Responsibilities
Ship Code & Lead from the Front
Act as a Player/Coach: Architect the system and mentor the team, but spend significant time hands-on in the codebase (Python/PyTorch)
Own the core chat loop: Optimize context windows, memory/RAG retrieval, and inference latency to ensure a seamless, real-time experience
Own the Model Lifecycle
Drive our strategy for SFT (Supervised Fine-Tuning) and RLHF/DPO (Preference Optimization). You decide when to prompt, when to fine-tune, and when to architect a new RAG pipeline
Manage the "Data Engine": oversee the sourcing, labeling, and cleaning of diverse datasets to improve model steerability and multicultural performance
Architect High-Precision Moderation
Build the immune system of the platform. You will design and train custom classifiers to detect and filter non-consensual or illegal content within an explicit environment
Move beyond binary "safe/unsafe" flags to create nuanced, context-aware moderation systems

You can distinguish between a 'perfect' academic solution and a 'shippable' production solution
You don't rent code
You obsess over metrics, regressions, and the user experience long after the code has been merged
