About Us


We’re a very young startup founded by two co-founders, building advanced speech AI solutions. Our goal is to train and deploy highly accurate, production-ready models optimized for real-world phone and conversation data in Turkish.



The Role


We’re looking for a Deep Learning Engineer with hands-on expertise in speech models. This is not a full-time role, but rather a project-based collaboration that can evolve into something bigger as we grow.


You’ll be responsible for:


  • Fine-tuning and training STT models (e.g., Whisper, NeMo).
  • Designing, implementing, and optimizing deep learning architectures for speech tasks.
  • Conducting large-scale data preprocessing, augmentation, and evaluation.
  • Training and deploying models on GPU infrastructure.
  • Iterating to improve real-world accuracy and latency.
  • Collaborating with our small team to bring models into production environments.



What We’re Looking For


  • Experience training speech models (STT is a priority, TTS is a plus).
  • Solid understanding of the end-to-end ML/DL pipeline: data → training → deployment → scaling.
  • Proficiency in PyTorch (preferred).
  • Strong programming skills in Python.
  • Familiarity with distributed training on GPUs.
  • Up-to-date with the latest research in deep learning and speech technologies.
  • English fluency required (and ideally Turkish speaker).



Why Join Us?


  • Freelance / contract flexibility.
  • Opportunity to contribute to cutting-edge speech AI at an early stage.
  • Potential for long-term collaboration as we scale.
  • Work directly with the co-founders on exciting, high-impact projects.
