seeking an AI Engineer: Speech/Audio to join our growing team and drive innovation in next-generation audio AI technologies. This role focuses on Large Audio Language Models (LALMs), Large Audio Reasoning Models, and Speech-to-Speech (S2S) systems that can understand, reason over, and generate audio with human-like capabilities.
Key Responsibilities
- Design, develop, and deploy Large Audio Language Models (LALMs) capable of native audio understanding, reasoning, and generation.
- Build Large Audio Reasoning Models that perform complex chain-of-thought reasoning over speech and audio inputs, including medical, technical, and conversational domains.
- Contribute to Speech-to-Speech (S2S) system development, including speech understanding, dialogue management, and speech synthesis components.
- Research and implement alignment mechanisms between speech encoders and LLM backbones using lightweight adapters, LoRA, and efficient fine-tuning strategies.
- Design efficient speech tokenization and temporal compression techniques suitable for long-form audio reasoning and multi-turn spoken dialogue.
- Build comprehensive evaluation frameworks for audio reasoning capabilities, including benchmarks for speech QA, audio understanding, and reasoning accuracy.
- Optimize inference pipelines for low-latency, streaming applications in speech systems.
- Collaborate with cross-functional teams to transfer research innovations into production systems and customer-facing applications.
- Contribute to technical documentation, research write-ups, and publications at top-tier venues (NeurIPS, ICML, ACL, Interspeech).
Minimum Qualifications
- Ph.D. required in Computer Science, Electrical Engineering, or a related field with a focus on speech, audio ML, or multimodal learning.
- 2+ years of industry or applied research experience in speech/audio AI, Large Language Models, or multimodal systems.
- Demonstrated applied research contributions through publications, patents, or shipped products in speech/audio AI or LLMs.
- Strong proficiency in Python and PyTorch, with hands-on experience in GPU-accelerated training for large-scale models.
- Solid understanding of speech and audio signal processing, acoustic modeling, and audio representations.
- Working knowledge of modern LLM architectures (Transformers, SSMs) and training paradigms including instruction tuning and alignment methods.
- Familiarity with modality alignment techniques: adapter-based integration, cross-modal attention, or audio-text fusion methods.
- Strong experimentation habits: clean code, systematic ablations, reproducibility, and clear technical communication.
Preferred Qualifications
- Publication record at top-tier venues (NeurIPS, ICML, ICLR, ACL, Interspeech, ICASSP) in audio language models, speech reasoning, or multimodal learning.
- Hands-on experience building or fine-tuning Large Audio Language Models (e.g., Qwen-Audio, SALMONN, LTU, Gemini Audio).
- Experience with speech representation pretraining (HuBERT, Wav2Vec 2.0, Whisper, WavLM) and discrete speech tokenization.
- Familiarity with Speech-to-Speech components: neural audio codecs (EnCodec, SoundStream), vocoders, or speech synthesis systems.
- Experience with audio reasoning benchmarks (AIR-Bench, MMAU, AudioBench) or building evaluation harnesses for audio QA.
- Hands-on experience with distributed training (FSDP, DeepSpeed) and inference optimization (ONNX, TensorRT, quantization).
- Familiarity with speech frameworks such as ESPnet, SpeechBrain, NVIDIA NeMo, or Fairseq.
- Experience with multilingual speech systems, code-switching, or domain adaptation for specialized applications (medical, legal, technical).
- Background in evaluating safety, bias, hallucination, or adversarial robustness in audio language models.
