Zusammenfassung

botario is looking for engineers to build the voice technologies behind AI Voice Agents, delivering natural, real-time conversations with robust performance. You will work on end-to-end TTS/STT systems, optimizing latency and quality across streaming pipelines.

The role emphasizes hands-on ML work, with Python and PyTorch, in an agile team, to produce production-ready speech AI solutions for real-world conditions.

Qualifikationen

• Hands-on experience with speech technologies such as TTS/STT or real-time audio processing.
• Strong Python programming skills and ML background with motivation to specialize in speech AI.
• Understanding why low latency is critical for natural conversations and experience optimizing real-time systems.
• Experience deploying speech AI models in production environments is a plus.
• Collaborative mindset and experience working in agile teams.

Aufgaben

• Develop and improve proprietary TTS and STT systems from model development to real-time streaming inference.
• Optimize latency across the voice pipeline, including time-to-first-audio and streaming synthesis.
• Improve voice quality and naturalness through prosody and pronunciation work.
• Evaluate open-source speech models and integrate promising approaches into the tech stack.
• Measure latency, quality benchmarks and conduct listening tests.
• Collaborate with engineers and cross-functional teams in an agile environment.

Jobbeschreibung

Your new roleBuild 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.
