Job Description
• Design and develop novel streaming ASR architectures, pushing the boundaries of accuracy-latency tradeoffs in production systems.
• Research and prototype LLM-assisted speech-to-text—exploring how large language models can enhance streaming speech recognition and understanding.
• Develop new algorithms for streaming speaker diarization, contextual biasing, and multilingual speech recognition.
• Drive research from initial experimentation through rigorous evaluation to production deployment, working closely with engineering teams.
• Conduct systematic experiments on internal and public benchmarks, with careful attention to evaluation methodology and statistical rigor.
• Contribute to technical publications and represent AssemblyAI's research at top venues.
• Collaborate on research direction and technical strategy, helping shape the roadmap for Speech AI capabilities.
Job Requirements
- Strong research background in speech recognition, with deep understanding of classic streaming architectures (RNN-T, CTC) and modern attention mechanisms.
- Expertise in LLMs and language modeling, with ability to bridge speech and language model research.
- Proficiency in PyTorch and JAX/Flax—you can move fluidly between frameworks and implement complex architectures from scratch.
- Experience with large-scale distributed training and the practical challenges of scaling speech models.
- Track record of publications at top venues (ICASSP, Interspeech, NeurIPS, ICML) or equivalent industry impact.
- Strong experimental methodology—systematic approach to ablations, careful baseline comparisons, and rigorous evaluation.
- Ability to translate research insights into production-ready solutions; comfort working at the interface of research and engineering.
- Excellent communication skills—can articulate complex technical ideas clearly and collaborate effectively across teams.
Benefits
- Health insurance
- 401(k) matching
- Flexible work hours
- Paid time off
