• Conduct experiments, track results, and optimize model performance using tools such as Hydra and Weights & Biases.
• Work with audio/voice processing technologies, including text-to-speech (TTS) and speech-to-text (STT).
• Implement efficient similarity and nearest-neighbor search using Faiss and other retrieval frameworks.
• Collaborate with cross-functional teams to integrate ML models into production systems and deliver scalable, real-world solutions.
• Manage and manipulate large datasets, ensuring high data quality and reproducibility.
• Contribute to shared codebases with strong use of Git/GitHub, following best practices for version control and code reviews.
• Prepare clear documentation, procedural guidelines, and technical reports for both internal and external stakeholders.
• Provide mentorship and technical guidance to junior engineers where needed.
• Support the deployment and monitoring of ML systems on remote servers, ensuring stability and continuous optimization.
