Requirements
- 8+ years of engineering experience, with a significant portion dedicated to shipping ML/LLM features to millions of active users
- Proficient in Python/PyTorch
- Comfortable with the modern LLM stack (vLLM, HuggingFace, fine-tuning pipelines, eval frameworks)
- Comfortable working with NSFW content and understand the technical rigor required to moderate it effectively
- Intuition for Alignment: understanding how prompt conditioning, temperature, and sampling affect the "soul" of a chatbot
- Doer Mindset: value velocity and can distinguish between a "perfect" academic solution and a "shippable" production solution
- Owner: obsess over metrics, regressions, and the user experience long after the code has been merged
Responsibilities
- Act as a Player/Coach, architecting the system and mentoring the team, while spending 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 the strategy for SFT (Supervised Fine-Tuning) and RLHF/DPO (Preference Optimization)
- Manage the "Data Engine": oversee the sourcing, labeling, and cleaning of diverse datasets to improve model steerability and multicultural performance
- Build the immune system of the platform, designing and training 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
