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.
