Requirements
  • You have shipped Artificial Intelligence at scale. You have 8+ years of engineering experience, with a significant portion dedicated to shipping ML/LLM features to millions of active users.
  • You are deeply technical. You are proficient in Python/PyTorch and comfortable with the modern large language model stack (vLLM, HuggingFace, fine-tuning pipelines, eval frameworks).
  • You understand the "Uncensored" challenge. You are comfortable working with NSFW content and understand the technical rigor required to moderate it effectively without breaking the user experience.
  • Intuition for Alignment: You understand the physics of large language models—how prompt conditioning, temperature, and sampling affect the "soul" of a chatbot.
  • Doer Mindset: You value velocity. You can distinguish between a "perfect" academic solution and a "shippable" production solution.
  • Owner: You don't rent code. You obsess over metrics, regressions, and the user experience long after the code has been merged.
Responsibilities
  • 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.
  • 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.
