What you will accomplish:
Model Development & Optimization
- Lead the full lifecycle of AI/ML models, focusing on performance improvements through fine-tuning, architectural experimentation, and continuous refinement.
- Develop and maintain datasets for training and evaluation using real-world and synthetic generation methods.
- Apply grounding strategies and fine-tune LLMs and vision models to enhance factual accuracy and reduce hallucinations.
- Explore new modeling approaches and training methodologies that advance system capabilities.
LLM Evaluation & Continuous Learning
- Design and maintain evaluation pipelines to systematically assess model quality across relevance, correctness, robustness, and user impact.
- Conduct detailed error analysis and performance tracking to identify areas for continuous improvement.
- Automate evaluation gates in CI/CD pipelines and support learning loops through strategic annotation and data sampling.
Tooling & Product Impact
- Collaborate with Product and Data teams to align modeling goals with product outcomes and application needs.
- Develop internal tools and utilities to support model experimentation, benchmarking, and validation processes.
- Instrument applications for observability and help monitor model behavior in production environments.
Who you are:
- A researcher-practitioner with a strong foundation in training, fine-tuning, and evaluating modern AI/ML models.
- Focused on improving model performance through thoughtful experimentation, evaluation rigor, and high-quality data.
- Collaborative, communicative, and motivated to solve real-world problems with cutting-edge techniques.
- Capable of supporting engineering efforts where needed—especially those that enable better model evaluation and iteration.
What you bring:
- PhD in Computer Science, Machine Learning, NLP, or a related field—recent graduates are strongly encouraged to apply.
- Strong understanding of LLMs, fine-tuning methods (LoRA, PEFT, RLHF), and evaluation frameworks (LLM-as-a-judge, inter-annotator agreement, etc.).
- Experience with Python and ML libraries such as PyTorch, HuggingFace Transformers, and vLLM.
- Hands-on experience with dataset curation, training loop design, and architecture search.
- Familiarity with tools such as Weights & Biases, MLflow, or LangChain for tracking and analysis.
- Engineering experience (e.g., API exposure, model deployment) is a plus but not a strict requirement.
