Voice AI Engineer (all genders)

descriptionDescrizione dell’offerta

Your new role Build voices that power real conversations. At botario, you'll develop the text-to-speech and speech-to-text systems behind our AI Voice Agents—from the underlying models to low-latency, production-ready deployment. You'll help create voice experiences that sound natural, respond in real time, and perform reliably even in challenging real-world conditions. The work you‘ll do • Develop and continuously improve our proprietary text-to-speech (TTS) and speech-to-text (STT) systems, from model development to real-time streaming inference. • Optimize latency across the entire voice pipeline, including time-to-first-audio, streaming synthesis, and efficient model serving—because every millisecond matters. • Improve voice quality and naturalness by working on prosody, pronunciation, and robustness under real-world audio conditions. • Evaluate the latest open-source speech models and integrate the most promising approaches into our technology stack. • Measure and validate your work through latency profiling, quality benchmarks, and listening tests. • Collaborate closely with engineers and cross-functional teams in an agile environment. The qualifications you need • Hands-on experience with speech technologies such as text-to-speech (TTS), speech-to-text (STT), real-time audio processing, or speech model inference. • Familiarity with concepts such as audio codecs and speech tokenizers—or a strong machine learning and PyTorch background with the motivation to specialize in speech AI. • Strong Python programming skills and the curiosity to explore unfamiliar technical challenges. • A solid understanding of why low latency is critical for natural conversations and experience optimizing real-time systems. • Ideally, experience deploying speech AI models in commercial production environments. • A collaborative mindset and experience working in agile teams. What we can offer you • The opportunity to shape the future of AI-powered communication in an innovative company with a clear vision. • Flat hierarchies, short decision-making paths, and the freedom to contribute ideas and work with the latest technologies. • A modern office at Bremen's Europahafen with waterfront views. • Company fitness, BusinessBike, and access to our company boat. • Funding for the e-learning courses of your choice to support your professional development. • Regular knowledge sharing through internal meetups and participation in AI and technology events. • Exciting international customers across a wide range of industries. • A competitive salary and employee participation program. • 30 days of annual leave and flexible part-time options. • High-end hardware, height-adjustable desks, and multi-monitor workstations. • A family-friendly culture that supports work-life integration and has been officially recognized as a family-friendly employer.
