About ai-coustics
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.
About the role
We're looking for a hands-on Growth & Content Marketer to join our marketing team. Reporting to the Head of Marketing and collaborating closely with our Video Specialist, you'll own the execution of content, campaigns, and growth initiatives, ensuring everything we put out is cohesive, on-brand, and built to perform. You'll work with agency partners to implement SEO/SEM strategy, drive B2B lead generation, and support community and event activations, all while producing content that resonates with developers and technical buyers. You're comfortable working autonomously, care about quality, and want to make a real impact at a fast-moving Voice AI startup.
