Key Responsibilities
AI Model Training — Code Development & Optimization
- Design, develop, and maintain efficient, high-quality, production-standard code specifically oriented toward training and optimizing AI models — applying software engineering best practices to AI model development workflows that demand both technical rigor and rapid iteration
- Write clean, readable, reusable, and maintainable code across Python and JavaScript/TypeScript stacks — ensuring that all AI training and evaluation code meets the professional engineering standard expected when collaborating with leading US-based AI research and product teams
- Conduct thorough peer reviews of code and technical documentation — maintaining collaborative engineering quality standards across a cross-functional, globally distributed team of developers, researchers, and annotators
- Utilize Docker for containerization and deployment of AI model training environments — ensuring reproducible, portable, and reliably deployable development and evaluation infrastructure
Model Evaluation, Benchmarking & Performance Analysis
- Conduct rigorous evaluations (evals) to benchmark AI model performance across diverse task types and domains — designing systematic evaluation frameworks that measure model capability accurately and surface meaningful performance gaps
- Analyze evaluation results for continuous AI model improvement — translating benchmarking outputs into specific technical recommendations that inform training adjustments, fine-tuning priorities, and reward model refinements
- Evaluate and rank AI model responses to user queries across a wide range of domains — applying both technical judgment and domain knowledge to ensure model outputs consistently align with predefined quality, accuracy, and safety criteria
- Apply performance measurement tools and methodologies to track model improvement over successive training iterations — maintaining clear, documented records of evaluation baselines, test results, and performance trajectory
Supervised Fine-Tuning (SFT) — Dataset Creation & Management
- Lead efforts in supervised fine-tuning (SFT) — creating, curating, and maintaining high-quality, task-specific training datasets that provide the instruction-following signal required to align AI model behavior with specific commercial or research use case requirements
- Design SFT dataset creation workflows that ensure consistent quality, diversity, and appropriate coverage of the task domain — applying systematic quality assurance processes to every dataset component before use in model fine-tuning
- Maintain comprehensive documentation for SFT datasets — tracking data provenance, annotation guidelines, quality metrics, and version history in a way that ensures reproducibility and supports ongoing dataset maintenance and improvement
- Collaborate closely with AI researchers to understand the specific behavioral objectives of each fine-tuning initiative — ensuring that dataset design decisions are grounded in a shared understanding of the technical and commercial goals being pursued
RLHF — Reinforcement Learning with Human Feedback
- Collaborate with AI researchers and human annotators to execute reinforcement learning with human feedback (RLHF) workflows — contributing to the data collection, comparison labeling, and preference dataset construction processes that train reward models and improve AI behavior alignment
- Refine reward models through iterative RLHF cycles — analyzing reward model outputs, identifying systematic biases or failure modes, and recommending targeted improvements to the training data, ranking methodology, or model architecture
- Support the full RLHF pipeline from human preference data collection through reward model training and policy optimization — contributing engineering expertise that ensures the pipeline operates reliably, reproducibly, and at the quality standard required for frontier model development
