The Machine Translation and Multilingual Intelligence team is looking for outstanding engineers and scientists to build the next generation of speech-to-speech translation technology, so our users can talk naturally with anyone, in any language, in real time.
You will take part in the next revolution at the confluence of machine translation, speech technology and human-computer interaction. We are building end-to-end speech-to-speech translation: models that listen, translate and speak in a single system, with low latency and natural, expressive output.
You will:
We are looking for people with a deep, real passion for technology who enjoy collaborating with researchers, engineers and designers to put this technology in the hands of millions of customers.
Research or product experience in speech-to-speech or speech-to-text translation, especially end-to-end, streaming or simultaneous approaches.
Experience in text-to-speech and speech generation, such as neural TTS, speech tokenizers and audio codecs, expressive or multilingual synthesis.
Experience with large language models or multimodal (audio + text) foundation models, including pre-training, fine-tuning or reinforcement learning.
Experience designing and deploying real-world, large-scale, user-facing speech recognition, translation or synthesis systems, including on-device or low-latency inference.
Familiarity with speech and translation evaluation, such as WER, BLEU/chrF/COMET-style metrics, MOS and side-by-side human evaluation, and latency metrics.
Ability to formulate a research problem, then design, run experiments and implement solutions in Python and C/C++.
Publications in relevant venues (e.g. Interspeech, ICASSP, ACL, EMNLP, NeurIPS, ICML) are a plus.
Excellent spoken and written communication skills.
M.S. or PhD in Computer Science or a related field.
Experience with machine learning for speech recognition, machine translation, NLP or speech synthesis.
Hands-on experience with deep learning toolkits such as PyTorch, JAX or TensorFlow.

We’re a diverse collective of thinkers and doers, continually reimagining what’s possible to help us all do what we love in new ways. And the same innovation that goes into our products also applies to our practices — strengthening our commitment to leave the world better than we found it. This is where your work can make a difference in people’s lives. Including your own.
