AI Research Engineer

Summary

Join Tether's AI model team and drive innovation in supervised fine-tuning methodologies for advanced models. Refine pre-trained models to deliver enhanced intelligence and optimized performance for real-world challenges. Work on a wide spectrum of systems, from streamlined models for limited hardware to complex multi-modal architectures. You will leverage deep expertise in large language model architectures and fine-tuning optimization. Adopt a hands-on, research-driven approach to developing, testing, and implementing new techniques and algorithms. Responsibilities include curating specialized data, strengthening baseline performance, and resolving fine-tuning bottlenecks. The goal is to unlock superior domain-adapted AI performance.

Requirements

• A degree in Computer Science or related field
• Ideally PhD in NLP, Machine Learning, or a related field, complemented by a solid track record in AI R&D (with good publications in A* conferences)
• Hands-on experience with large-scale fine-tuning experiments, where your contributions have led to measurable improvements in domain-specific model performance
• Deep understanding of advanced fine-tuning methodologies, including state-of-the-art modifications for transformer architectures as well as alternative approaches. Your expertise should emphasize techniques that enhance model intelligence, efficiency, and scalability within fine-tuning workflows
• Strong expertise in PyTorch and Hugging Face libraries with practical experience in developing fine-tuning pipelines, continuously adapting models to new data, and deploying these refined models in production on target platforms
• Demonstrated ability to apply empirical research to overcome fine-tuning bottlenecks. You should be comfortable designing evaluation frameworks and iterating on algorithmic improvements to continuously push the boundaries of fine-tuned AI performance

Responsibilities

• Develop and implement new state-of-the-art and novel fine-tuning methodologies for pre-trained models with clear performance targets
• Build, run, and monitor controlled fine-tuning experiments while tracking key performance indicators. Document iterative results and compare against benchmark datasets
• Identify and process high-quality datasets tailored to specific domains. Set measurable criteria to ensure that data curation positively impacts model performance in fine-tuning tasks
• Systematically debug and optimize the fine-tuning process by analyzing computational and model performance metrics
• Collaborate with cross-functional teams to deploy fine-tuned models into production pipelines. Define clear success metrics and ensure continuous monitoring for improvements and domain adaptation
