Machine Learning Engineer

Machine Learning Engineer

What you can expect

• Designing, training, evaluating, and optimizing machine learning models for speech and language processing tasks. Developing scalable ML pipelines for large-scale data processing and model deployment.
• Handling, curating, and synthesizing training and testing data while automating pipelines for efficient data processing. Implementing advanced evaluation frameworks for translation scenarios, including streaming speech-to-text and speech-to-speech translation.
• Working with advanced speech synthesis systems, customizing and integrating them into existing systems to enhance performance and user experience. Collaborating with researchers and engineers to integrate models into production environments.
• Experimenting with new techniques in deep learning, LLM fine-tuning, and model alignment to drive innovation and improve system capabilities. Analyzing model performance to identify areas for continuous improvement.
• Contributing to research initiatives through prototyping, experimentation, and publishing where applicable. Maintaining high standards of code quality, reproducibility, and technical documentation.
• Engaging in cross-functional projects with global teams to deliver innovative AI solutions to market. Supporting collaboration and knowledge sharing across research and engineering teams.
• Ensuring systems and processes align with organizational goals for scalability, efficiency, and innovation. Continuously refining methods to enhance model accuracy and deployment efficiency.

• Bring 2+ years of experience; or a Master’s/Ph.D. in Computer Science, Artificial Intelligence, Machine Learning, or related fields.
• Demonstrate depth and breadth in state-of-the-art machine learning methods. This includes neural network training, LLM training, and post-training techniques (e.g., preference optimization and reinforcement learning with human feedback). Consider experience with speech transcription, machine translation, speech translation or speech synthesis as advantageous, though not required.
• Show advanced coding skills in Python, C/C++, or Java.
• Apply hands-on experience with machine learning model development using frameworks such as PyTorch, TensorFlow, or JAX.
• Work with large-scale text and/or audio data processing and distributed systems.
• Use proven mathematical knowledge and understanding of machine learning and statistics.
• Contribute effectively within a team environment.
• Bring the following, which would be nice to have: experience building deep learning models in PyTorch. Train and evaluate multilingual or multimodal LLMs, and optimize distributed training on GPUs. Also, communicate clearly in writing and verbally, and have a record of publishing in top-tier conferences such as COLM, NeurIPS, ACL, EMNLP, and ICLR.
