Platform Engineer (AWS)

Voice is becoming the primary interface for technology. For the first time in history we can use natural language to control and interact with our devices services and applications and were only at the beginning of the adoption of Voice and Physical AI across industries. Current voice interactions however still lack a fundamental human skill: nuanced understanding of audio scenes and environments. Navigating complex auditory scenes distinguishing between multiple voices or focusing on a main speaker are all part of the challenge of teaching machines to hear like human beings.

At ai-coustics were building the audio intelligence layer and developer tooling to enable more robust and intelligent voice agents and Physical AI applications. Today Voice AI companies like Perplexity PolyAI LiveKit AssemblyAI or Telli use our SDK to prepare their agents for real-world acoustic challenges. Our models power thousands of agents worldwide and process millions of hours each month.

We are backed by leading early-stage investors including Connect Ventures Partech Inovia Capital as well as angel investors from HuggingFace DeepMind and Amazon with deep expertise in AI and developer infrastructure. These partners share our vision and are helping us build a world-class team operating with high levels of responsibility and velocity. We look for people who take ownership think systemically and want to solve challenging real-world problems in close collaboration with our customers.
