EverAI is seeking a Tech Lead to lead their LLM & Generative AI team in a fully remote role based in Montenegro. This individual will own the architecture, training, and deployment of models powering the world’s largest AI companionship platform, used by 50 million users. The role demands hands-on technical leadership, deep expertise in large-scale LLM systems, and experience shipping AI features at production scale.
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)
- 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
Requirements
- 8+ years of engineering experience, with a significant portion dedicated to shipping ML/LLM features to millions of active users
- Deeply technical with proficiency 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 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
Tech Stack
Python, PyTorch, vLLM, HuggingFace, fine-tuning pipelines, eval frameworks
