Senior Core Services Engineer

We are seeking a talented software engineer with strong experience in backend web services, infrastructure and data pipelines to advance our core mission: using the world’s most advanced technology for emotion understanding to build empathy and goal-alignment into AI. Join us in the heart of New York City, or wherever you are located, and contribute to our endeavor to ensure that AI is guided by human values, the most pivotal challenge (and opportunity) of the 21st century.

About Us

Hume AI is a Series B research lab dedicated to building artificial intelligence that is directly optimized for human well-being. EVI 3, our next flagship foundational speech-language model that powers empathic AI assistants for any application is available to test at demo.hume.ai. We also recently released Octave 2 (Omni Capable Text and Voice Engine), the second generation of our frontier voice AI model for text-to-speech.

Our speech-language models understand subtle tones of voice, word emphasis, facial expressions, and listener reactions. EVI 3 unifies transcription, language, and speech in real time, enabling expressive, emotionally intelligent conversations using any voice or personality created with a prompt. Rated higher than GPT-4o on empathy, expressiveness, naturalness, and speed, it can instantly speak in over 100,000 unique voices and styles, stream language, emotion, and reasoning simultaneously, and respond in under 300 ms for truly conversational interactions. Try it at demo.hume.ai

Octave 2 TTS is a state-of-the-art speech-language AI model trained to both understand and synthesize language and speech. Unlike traditional TTS systems, it interprets how a script informs the rhythm, tune, and timbre of delivery, whether whispering a secret, shouting triumphantly, or calmly explaining a fact, and reproduces not just vocal timbre but also the personality of any speaker.

Our mission is to enable a future in which technology draws on emotional understanding to better serve human goals. We conduct groundbreaking scientific research published in leading journals like Nature and support The Hume Initiative, a non-profit that released the first concrete ethical guidelines for empathic AI (www.thehumeinitiative.org). You can learn more at hume.ai and read about us in WIRED, Forbes, and VentureBeat.
