Stellenausschreibung: Digital Audio Signal Processing Engineer

Arbeitgeber bzw. Arbeitsvermittler: ai-coustics in Hamburg

Branche: IT/IT-Dienstleistung

Kategorie: Informationstechnologie (IT)

Stellenbeschreibung: About us 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 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 We’re looking for a Digital Audio Signal Processing Engineer to own and drive the continued development of our core audio simulation and augmentation systems that underpin our machine learning stack. This system generates training and evaluation data that closely approximates real production audio by starting from clean audio and applying simulation, DSP, and ML-based transformations. It enables realistic training and fine-grained testing of audio AI systems under adverse conditions. You’ll work in a small, focused team of audio, machine learning, and data engineers, collaborating closely to build and evolve the core systems behind our audio AI products. The role is on-site in Berlin . Tasks Own the design and long-term evolution of a core audio simulation and data generation system , with the goal of narrowing the gap between simulated and real-world production audio. Model realistic audio signal chains , spanning acoustic environments, capture conditions, and downstream processing as they occur in real products and voice-agent systems. Translate real customer and production audio into simulation assumptions , identifying what matters perceptually and statistically — and what does not. Develop efficient DSP implementations that work in real-time and streaming use cases as well as in large-scale offline data augmentation. Build and maintain tooling and abstractions that make complex audio simulations configurable and reproducible. Requirements You are an audio & DSP expert : Deep expertise in digital audio signal processing and acoustics, with a strong mathematical foundation and proven experience designing and implementing realistic audio simulations and transformations. You can reason about real-world signal chains, system behavior, approximations, and trade-offs. You are a strong systems engineer : Experience turning research or prototype implementations into robust, high-performance production code, with strong proficiency in Python for rapid development and tooling, and the ability to write highly efficient low-level code in at least one of Rust, C, or C++. You have a startup mindset : You’re comfortable with ambiguity, take ownership, and make pragmatic engineering decisions, with prior experience in a start-up or highly dynamic, product-driven environment. Nice to have : A solid understanding of modern machine learning development workflows and how data and evaluation choices influence ML system behavior. Benefits Opportunity to work at a rapidly growing Voice AI startup , backed by top investors. Compensation and equity: Competitive salary package, additional benefits and stock options, enabling you to take part in the company’s success. Startup Culture: Dynamic, fast-paced environment with passionate and collaborative colleagues. High Impact: Groundbreaking startup at a pivotal growth stage, making a real difference in how people experience audio. Ownership & Autonomy: Take full ownership of projects and ship fast. Work With the Best: World-class team of engineers and builders with ample room for professional growth. Contribute to the Future: Define the landscape of Voice AI technology. If you are ready to lead the charge in revolutionizing Voice AI and drive our startup to new heights, we would love to hear from you. Apply today to join the ai-coustics team!
