ai-coustics is building the reliability layer for Voice AI, the system that closes the gap between raw audio input and reliable machine understanding in production.
By combining state-of-the-art speech and audio research with real-time, production-grade SDKs, we test, observe, and enable Voice AI systems to work in any environment.
Our software is used by fast-growing Voice AI companies across Europe and the United States whose products require reliable performance at scale: call center agents, voice agents, telephony apps, and enterprise voice assistants.
We believe voice will become the main interface for technology and ai-coustics is building the foundational infrastructure to make audio input reliable, measurable, and easy to deploy.
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.
If you're motivated by developing technology that is used in practice, shaping an emerging category and setting a new standard for how voice AI works in the real world, you'll feel at home at ai-coustics.
Role Overview ai-coustics is seeking a Systems Software Engineer to join our Systems team, working at the core of our real-time Audio AI SDK and inference infrastructure.
In this role, you will help maintain, optimize, and expand the SDK that powers ai-coustics' speech enhancement and Voice AI products across a wide range of platforms, runtimes, and languages.
You will work primarily on our Rust-based inference and systems codebase, which underpins the Airten real-time inference engine, DSP modules, telemetry, model execution pipe.
