Description provided by SONALAB
About us
SONALAB builds Voice AI for professional media production: human-quality dubbing and voice generation that integrates directly into standard editing suites such as Pro Tools, Nuendo and DaVinci Resolve. Together with Fraunhofer IIS we deliberately train our models on licensed, fully traceable data. To support our CTO, Sören Hübner, we are looking for a motivated working student to join our team.
Your tasks
- Support quality control: evaluating generated audio and dubbing outputs for naturalness, speaker identity, emotion and pronunciation, including structured documentation of the results.
- Research work: reviewing current methods, models and academic publications (e.g. TTS, voice conversion, speech-to-speech) and monitoring competitors and the market.
- Contributing to smaller development tasks around tooling, data pipelines and evaluation scripts.
- Working directly with the CTO and gaining hands-on involvement in an early-stage, technically demanding product.
Your profile
- Enrolled in a Computer Science, IT-Systems Engineering or related degree program.
- Enthusiasm for AI/ML, ideally with a connection to audio, speech or signal processing.
- Solid Python or C++ skills; first experience with ML frameworks such as PyTorch, Keras or Tensorflow is a plus.
- A careful, independent way of working and a good ear for audio quality.
- Strong command of English; German is a plus.
What we offer
- Real responsibility and insight into the full ML and application lifecycle, from prototype to production deployment.
- Collaboration with an experienced founding team and with Fraunhofer IIS.
- Flexible working hours, hybrid and remote work, and a mission with real societal relevance: ethical, EU-sovereign Voice AI.
The essentials
Position: Working student / student assistant
Hours: 10–20 hrs/week, flexible alongside your studies
Start: immediately
Location: hybrid / remote

Working student essentials
What this Tech working student role in Berlin means for you — the weekly-hours rules, social-contribution perks, and what international students should check before applying.
Weekly hours
Working students may work up to 20 hours a week during the semester and full-time during the breaks. Staying within this keeps your student status and the Werkstudent benefits.
Working student rulesSocial contributions
Under the Werkstudentenprivileg you're exempt from health, care and unemployment insurance contributions — only pension insurance applies. That leaves more net pay than a regular job.
Check your insuranceInternational students
Non-EU students can work 140 full or 280 half days per year (raised from 120/240 in March 2024). A working student contract usually fits within this — confirm the exact limits printed on your residence permit.
