Machine Learning Engineer (TTS)

We are fully Remote and can hire across Europe!

At Praktika.ai we are on a mission to deliver efficient and engaging learning experiences for billions of students worldwide by bridging the gap between learning apps and human tutors.

We have done this by creating a fully automated language tutorship experience powered by generative AI Avatars.

After raising $30 million in Series A funding, we are growing and looking for a TTS/SST Machine Learning Engineer to join us! We are a global small team of 40 innovators who are pushing the boundaries of what’s possible in language learning and tutoring.

This is a unique opportunity to shape the voice of next-generation AI systems — from real-time conversational pipelines to emotionally expressive speech synthesis. If you're passionate about TTS, real-time AI, and scaling machine learning systems, we’d love to talk to you.

In this fast-paced environment we like independent self-starters who can work well in a team as well as unassisted and who enjoy the working environment of an early-stage startup.

What You’ll Do with us:

• Design, integrate, and optimize Text-to-Speech (TTS) systems within real-time conversational AI pipelines.
• Fine-tune models based on user feedback, improving clarity, naturalness, and emotional expression in voice output.
• Contribute to customer-specific deployments with high adaptability and quick turnaround requirements.
• Collaborate with ML, product, and engineering teams to ensure seamless voice experiences across our platform.

What we’re Looking For from you: 

• Strong proficiency in Python, with deep knowledge of software development principles, architecture patterns, and ML model integration.
• Hands-on experience with TTS systems (e.g., Tacotron, FastSpeech, VITS) and an understanding of SST pipelines.
• Familiarity with real-time AI systems, including LLM integration and latency-sensitive applications.
• Experience tuning and maintaining ML models for performance, scalability, and quality in production.
• Bonus: Experience with Pytest or other testing frameworks for ML systems.

Why should you join Praktika:

• Be part of the story of one of the fastest-growing early-stage consumer AI companies globally
• Work with a highly ambitious team using the best technologies on the market
• Drive innovation and make a significant impact in the AI and education sectors
• Competitive salary
• Flexibility to work remotely
• Health and wellness benefits to support your overall well-being
• Opportunity for rapid career growth and personal development
• Access to an AI toolkit including ChatGPT, Copilot, and other productivity tools
• Annual educational budget of up to $1,000
