Job Description
About UsInvorto is our Voice AI product, bringing intelligent voice agents to real-world customer and operational use cases. Our voice pipeline is built in Python, running an STT → LLM → TTS architect
Key Highlights
- Design and build automated testing and quality frameworks for our STT → LLM → TTS voice pipeline, built on Pipecat
- Evaluate and benchmark STT, LLM, and TTS/ASR components on accuracy, latency, naturalness, and robustness across accents, languages, and real-world audio conditions
- Work hands-on with STT, TTS, and ASR models — fine-tuning, evaluating, and improving them for production use cases
- Identify failure modes and edge cases across the pipeline (background noise, accents, interruptions, turn-taking, latency, pipeline-stage handoffs) and build systems to catch them before production
- Collaborate closely with engineering to integrate quality checks and automation into the voice agent development lifecycle within the Pipecat-based architecture
Qualifications
Required Qualifications
- 4–6 years of experience, with a specialization in voice AI systems and automated quality evaluation
- Hands-on experience with STT (Speech-to-Text), TTS (Text-to-Speech), and ASR (Automatic Speech Recognition) models
- Experience designing and building automated testing/evaluation frameworks for voice or speech systems
- Strong understanding of what drives voice AI quality — accuracy, latency, naturalness, and robustness to real-world variability
- Strong programming skills in Python; familiarity with Pipecat or similar voice pipeline/orchestration frameworks is a plus
- Understanding of STT → LLM → TTS pipeline architectures and the trade-offs involved at each stage
- Research mindset — comfortable exploring new models, techniques, and tools and translating them into practical improvements
- Excellent communication skills — this is a customer-facing role, and you'll regularly engage directly with customers to understand needs and validate quality expectations
