Tech Lead to lead the LLM & Generative AI team at EverAI, a fast-growing AI companionship platform with 50 million users. The role involves hands-on coding, owning the model lifecycle, and architecting high-precision moderation systems for a large-scale, uncensored conversational AI platform.
What You'll Do
- 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 strategy for SFT (Supervised Fine-Tuning) and RLHF/DPO (Preference Optimization)
- 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
- 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
What We're Looking For
- 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
- Understand the technical rigor required to moderate NSFW content effectively without breaking the user experience
- Intuition for Alignment: understand 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
