What You’ll Do:

We are looking for a Machine Learning Engineer with specialized expertise in Large Language Model (LLM) fine-tuning and speech recognition technologies. As part of our AI-focused startup studio, you will play a pivotal role in training and optimizing large-scale AI models, pushing the boundaries of what’s possible with language-based models and real-time applications.

This role demands not only deep technical skills but also a strong understanding of LLM architectures, fine-tuning techniques, and the application of transfer learning to domain-specific tasks. You will be expected to work with cutting-edge methodologies and engage with tools like LoRA (Low-Rank Adaptation) and RLHF (Reinforcement Learning from Human Feedback) for model optimization. You should also be ready to bring creative, efficient solutions to the challenges of real-time model deployment.

Key Responsibilities:

Develop Speech Recognition Models: Design, build, and fine-tune speech recognition models using the latest advancements in deep learning and AI.
Fine-tune LLMs: Leverage state-of-the-art techniques like LoRA to fine-tune large language models to domain-specific tasks and optimize model performance.
LLM Scaling & Optimization: Tackle challenges in model scaling, memory efficiency, and performance optimization for real-time applications.
Domain Adaptation: Use transfer learning techniques to adapt general LLMs to specific domains or tasks, such as fine-tuning for specific dialogue systems, NLP tasks, or industry-specific applications.
Collaborative Problem-Solving: Work with cross-functional teams to integrate AI models into production environments and ensure real-world effectiveness.

What We Expect:

Deep knowledge of transformer-based architectures (e.g., GPT, BERT, T5, LLaMA), with a focus on model pre-training, fine-tuning, and optimization.
Hands-on experience with LLM fine-tuning, LoRA, parameter-efficient tuning, and techniques for improving generalization and task adaptation.
Experience in speech recognition systems, including ASR models and audio processing techniques.
Strong familiarity with real-time optimization techniques and the challenges of deploying LLMs in low-latency environments.
Comfort with experiment tracking and hyperparameter tuning for training large models at scale.

Additional Experience We’d Like:

Working with LLMs beyond traditional fine-tuning, such as RLHF or using techniques to align models with human preferences.
Practical experience with distributed training and fine-tuning frameworks like Hugging Face Transformers, DeepSpeed, Accelerate, or Megatron-LM.
Knowledge of data-efficient training methods, including few-shot learning, zero-shot learning, and active learning.
